5. Turn the modulation format on:
:RADio:GSM:STATe On
Modulating and Activating the Carrier
Use the following commands to modulate the carrier and turn on the RF output. For a complete
listing of SPCI commands, refer to the SCPI Command Reference.
:FREQuency:FIXed 1.8GHZ
:POWer:LEVel -10.0DBM
:OUTPut:MODulation:STATe ON
:OUTPut:STATe ON
Storing a PRAM File to Non–Volatile Memory and Restoring to Volatile Memory
After you download the file to volatile memory (waveform memory), you can then save it to
non–volatile memory. Remember that a PRAM file downloads to waveform memory. Conversely, when
you store a PRAM file to non–volatile memory, it uses the same directory as waveform files. When
storing or restoring a file, you must include the file path as part of the file_name variable.
Command Syntax
The first file_name variable is the current location of the file and its name; the second file_name
variable is the destination to store the file and its name.
There are three ways to format the file_name variable to include the file path:
Volatile Memory to Non–Volatile Memory
:MEMory:COPY "WFM1:file_name","NVWFM:file_name"
:MEMory:COPY "file_name@WFM1","file_name@NVWFM"
:MEMory:COPY "/user/bbg1/waveform/file_name","/user/waveform/file_name"
Non–Volatile Memory to Volatile Memory
:MEMory:COPY "NVWFM:file_name","WFM1:file_name"
:MEMory:COPY "file_name@NVWFM","file_name@WFM1"
:MEMory:COPY "/user/waveform/file_name","/user/bbg1/waveform/file_name"
