Calibration Description
Perform the verification tests before calibrating your power system. If the power system
passes the verification tests, the unit is operating within its calibration limits and does
not need to be re-calibrated.
The Keysight N6700C series MPS features closed-case electronic calibration; no internal mechanical
adjustments are required. The instrument calculates correction factors based on input reference
values that you set and stores correction factors in non-volatile memory until the next calibration
adjustment is performed. This EEPROM calibration memory is not changed by cycling power or *RST.
l The correct password is required to enter the Admin menu, which contains the calibration function.
The password is factory-set to 0 (zero). You can change the password once calibration mode is
entered to prevent unauthorized access to the calibration function. Refer to Password Protection
for details.
l Calibrate only ONE channel at a time. The calibration commands accept only a single channel
number for the channel parameter. Calibration cannot be performed on channels that have been
grouped. If any channels are grouped, they must be ungrouped before they can be calibrated.
l When calibrating the unit using SCPI commands, most steps involve sending a *OPC? query to syn-
chronize with the power system’s command completion before proceeding. The response from the
instrument must be read each time *OPC? is given. In some steps, it may take up to 30 seconds for
*OPC? to respond.
l When calibrating the unit using SCPI commands, most steps involve sending a *OPC? query to syn-
chronize with the instrument’s command completion before proceeding. The response from the
instrument must be read each time *OPC? is given. Additionally, the relatively slow settling times
and slew rates of the power system must be taken into account. Use "Wait" statements to allow
for the appropriate settling times for the power system.
