+ + + + + + This guide explains both basic usage of the USRP as well as how to expand it. + + + + + + + Introduction + + The Universal Software Radio Peripheral, or USRP (pronounced "usurp") + is designed to allow general purpose computers to function as high + bandwidth software radios. In essence, it serves as a digital + baseband and IF section of a radio communication system. In addition, + it has a well-defined electrical and mechanical interface to RF + front-ends (daughterboards) which can translate between that IF or + baseband and the RF bands of interest + + + The basic design philosophy behind the USRP has been to do all of the + waveform-specific processing, like modulation and demodulation, on the + host CPU. All of the high-speed general purpose operations like + digital up- and downconversion, decimation and interpolation are done + on the FPGA. + + + It is anticipated that the majority of USRP users will never need to + use anything other than the standard FPGA configuration. However, for + those users that wish to, the FPGA design may be changed or replaced. + All of the interfaces are well defined and documented. + +
+ USRP with Daughterboards + + + + This USRP has 2 BasicTX and 2 BasicRX boards mounted on it. + Notice that the boards on the left are rotated 180 degrees. + + +
+ + + System Requirements + + The USRP requires a PC or Mac with a USB2 interface. + + + + + Capabilities + + The USRP has 4 high-speed analog to digital converters (ADCs), each at + 12 bits per sample, 64 million samples per second. There are also + 4 high-speed digital to analog converters (DACs), each at 14 bits per + sample, 128 million samples per second. These 4 input and 4 output + channels are connected to an Altera Cyclone EP1C12 FPGA. The FPGA, in + turn, connects to a USB2 interface chip, the Cypress FX2, and on to the + computer. The USRP connects to the computer via a high speed USB2 + interface only, and will not work with USB1.1. + +
Universal Software Radio Peripheral + + + + + +
+ + + + Getting Started + + Getting all the Software + + The first step in using your USRP system is to get all of GNU Radio installed. This can + sometimes be a daunting process, as there are several other libraries which will need to be + installed first. + + + Library Dependencies + + + SWIG + + We use SWIG (Simple Wrapper Interface Generator) to tie together the C++ and Python code + in the GNU Radio system. We require that you have version 1.3.24 or newer. You'll + probably have to compile it from source, which you can find here: SWIG + + + + FFTW + + FFTW is the library which GNU Radio uses for FFTs. GNU Radio requires version 3.0.1 or + newer, and it must be compiled for single precision. You can get it from the + FFTW Homepage + + + + Boost Library + + Boost provides several low-level structures used in our C++ code. If it is not included in + your OS distribution, you can get it here: Boost + + + + CPP Unit + + CPPUnit provides our unit-testing framework. This creates automated tests to insure that + code does not break when changes are made. Get it at the + CPP Unit Homepage + + + + + + Getting GNU Radio and the USRP code + + There are several packages of software which make up GNU Radio and the USRP support software. + Links to the latest versions of each can be found on the GNU Radio Wiki at + Download Links. Gr-build + can greatly simplify the installation process, and its use it highly recommended. + + + + Following CVS Development + + Development for the USRP proceeds very quickly at times, so some users may want to keep up with + the latest by following the CVS trees. There are three separate software repositories + which contain various parts of the USRP system. + + + + USRP-HW, containing the hardware and FPGA designs. + + + All of the schematics in this repository were created in + gEDA. The board + layouts were created in PCB. + Verilog designs are compiled in Quartus II Web Edition from + Altera. + + + + + USRP-SW, + USRP-SW, containing firmware and host drivers for the USRP + + + Host side drivers and firmware which runs in the USB2 interface chip on the board. + + + + + GNU Radio/gr-usrp + which contains the GNU Radio interface to the USRP + + + + + + + + Using your USRP + + Mechanical Connection + + The USRP ships with a complete set of standoffs, nuts and bolts. There are 20 standoffs, + M3x10mm M-F, of which 4 are intended to be used as "feet" for the USRP. Place them in the 4 + corner holes on the main board, inserting the male part from below. The remaining 16 + are used to hold the daughterboards in place. Four of them should be connected to the male + portion of the 4 standoffs already inserted from below. The remaining 12 should be + connected to the board with the 12 M3x6mm screws from below. At this point there should be + 16 standoffs on the board with the male ends up to serve as a guide for the daughterboards. + The 16 M3 nuts are used to fasten the daughterboards down to the main board. + + + The USRP accomodates 2 TX and 2 RX daughterboards. The placement of the