MULT
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Multiply command) Multiplies the reference magnitude (as selected with the
EDIT
command or default to the primary output). The reference magnitude is the present
reference in either direct mode or in error mode.
Parameter: <value> (multiplier expressed as a floating point number)
Example:
MULT 2.5
Multiply the existing reference by 2.5, creating a new reference. For example, an existing
reference of 1 V is multiplied to 2.5 V.
NEWREF
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x
x
(New Reference command) Sets the new reference to the present Calibrator output value
and exit the error mode (if selected). For example, you might edit the Calibrator output
using the
EDIT
and
INCR
commands, and then use the
NEWREF
command to establish a
new reference point and exit the error mode. This is the same as pressing the Calibrator
front panel
N
key.
Parameter: (None)
Example:
NEWREF
Set the reference value to the current Calibrator output value.
OLDREF
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Old Reference command) Sets the Calibrator output to the reference value and exit the
error mode (if selected). If editing the output using the
EDIT
and
INCR
commands and
you want to return to the reference value, use the
OLDREF
command. If editing the
output and you want to make the edited value the new reference, use the
NEWREF
command.
Parameter: (None)
Example:
OLDREF
Set the output to the existing reference value, clearing editing changes.
ONTIME?
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x x
(Calibrator On Time query) Returns the time in minutes since the Calibrator was most
recently powered up.
Response: <minutes> (24-hour clock)
Example:
ONTIME?
returns
47
Returns the time since the Calibrator was last powered up: 47 minutes.
*OPC
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x
x
(Operations Complete command) Sets bit 0 (OPC) of the Event Status Register to 1
when all pending device operations are complete. Also see the
*ESR?
command.
Parameter: (None)
Example:
*OPC
Set bit 0 of the Event Status Register to 1 when all pending device operations are done.
