5790A
Operators Manual
6-20
Parameter
(Optional. If omitted, the nominal amplitude is used.) A number signifying reference
amplitude (must be within a certain percentage of the expected amplitude, obtainable
using the CAL_NEXT? command.
CAL_NEXT?
Returns the value of the next point to be calibrated when in the process of calibrating a
range. Otherwise, this returns 0.0,-1.0.
Parameter
None
Response
1. (Float) The nominal amplitude of the expected value for the next calibration point.
The units are assumed to be volts. For example, if the 5790A has calibrated the
positive polarity for a dc range, the CAL_NEXT? query will return the negative of
the reference value used for the positive polarity calibration.
2. (Float) The frequency of the next point to be calibrated. The units are assumed to be
Hertz.
Example
CAL_DC 150 mV
CAL_NEXT?
-1.5E-01,0.0E+00
If the 5790A has calibrated the first point of an ac range, the CAL_NEXT? query returns
the amplitude and frequency of the next point to be calibrated (the amplitude returned is
what would be the default when doing this calibration from the front panel).
CAL_AC 150 mV
CAL_NEXT?
1.5E-01,2.0E+01
If the 5790A is not in the middle of calibrating a range, the CAL_NEXT? query returns
the values 0,0.
CAL_OFF
Cancels any interactive calibration underway (that is, one started with the CAL_AC,
CAL_DC, or CAL_I2 commands).
Parameter
None
CAL_PR
Prints a listing of a calibration report to the serial interface. (Overlapped command.)
Parameters

ABORT (Stops printing a report in progress)
•
ACTIVE (The shifts resulting from the last calibration)
•
STORED (The shifts resulting from the last stored calibration)
•
CONSTS (A list of all calibration constants)
