Calibration Description
Perform the verification tests before calibrating your power analyzer. If the power
analyzer passes the verification tests, the unit is operating within its calibration limits
and does not need to be re-calibrated.
The Keysight N6705C DC Power Analyzer 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.
The correct password is required to enter the Admin menu, which contains the calibration function.
l
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
for more information.
Calibrate only ONE channel at a time. The calibration commands accept only a single channel
l
number for the channel parameter. Calibration cannot be performed on channels that have been
grouped. If any channels have been grouped, they must be ungrouped before they can be cal-
ibrated.
When calibrating the unit using SCPI commands, most steps involve sending a *OPC? query to syn-
l
chronize with the power analyzer'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.
When calibrating the unit using SCPI commands, most steps involve sending a *OPC? query to syn-
l
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 analyzer must be taken into account. Use "Wait" statements to allow
for the appropriate settling times for the power analyzer.