standoffs is designed + to prevent the accidental incorrect connection of daughterboards. The 2 sides of the USRP have + their daughterboard slots rotated 180 degrees. The USRP should not be operated without + standoffs, and daughterboards should never be connected or removed while power is applied. + + + + Electrical Connections + + The USRP is powered by a 6V 4A power converter included in the kit. The converter is + capable of 90-260 Vac, 50/60 Hz operation, and so should work in any country. + If there is a need to use another power supply, the connector is a standard 2.1mm/5.5mm + DC power connector. The USRP itself only needs 5V at 2A, but a 6V supply was chosen to + accomodate future daughterboards. Extra power supplies are available from Ettus Research. + + + The included USB cable should be connected to a USB2-capable socket on a computer. The USRP + does not support USB 1.1 operation at this time. + + + + Troubleshooting + + When first powered up, an LED on the USRP should be flashing at about 3-4x per second. + This indicates that the processor is running, and has put the device in a low power mode. + Once firmware has been downloaded to the USRP, the LED will blink at a slower rate. + If there is no blinking LED, check all power connections, and check for continuity + in the power fuse (F501, near the power connector). If the fuse needs replacement, it + is size 0603, 3 amps. + + + + + + FPGA + + Standard FPGA Configuration + + In the standard fpga configuration, usrp_std, all samples sent over + the USB interface are in 16-bit signed integers in IQ format. When + there are multiple channels (up to 4), the channels are interleaved. + For example, with 4 channels, the sequence would be I0 Q0 I1 Q1 I2 Q2 + I3 Q3 I0 Q0, etc. + + + The USRP can operate in full duplex mode. When in this mode, the + transmit and receive sides are completely independent of one another. + The only consideration is that the combined data rate over the bus + must be 32 Megabytes per second or less. The multiple RX channels + (1,2, or 4) must all be the same data rate (i.e. same decimation + ratio). The same applies to the 1,2, or TX channels, which each must + be at the same data rate (which may be different from the RX rate). + + + On the RX side, each of the 4 ADCs can be routed to either of I or the + Q input of any of the 4 downconverters. This allows for having + multiple channels selected out of the same ADC sample stream. + + + The digital upconverters (DUCs) on the transmit side are actually + contained in the AD9862 CODEC chips, not in the FPGA. The only + transmit signal processing blocks in the FPGA are the interpolators. + The interpolator outputs can be routed to any of the 4 CODEC inputs. + +
Digital Down Converter Block Diagram + + + + + +
+ + + + + Daughterboard Interface + + Power + + Daughterboards are provided with clean regulated 3.3V for the analog + and digital sections. Additionally there is a 6V connection straight from + the wall supply which is intended to supply a 5V LDO regulator. All daughterboards + may draw a combined total of 1.5 A. + + + + Logical Interface + + There are slots for 2 TX daughterboards, labeled TXA and TXB, and 2 + corresponding RX daughterboards, RXA and RXB. Each daughterboard slot has + access to 2 of the 4 high-speed data converter analog signals (DAC outputs + for TX, ADC inputs for RX). This allows each daughterboard which uses real + (not IQ) sampling to have 2 independent RF sections, and 2 antennas + (4 total for the system). If IQ sampling is used, each board can support + a single RF section, for a total of 2 for the whole system. + + + No antialias or reconstruction filtering is provided on the USRP motherboard. + This allows for maximum flexibility in frequency planning for the + daughterboards. The analog input bandwidth of the ADCs is over 200 MHz, so + IF frequencies up to that high may be chosen. If several decibels of loss + is tolerable, and IF frequency as high as 500 MHz can be used. + + + Every daughterboard has an I2C EEPROM (24LC024 or 24LC025) onboard + which identifies the board to the system. This allows the host + software to automatically set up the system properly based on the + installed daughterboard. The EEPROM may also store calibration values + like DC offsets or IQ imbalances. If this EEPROM is not programmed, a + warning message is printed every time USRP software is run. + + + + Analog Interface + + Each RX daughterboard has 2 differential analog inputs + (VINP_A/VINN_A and VINP_B/VINN_B) which are sampled at a rate of 64 MS/s. + The input impedance is approximately 1Kohm. + The motherboard has a software-controllable programmable gain amplifier + on these inputs, with 0 to 20 dB of gain. With gain set to zero, full + scale inputs are 2 Volts peak-to-peak differential. When set to 20 dB, + only .2 V pk-pk differential is needed to reach full scale. + + + If signals are AC-coupled, there is no need to provide DC bias as long as the + internal buffer is turned on. It will provide an approximately 2V bias. + If signals