Chapter 4160
Playing a Downloaded Waveform
The following procedure shows you how to load and play a downloaded waveform file, using
front panel key presses and remote commands.
1. Select the downloaded waveform file in non-volatile waveform memory (NVWFM) and load
it into volatile waveform memory (WFM1). The file consists of both IQ and marker file
data, and therefore, requires two SCPI commands when loaded remotely.
Via the front panel:
a. Press
Mode > Dual ARB > Select Waveform > Waveform Segments > Load Store until Load
is highlighted.
b. Highlight the waveform file in the NVWFM catalog using the arrow keys or front panel
knob.
c. Press
Load Segment From NVWFM Memory. If the waveform is not highlighted, use the
cursor to highlight the waveform.
Via the remote interface, send the following SCPI commands:
:MEMory:COPY[NAME]"<NVWFM:file_name>","<WFM1:file_name>"
:MEMory:COPY[NAME]"<NVMKR:file_name>","<WFM1:file_name>"
2. Select the downloaded waveform file in volatile waveform memory for playback.
Via the front panel:
Press
Mode > Dual ARB > Select Waveform > Select Waveform .
Via the remote interface send the following SCPI command:
[:SOURce}:RADio:ARB:WAVeform "WFM1:<file_name>"
3. Play the waveform and use it to modulate the RF carrier.
Via the front panel:
a. Press
ARB Off On until On is highlighted.
b. Press
Mod On/Off until the MOD ON annunciator appears on the display.
c. Press
RF On/Off until the RF On annunciator appears on the display.
Via the remote interface, send the following SCPI commands:
[:SOURce]:RADio:ARB[:STATe] ON
:OUTPut:MODulation[:STATe] ON
:OUTPut[:STATe] ON
