Introduction

The Vanteon vProteanTM is a 2×2 software-defined radio (SDR) that targets communications, signal intelligence, and other multi-band processing applications. It is based on the Analog Devices ADRV9004 highly integrated wideband RF transceiver and the Xilinx Zynq-7020 all programmable System-on- Chip (SoC). The protean SDR has a custom RF front end that is highly flexible, allowing its frequency range to be configured from 30 to 6000 MHz.
Each vProtean SDR is pre-loaded with the vProtean SDR Evaluation Kit (VPROKIT-21) firmware. The VPROKIT-21 firmware includes Vanteon proprietary, programmable logic cores and executable code to perform transmit and receive functions via a menu-based UI over USB enabled com port from a host computer (host not included). An encrypted Vivado Project of the VPROKIT-21’s FPGA firmware, along with the source code of the User Interface (UI) firmware is available under a free license agreement. The vProtean schematic and layout design files, and Vanteon-proprietary DSP cores are available with a paid license. Contact Vanteon Sales for more information.

Proper Care and Handling

All Vanteon products are thoroughly tested before shipment. The protean SDR is guaranteed to be functional at the time it is received by the customer. Improper use or handling of the vProtean SDR can easily cause the device to become non-functional. Listed below are some examples of actions that can prevent damage to the unit:

1. Never allow metal objects to touch the circuit board while powered.
2. Always properly terminate the transmit port with an antenna or 50 loads.
3. Always handle the board with proper anti-static methods.
4. Never allow the board to directly or indirectly come into contact with any voltage spikes.
5. Never allow any water, or condensing moisture, to come into contact with the boards.
6. Never apply more than 0 dBm of power to any RF input.
7. Always use at least 30dB attenuation if operating in a loopback configuration.

The protean SDR is sold for evaluation purposes and test equipment. If you choose to use your vProtean and Carrier to transmit using an antenna, it is your responsibility to make sure that you are in compliance with all laws for the country, frequency, and power levels in which the device is used. Additionally, some countries regulate reception in certain frequency bands. Again, it is the responsibility of the user to maintain compliance with all local laws and regulations.

Software versions and Support HW

User Console

If the vProtean SDR was purchased as part of an evaluation kit, it is preloaded with a menu-based application that allows a user to perform transmit and receive functions. This section explains how to use the vProtean SDR evaluation application. Note that the evaluation kit application does not provide access to the full capabilities of the vProtean SDR platform.
6.1 UART
The simplest method to access the preloaded test application on the vProtean SDR is to mount it to a the Vanteon Carrier board. The Carrier board provides a serial console interface via the Type-C USB connector. Connect the vProtean Carrier Board to a PC using the appropriate USB cable. Use a terminal emulator program on the PC to open a terminal session using the virtual COM port associated with the vProtean Carrier Board. The serial port parameters are: 115200 baud, 8 bits, no parity, 1 stop bit, no handshaking.
6.2 Main Menu
The vProtean software defined radio has a hierarchical menu structure that allows you to configure the radio and to transmit and receive test waveforms. The main menu consists of the following status and commands:

–| RX2 RSS| Display of RX2 RSSI
1| TX1 RX1 Settings| Configure TX1 and RX1
2| TX2 RX2 Settings| Configure TX2 and RX2
3| Capture RX| Initiate RX capture according to RX capture settings
4| RX Capture Waveform Settings| Configure the RX capture parameters
5| Recalibrate System| Force a transceiver recalibration

6.2.1 TX1/RX1 and TX2/RX2 Settings Menu
There are two submenus for configuring the TX1/RX1 and TX2/RX2 pairs. This section covers both submenus and refers to TX1 and TX2 as a generic TX, and RX1 and RX2 as generic RX.

Item| Name|

Function

---|---|---
1| TX/RX Frequency| Set the TX/RX frequency (30 MHz to 6000 MHz)
2| Toggle TX| Toggles transmit for TX on/off
3| TX Waveform Select| Go to TX waveform and select menu
4| Digital Attenuation (dB)| Attenuation that is applied digitally to the transmit waveform (0 to 100 dB)
5| TX Front End Atten (dB)| Sets the attenuation in the ADRV9004 (0 to 41.5 dB), the value can only be changed when TX is enabled
6| TX BOOST| Adds an additional 3 dB to the transmit
7| Toggle RX| Toggles receive for RX on/off

Note: The vProtean SDR may require external cooling, should both transmit channels be used continuously. The FPGA and ADRV temperatures displayed on the main menu should be monitored by the user, and external cooling (i.e. directed fan) should be applied as needed.
6.2.2 TX1 and TX2 Waveform Select Menu
The TX Waveform Select Menu configures the wave form that is transmitted when the TX is toggled on. When the transmit is enabled, the selectthe ed waveform is transmitted repeatedly.

Item| Name|

Function

---|---|---
–| Current Waveform| Display the current selected waveform
1| Zeros| Fills transmit buffer with zero waveform
2| CW| Single tone at carrier frequency
3| USB Tone, Offset=FS/32| Upper side band waveform, FS=sample rate
4| Dual Tone, Offset=FS/32+FS/8| Dual tone waveform, FS=sample rate
5| File| Go to file select menu to load waveform file from SD card

6.2.3 TX1 and TX2 File Select Menu
The File Menu allows the user to select a user-defined file that specifies the transmit waveform.
The file must exist on the SD card to be listed in this menu. The format of the filename must have a “.iq” extension to show up in the file list. The format of a transmit waveform is a . CSV file with one sample (IQ p air) per line with I and Q values separated by a comma.
For Version 1.x Software
The TX waveform file must contain between a minimum of 256 samples and a maximum of 2,097,150 samples, inclusive.
For Version 2. x and 3. x Software
The TX waveform file must contain between a minimum of 512 samples and a maximum of 4,194,304 samples, inclusive. The number of samples should be a multiple of 512. If the number of samples is not a multiple of 512, the TX waveform will be zero-padded to the next multiple of 512.
Note: The vProtean SDR and Carrier board should be powered down whenever mounting or removing the SD card.
6.2.4 RX Waveform Capture Settings Menu
The RX Waveform Capture Settings Menu allows the user to set the number of samples captured and the file to which the samples are saved. It also allows the user to configure which RX channel will be captured.
The format of a captured waveform is a . CSV file with one sample (IQ pair) per line with I and Q values separated by a comma.
If the captured waveform filename has a “.iq” extension it will show up in the TX waveform list if the capture was successful.
For Version 1.x Software
The number of RX samples to capture must be between a minimum of 256 samples and a maximum of 2,097,150 samples, inclusive.
For Version 2. x Software
The number of RX samples to capture must be a multiple of 512. If it is not a multiple of 512 the capture will fail.

Item
