Introduction

The Vanteon vProtean™ 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 vProtean 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 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.

The vProtean SDR evaluation kit is sold for evaluation purposes. If you choose to use your vProtean SDR evaluation kit to transmit using an antenna, it is the user’s responsibility to make sure that they are in compliance with all local laws and regulations.

Proper Care and Handling

All Vanteon products are thoroughly tested before shipment. The vProtean 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 nonfunctional. Listed below are some examples of actions which can prevent damage to the unit:

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

The vProtean SDR evaluation kit is supplied with heatsinks of the FPGA and transceiver IC. Under heavy processing and/or high output power levels additional airflow may be required to ensure the components remain in the specified operating temperature range to prevent damage.

Connect the supplied AC power supply to the DC Jack (J14) on the vCarrier.
Connect the AC power supply to an AC outlet.
Turn on the vProtean SDR evaluation kit by sliding the switch (SW1) on the vCarrier towards the DC Jack (J14).

User Console

The vProtean SDR evaluation kit is preloaded with a menu-based application that allows a user to perform transmit and receive functions through the USB interface. This section explains how to use the vProtean SDR evaluation application. The examples in this section refer to software version 3.4. Older versions may not support some of the features listed. To access the preloaded evaluation application connect the vProtean SDR evaluation kit USB port to a PC using the appropriate USB cable. Use a terminal emulator program (for example, PuTTY or HyperTerminal) on the PC to open a terminal session using the virtual COM port associated with the vProtean SDR evaluation kit.
To determine the appropriate virtual COM port, open Device Manager and find the associated USB Serial Port. In the example below COM4 should be used.

8.1 Main Menu
The vProtean SDR evaluation application 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:

Item	Name	Function
–	TX RX Sample Rate	Display of the pre-configured sample rate

(not user configurable)

–| FPGA Temperature| Display of the FPGA temperature
–| ADRV Temperature| Display of the ADRV IC temperature
–| RX1 RSSI| Display of RX1 receive signal strength indicator (RSSI) in dB relative to full scale
–| RX2 RSSI| Display of RX2 receive signal strength indicator (RSSI) in dB relative to full scale
–| TX1| State of the transmit (Primed/Enabled)
–| TX2| State of the transmit (Primed/Enabled)
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 Waveform Capture Settings| Configure the RX capture parameters
5| Recalibrate System| Force a transceiver recalibration
Item| Name| Function
---|---|---
C| Switch to CLI| Switch to the command line interface

Please contact Vanteon for more information on the command line interface.
Type menu in the CLI to return to the menu-based application.

8.1.1 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 a 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 PRIMED – Transmit disabled

can only be changed when TX is disabled

6| TX BOOST| Adds an additional 3 dB to the transmit
7| Toggle RX| Toggles receive for RX_ on/off
PRIMED – Receive disabled ENABLED – Receive enabled

The vProtean SDR evaluation kit is supplied with heatsinks on the FPGA and transceiver IC. Under heavy processing and/or high output power levels additional airflow may be required to ensure the components remain in the specified operating temperature range to prevent damage.
The FPGA and ADRV temperatures displayed on the main menu should be monitored by the user, and external cooling (for example, directed fan) should be applied as needed to prevent damage.

The TX Waveform Select Menu configures the waveform that is transmitted when the TX is toggled on. When the transmit is enabled, the selected 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
Item	Name	Function
---	---	---
6	Ramp	Transmits a waveform whose amplitude increases overtime
7	Chirp	Transmits a linear FM signal

8.1.2 TX1 and TX2 File Select Menu
The File Menu allows the user to select a user defined file from the SD card that specifies the transmit waveform. Use the UP and DOWN arrows on your keyboard to highlight the file you want to select and press Enter.
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 pair) per line with I and Q values separated by a comma. Channel 1 and Channel 2 data is alternated in the file, where the first line is TX1. Values must be within the range of -32768 to 32767, inclusive. See below for an example file format.

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.
The evaluation kit should be powered down whenever mounting or removing the microSD card.

8.1.3 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. Channel 1 and Channel 2 data is alternated in the file. See below for an example.
Due to a known bug in version 3.4 the first RX2 sample should be discarded prior to post processing

If the captured waveform filename has an “.iq” extension it will show up in the TX waveform list if the capture was successful.

Item	Name	Function
1	Filename	The name of the file to save the RX samples to. The filename can

be up to 9 characters. The filename extension can be up to 2 characters. It is recommended that the filename extension be “.iq”
2| Samples| The number of samples to capture. Must be a multiple of 512 IQ samples.
3| RX Channel [1,2,3]| Configure which RX channel the capture should be performed on.
1 – Capture RX1 2 – Capture RX2
3 – Capture RX1 & RX2
