Zynq and FMCOMMS2/3/4 Transmitter Configuration

Connect hardware logic to FMCOMMS Zynq radio transmitter hardware

  • Library:
  • SoC Blockset Support Package for Xilinx Devices / SDR / AD9361

Description

The Zynq and FMCOMMS2/3/4 Transmitter Configuration block connects your hardware logic to the FMCOMMS2/3/4 radio transmitter hardware. In simulation, this block provides optional ports for center frequency and gain, which the SoC Builder tool maps to hardware pins. The block does not connect to the radio hardware from simulation.

Ports

Input

expand all

External RF center frequency, specified as a nonnegative finite scalar. The valid center frequency range is from 70 MHz to 6 GHz.

Dependencies

To enable this port, set the Source of center frequency parameter to Input port.

Data Types: double

External gain, specified as a numeric scalar. The valid gain range is –10 dB to 77 dB. The resolution is 0.25 dB.

Dependencies

To enable this port, set the Source of gain parameter to Input port.

Data Types: double

Parameters

expand all

Source of center frequency, specified as one of these options:

  • Dialog — Set the center frequency by using the Center frequency (Hz) parameter.

  • Input port — Set the center frequency by using the center frequency input port.

RF center frequency, in Hz, specified as a nonnegative scalar. The valid range for center frequency is 70 MHz to 6 GHz.

Dependencies

To enable this parameter, set the Source of center frequency to Dialog.

Data Types: double

Source of gain, specified as one of these options:

  • Dialog — Specify the gain by using the Gain (dB) parameter.

  • Input port — Specify the gain by using the gain input port.

Gain, in dB, specified as a numeric scalar. The valid gain range is –10 dB to 77 dB. The resolution is 0.25 dB.

Dependencies

To enable this parameter, set Source of gain to Dialog.

Data Types: double

Baseband sampling rate, in Hz, specified as a positive scalar. The valid range of this parameter is 520.834 kHz to 61.44 MHz.

Data Types: double

Advanced

Source of data, specified as one of these options:

  • Host — Transmit the input of the AD9361 Tx block.

  • DDS — Enable the direct digital synthesizer (DDS) on the radio hardware to generate transmission data. The DDS generates two additive tones for two channels. To set the frequency and scale of the tones, use the DDS frequency (Hz), DDS phase (degrees*1000), and DDS scale parameters.

DDS tone frequencies, in Hz, specified as a 2-by-2 matrix. Each channel has two additive tones. Configure channel one in the first row and channel two in the second row. For each tone, the valid range is from 0 to Baseband sample rate (Hz)/2.

Dependencies

To enable this parameter, set Data source select to DDS.

Data Types: double

DDS tone phases, in degrees times 1000, specified as a 2-by-2 matrix. Each channel has two additive tones. Configure channel one in the first row and channel two in the second row. The valid range is from 0 to 359,999. Values are relative to the maximum tone phase shift of 360 degrees, where 359,999 is 359.999 degrees.

Dependencies

To enable this parameter, set Data source select to DDS.

Data Types: double

DDS tone scale factors, in milllionths of full scale, specified as a 2-by-2 matrix. Each channel has two additive tones. Configure channel one in the first row and channel two in the second row. The valid range is –1e6 to 1e6. The values are relative to DAC output amplitude, where 1e6 is the maximum DAC output amplitude.

Dependencies

To enable this parameter, set Data source select to DDS.