are DC-couple, a DC bias of Vdd/2 (1.65V) should be provided to + both the positive and negative inputs, and the internal buffer should be turned off. + VREF provides a clean 1 V reference. + + + Each TX daughterboard has a pair of differential analog outputs which are + updated at 128 MS/s. The signals (IOUTP_A/IOUTN_A and IOUTP_B/IOUTN_B) are + current-output, each varying between 0 and 20 mA. Since they are high-impedance, + they can be converted into differential voltages with a resistor. + + + In addition to the high-speed signals, each daughterboard has exclusive access to 2 low-speed ADC inputs + (labeled AUX_ADC_A and AUX_ADC_B) which can be read from software. + These are useful for sensing RSSI signal levels, temperatures, bias + levels, etc. Additionally, each board has shared access to 4 low-speed DAC + signals, labeled AUX_DAC_A through AUX_DAC_D. RXA and TXA share one set + of these 4 lines, and RXB and TXB share their own independent set. These + signals are useful for controlling gain of variable-gain amplifiers, for example. + AUX_ADC_REF provides a reference level for gain setting if it is necessary. + + + + + Digital Interface + + + + Connector Pinouts + + RX DBoard Connector + + + + Pin # + Name + Description + + + + + 1 + power + This is power + + + c1 + c4 + + + d1 + d4 + d5 + + + +

The middle section of taps looks like this: + * + * ..., -1468, 0, 2950, 0, -6158, 0, 20585, 32768, 20585, 0, -6158, 0, 2950, 0, -1468, ... + * | + * middle tap -------+ + * + * See coeff_rom.v for the full set. The taps are scaled relative to 32768, + * thus the middle tap equals 1.0. Not counting the middle tap, there are 8 + * non-zero taps on each side, and they are symmetric. A naive implementation + * requires a mulitply for each non-zero tap. Because of symmetry, we can + * replace 2 multiplies with 1 add and 1 multiply. Thus, to compute each output + * sample, we need to perform 8 multiplications. Since the middle tap is 1.0, + * we just add the corresponding delay line value. + * + * About timing: We implement this with a single multiplier, so it takes + * 8 cycles to compute a single output. However, since we're decimating by two + * we can accept a new input value every 4 cycles. strobe_in is asserted when + * there's a new input sample available. Depending on the overall decimation + * rate, strobe_in may be asserted less frequently than once every 4 clocks. + * On the output side, we assert strobe_out when output contains a new sample. + * + * Implementation: Every time strobe_in is asserted we store the new data into + * the delay line. We split the delay line into two components, one for the + * even samples, and one for the odd samples. ram16_odd is the delay line for + * the odd samples. This ram is written on each odd assertion of strobe_in, and + * is read on each clock when we're computing the dot product. ram16_even is + * similar, although because it holds the even samples we must be able to read + * two samples from different addresses at the same time, while writing the incoming + * even samples.

Speed improvements are made by porting +LIBUSB's non-true async bulk read and write functions into USRP's +"fusb", and upgrading them to handle -true- async transfers. +Unfortunately, the easiest way to do this is to spawn a thread or 2 to +handle the "async" part of the transfers. This implementation uses +Darwin's pthreads to do the work for mutexes, conditions, and threads. +Previous implementations (0.1 and before) used "omni_threads" as +provided by gnuradio-core, which caused issues with compiling and +execution ... I'm glad that this is no longer the case. + +As far as I have tested, there is no way to improve the throughput to +32+ MBps without moving into Darwin's "port"s ... a kernel-level data +transport method with a user/application layer for USB-specific +functions. Unfortunately, Apple's documentation for these "port"s is +minimal; I have learned more from reading the Darwin source code +< http://darwinsource.opendarwin.org/ > than by reading Apple's +documents! This would also require -not- using LIBUSB, of which the +removal from the rest of the USRP code would be potentially tedious. + +If you run into issues either compiling or testing the USRP on +OSX, please send me a note. + +(1) Go through the bootstrap, configure, compile, and install as +usual (e.g. see < http://www.nd.edu/~mdickens/GNURadio/ > for my +usual). + +(2) from .../usrp/host/apps : run the scripts +++++++++++++++++ +./test_usrp_standard_tx +./test_usrp_standard_rx +++++++++++++++++ + +For -all- systems I've tested on thus far, both of these return +exactly 41 overruns / underruns, and -most- systems start out with a +stalled pipe. This stall comes in a usb_control funciton call to +LIBUSB; one would have to change the LIBUSB code to handle this issue. + +(3) from gr-build/gnuradio-examples/python/usrp : +++++++++++++++++ +./benchmark_usb.py +++++++++++++++++ + +(4) If you get to here, the try doing the FM receiver (gui or not). +If that sounds correct, then the USB is working.
