4.12.4 Status Subsystem
This subsystem controls the SCPI-defined status reporting structures, which are the QUEStionable and
OPERation status registers, and the error/event queue. The QUEStionable and OPERation status
registers are mandated by SCPI, and so are implemented, but are not used by the hardware. No status
is ever reported through them, and they are not detailed in this manual. The following shows the
STATus structure used:
:STATus
:PRESet
:QUEue
[:NEXT]?
4.12.4.1 Status Preset
This command is used to set certain status values to defined values.
- The OPERation and QUEStionable enable registers are cleared.
- The Positive transition filters are set to 32767.
- The Negative transition filters are set to 0.
Since the Questionable and Operation status registers are not used in the model 4033 and 4034, the
PRESet command has no real effect.
COMMAND TYPE: Setting only
SETTING
Syntax: :STATus:PRESet
4.12.4.2 Error Queue Read
This query returns the first entry in the error queue and removes that entry from the queue. Its function
is identical to that of the :SYSTem:ERRor? query.
COMMAND TYPE: Query only
QUERY
Syntax: :STATus:QUEue[:NEXT]?
Response: <error number>,
“<error description>“
4.12.5 System Subsystem
The SYSTem subsystem collects the functions that are not related to instrument performance. The
functions implemented in the pulse generator are security, GPIB address changing, error queue reading,
SCPI version reading, and power-on buffer setting (not SCPI-defined). The command structure is as
follows:
:SYSTem
:COMMunicate
:GPIB
:ADDRess <numeric value>
:ERRor?
:VERSion?
:SECurity
[STATe] <Boolean>
:POBuffer <numeric value>
