Command Effect Programming of controller
*OPC
Sets the Operation Complete bit in the ESR
after all commands sent prior to *OPC have
been processed.
Set bit 0 in the ESE of the R&S NRP2.
Set bit 5 in the SRE of the R&S NRP2.
Wait for service request (SRQ).
*OPC?
Writes 1 in the output buffer after all com-
mands sent prior to *OPC? have been pro-
cessed.
IEC/IEEE bus: the R&S NRP2 is addressed
as a talker.
*WAI
Commands can be sent but they are only exe-
cuted after completion of all commands sent
prior to *WAI.
Dividing commands timewise before/after
*WAI serializes the command sequence.
*WAI is sent directly after the command that
should be completed before other com-
mands can be executed.
5.9 Automatic Settings for Manual Selection of a Measure-
ment Mode
When the measurement mode of a sensor is manually selected ("Sensor"→"Mode"),
automatic settings are made for the trigger system and timing, which cannot be changed
by manual control. This considerably simplifies operation. These settings are not changed
when the measurement mode is selected by remote control (SENSe:FUNCtion) and
have to be set to the desired value by appropriate SCPI commands.
The following table lists the respective setting capabilities and the values that are auto-
matically set in manual control.
