2. Send a "Device Clear" command from the control instrument to the R&S FPL1000
to clear all currently active remote channels. Depending on the used interface and
protocol, send the following commands:
● Visa :
viClear()
The remote channel currently processing the incompleted command is then ready
to receive further commands again.
3. On the remote channel performing the measurement, send the SCPI command
ABORt
to abort the current measurement and reset the trigger system.
4. If the R&S FPL1000 still does not react to the remote commands, switch it off and
back on.
Ignored commands
When a remote command attempts to define incompatible settings, the command is
ignored and the instrument status remains unchanged, i.e. other settings are not auto-
matically adapted. Therefore, control programs should always define an initial instru-
ment status (e.g. using the *RST command) and then implement the required settings.
Detecting false commands - log file
If a remote program does not provide the expected results and you are using a GPIB
connection, you can log the commands and any errors that may occur. To activate the
SCPI error log function, in the "N Remote" dialog box, in the "GPIB" tab, select
"I/O Logging".
All remote control commands received by the R&S FPL1000 are recorded in log files
with the following syntax:
C:\ProgramData\Rohde-Schwarz\ZNL-FPL\ScpiLogging\ScpiLog.<xx>
where <xx> is a consecutive number, starting with 00;
A new file is created each time you stop and restart the logging function. The lowest
available number is used for the <xx> extension.
Logging the commands may be extremely useful for debug purposes, e.g. in order to
find misspelled keywords in control programs. However, remember to turn off the log-
ging function after debugging to avoid unnecessary access to the hard drive and use of
storage space.
