5700A/5720A Series II
Operators Manual
5-34
Table 5-2. Commands (continued)
OPER
Description
Overlapped command, ignored if not in remote.
Activates the calibrator’s output if in standby. OPER is inhibited for outputs 22V and over, if
there are faults in the fault queue (see "Fault Queue").
Parameter None
*OPT?
Description
Sequential command.
Returns a list of analog modules installed in the calibrator, including any auxiliary amplifiers
that are attached.
Parameter None
Response
(Series of strings) A list of the modules and auxiliary amplifiers, separated by commas.
Example: "5725A Attached","5215A Attached"
OUT
Description
Overlapped command, ignored if not in remote.
Sets the output of the calibrator and establishes a new reference point for shifting the output
to determine UUT error. If only one parameter is supplied, the calibrator makes the
minimum change needed to comply with the requested output. For example, if the calibrator
setting is 1V, 100 Hz and you send "OUT 2V", the setting changes to 2V, 100 Hz.
Parameters:
1. (Optional) Output amplitude with optional multiplier and unit. (At least one parameter
must be sent.)
2. (Optional) Output frequency with optional multiplier and unit. (At least one parameter
must be sent.)
Examples OUT -15.2 V (-15.2V; frequency unchanged)
OUT 188.3 MA, 442 HZ (188.3 mA, 442 Hz)
OUT 1.9 MOHM (1.9 MΩ)
OUT 100 HZ (Sets the frequency only)
OUT?
Description Sequential command
Returns the calibrator’s output amplitude and frequency (does not include multipliers).
Parameter None
Response 1. (Float) Output amplitude
2. (String) Units (V, DBM, A, or OHM)
3. (Float) Frequency (0 if dc or ohms)
Examples 1.256983E+01,V,0 (12.56983V)
1.883E-01,A,4.42E+02 (188.3 mA, 442 Hz)
1.9E+06,OHM,0 (1.9 MΩ)
OUT_ERR?
Description Sequential command.
Returns the UUT error computed by the calibrator after using the INCR command to shift
the output.
Parameter None
Response 1. (Float) UUT error magnitude
2. (String) units for the above number (PPM, PCT, or DB)
