Creating and Downloading Waveform Files
Loading, Playing, and Verifying a Downloaded Waveform
Loading, Playing, and Verifying a Downloaded Waveform
The following procedures show how to perform the steps using SCPI
commands. For front panel key commands, refer to the User’s Guide or to the
Key help in the signal generator.
Loading a File from Non–Volatile Memory
Select the downloaded I/Q file in non–volatile (NVWFM) and load it into
volatile (WFM1). The file comprises three items: I/Q data, marker file, and file
header information.
Send one of the following SCPI command to copy the I/Q file, marker file and
file header information:
:MEMory:COPY:NAME "<NVWFM:file_name>","<WFM1:file_name>"
:MEMory:COPY:NAME "<NVMKR:file_name>","<MKR1:file_name>"
:MEMory:COPY:NAME "<NVHDR:file_name>”,"<HDR:file_name>"
Playing the Waveform
Play the waveform and use it to modulate the RF carrier.
1. List the waveform files from the volatile memory waveform list:
Send the following SCPI command:
:MMEMory:CATalog? "WFM1:"
2. Select the waveform from the volatile memory waveform list:
Send the following SCPI command:
:SOURce:RADio:ARB:WAVeform "WFM1:<file_name>"
3. Play the waveform:
Send the following SCPI commands:
:SOURce:RADio:ARB:STATe ON
:OUTPut:MODulation:STATe ON
:OUTPut:STATe ON
When you copy a waveform file, marker file, or header file information from
volatile or non–volatile memory, the waveform and associated marker and
header files are all copied. Conversely, when you delete an I/Q file, the
associated marker and header files are deleted. It is not necessary to send
separate commands to copy or delete the marker and header files.
If you would like to build and play a waveform
sequence, refer to “Building
and Playing Waveform Sequences” on page 248.
