9100 SCPI Subsystems
CALibration
Used to calibrate the functions and hardware ranges of the 9100, correcting for system errors which have
accumulated due to drift and ageing effects: ........................................................................................................................ 6-25
SECure
:PASSword. Gains access to Calibration operations, using 'Cal Enable' switch and Password.
:EXIT. Permits clean exit from calibration operation ..................................................................... 6-25
TARGet
Sets up the calibration target point, hardware range (and frequency, where required). ................ 6-26
TRIGger?
Initiates the calibration at a single point, once the target and levels have been set up,
and returns '0' for pass, and '1' for fail ............................................................................................ 6-27
SPECial?
Runs the DAC characterization and returns '0' for pass, and '1' for fail ......................................... 6-27
CJUNction?
Runs the reference thermocouple junction temperature measurement
and returns '0' for pass, and '1' for fail ............................................................................................ 6-27
OUTPut
Used to control parameters associated with output connections: ........................................................................................ 6-28
[STATe] (?)
Controls output on/off switching ..................................................................................................... 6-28
COMPensation (?)
Switches the output connections for 4-wire/2-wire in impedance functions ................................... 6-28
ISELection (?)
For Current outputs, selects between front panel terminals (High currents, Current coils), and
front panel D-type Socket (Low currents) ....................................................................................... 6-29
[SOURce]
Used to select the main 9100 Function (Voltage, Current etc.), to be output: ...................................................................... 6-30

OPERation
Reads from, or writes to, the OPERation Status Register ............................................................. 6-49
QUEStionable
Reads from, or writes to, the QUEStionable Status Register ......................................................... 6-51
PRESet
Presets a default status reporting condition ................................................................................... 6-52
SYSTem
Collects general functions that are not related to 9100 performance: .................................................................................. 6-53
ERRor?
Requests the next entry from the 9100 error queue. ..................................................................... 6-53
DATE(?)
Reads or writes the present date ................................................................................................... 6-54
TIME(?)
Reads or writes the present time ................................................................................................... 6-55
SVOLtage(?)
Reads or writes the Safety Threshold Voltage in DC or AC Voltage function ................................ 6-56
VERSion?
Returns a numeric value corresponding to the SCPI version for which the instrument complies .. 6-56
