8.4 Performing Measurements
The following commands are necessary to perform measurements.
You can also perform a sequence of measurements using the Sequencer (see "Multi-
ple Measurement Channels and Sequencer Function" on page 9).
ABORt............................................................................................................................ 80

ABORt
This command aborts the measurement in the current measurement channel and
resets the trigger system.
To prevent overlapping execution of the subsequent command before the measure-
ment has been aborted successfully, use the *OPC? or *WAI command after ABOR and
before the next command.
For details see the "Remote Basics" chapter in the R&S FSW User Manual.
Note on blocked remote control programs:
If a sequential command cannot be completed, for example because a triggered sweep
never receives a trigger, the remote control program will never finish and the remote
channel to the R&S FSW is blocked for further commands. In this case, you must inter-
rupt processing on the remote channel first in order to abort the measurement.
To do so, send a "Device Clear" command from the control instrument to the
R&S FSW on a parallel channel to clear all currently active remote channels. Depend-
ing on the used interface and protocol, send the following commands:
●
Visa: viClear()
●
GPIB: ibclr()
●
RSIB: RSDLLibclr()
Now you can send the ABORt command on the remote channel performing the mea-
surement.
Example:
ABOR;:INIT:IMM
Aborts the current measurement and immediately starts a new
one.
