Adding an Option
Pressing [System] > {More} > {Service} > {Add Option}
brings up a dialog box for entering the option
license code. Use the numeric keypad to input the
option license code and then use the [ENTER] key as
a terminator. If the analyzer recognizes the option
license code, a message “Option activated

[–350, Query overflow]. For more information,
refer to “Error Messages" on page 143.
Perform Calibration
The N934xC provides three manual calibration
function to calibrate the time base and amplitude.
The analyzer should warm up for 30 minutes
before calibration.
Time Base Calibration
Perform a time base calibration to guarantee the
frequency accuracy.
When the calibration function is triggered, the
current measurement is interrupted and a gauge
displays on the LCD. A message will display on the
LCD which indicates the calibration is finished,
and the interrupted measurement restarts.
Please refer to the operation procedures below:
