Command Parameters / Remarks Short Description
*OPT?
OPTion identification
query
–
query only
Queries the options included in the instrument and returns a list of the options
installed. The response consists of arbitrary ASCII response data according to
IEEE 488.2. The options are returned at fixed positions in a comma separated
string. A zero is returned for options that are not installed.
The OPT information is editable; see "Define *IDN + *OPT..." on page 619.
*PCB
Pass Control Back
0...30 / no query Indicates the controller address to which GPIB bus control is returned after ter-
mination of the triggered action.
*PRE
Parallel poll Register
Enable
0...255 Sets parallel poll enable register to the value indicated. Query *PRE? returns
the contents of the parallel poll enable register in decimal form.
*PSC
Power on Status
Clear
0 | 1 Determines whether the contents of the ENABle registers is maintained or reset
when the instrument is switched on. *PSC = 0 causes the contents of the status
registers to be maintained. Thus a service request can be triggered on switch-
ing on in the case of a corresponding configuration of status registers ESE and
SRE. *PSC = 0 resets the registers. Query *PSC? reads out the contents of the
power-on-status-clear flag. The response can be 0 or 1.
*RST
ReSeT
– / no query Sets the instrument to a defined default status. The command is equivalent to
SYSTem:PRESet[:DUMMy]
. The *RST value of each command is reported in
the reference description. See also
SYSTem:PRESet:SCOPe
.
*SRE
Service Request
Enable
0...255 Sets the service request enable register to the value indicated. Bit 6 (MSS
mask bit) remains 0. This command determines under which conditions a ser-
vice request is triggered. The query *SRE? returns the contents of the service
request enable register in decimal form. Bit 6 is always 0.
*STB?
STatus Byte query
– / query only Reads the contents of the status byte in decimal form.
*TRG
TRiGger
– / no query Triggers all actions waiting for a trigger event. *TRG generates a manual trigger
signal. This common command complements the
TRIGger...
commands of
the analyzer.
*WAI
WAIt to continue
– / no query Prevents servicing of the subsequent commands until all preceding commands
have been executed and all signals have settled.
