TX Event Test App Guide

Description

This application directory containts several OAS files which allow for the testing of the tx_event protocol using the qdac component’s event_in port in multiple scenarios include both event_in port connected and unconnected. The application transmits a single tone at a frequency set via the tx component’s frequency_MHz property in each OAS. OAS files exist for each supported hardware setup for two different behaviors: 1) transmitted tone is toggled (on/off) at a rate of once per second (event_in port is connected), and 2) transmitted tone is constant over duration of application (event_in port is unconnected). The application duration is set via ocpirun … -t \(<\)duration_sec\(>\) …).

Example usage

Example 1 - Zedboard/FMCOMMS3 w/ SMA TX1A connected to spectrum analyzer w/ 2.4 GHz visible

OCPI_LIBRARY_PATH=../../hdl/assemblies/data_src_to_dac_test_tx_event/:../../hdl/:../../components/:$OCPI_LIBRARY_PATH ocpirun -t 10 tx_event_test_toggle_fmcomms3_control_plane_100_MHz.xml

Spectrum analyzer is used to observe tone at 2.4 GHz toggle on/off once a second for 10 sec.

Example 2 - Zedboard/FMCOMMS3 w/ SMA TX1A connected to spectrum analyzer w/ 2.4 GHz visible

OCPI_LIBRARY_PATH=../../hdl/assemblies/data_src_to_dac/:../../hdl/:../../components/:$OCPI_LIBRARY_PATH ocpirun -t 10 tx_event_test_const_tone_fmcomms3.xml

Spectrum analyzer is used to observe constant tone at 2.4 GHz for 10 sec.
