To prevent overlapping execution of the subsequent command before the measure-
ment has been aborted successfully, use the
*OPC
or
*WAI
command after
ABORt
and
before the next command.
To abort a sequence of measurements by the Sequencer, use the
INITiate:
SEQuencer:ABORt
command.
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. The remote chan-
nel to the R&S
ESW is blocked for further commands. In this case, you must interrupt
processing on the remote channel first to abort the measurement.
To do so, send a "Device Clear" command from the control instrument to the
R&S
ESW 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 that runs the measure-
ment.
Example: ABOR;INIT:IMM
Aborts the measurement and restarts it.
Usage: Event
HOLD
This command interrupts (holds) a scan.
To resume the scan, use
INITiate<mt>[:IMMediate]
on page 442.
Example: HOLD
Interrupts the scan.
Usage: Event
INITiate<mt>:CONMeas
This command resumes a scan that was interrupted by a transducer stop at the current
receiver frequency.
If the scan was interrupted by the
HOLD
command, you have to resume it with
INITiate<mt>[:IMMediate]
.
Suffix:
<mt>
.
INITiate1 is irrelevant.
INITiate2 resumes the scan.
