Use this command to calibrate the time base by GPS signal. This
command is only available with option GPS installed.
Key access: Shift > System > More > Service > Calibration > Time Base By GPS
Query Time Base Calibration Result
:SYSTem:CALibration:TBASe:FREQuency?
Use this command to query the time base calibration result.
Calibrate Amplitude By External Reference Signal
:SYSTem:CALibration:AMPLitude <dBm>
Use this command to trigger the amplitude calibration, and the <dBm>
stands for the amplitude of reference signal. The acceptable amplitude
range of reference signal is between –7 dBm and –13 dBm, and the
amplitude value used in the SCPI command must be an accurate value.
Example: :SYSTem:CALibration:AMPLitude -10.7
Key access: Shift > System > More > Service > Calibration > Amplitude >

:SYSTem:CALibration:AMPLitude:STATe?
Use this command to query the amplitude calibration result
BNC Port Input Type Setting
:SYSTem:PORT:EXTInput REF|TRIGger
:SYSTem:PORT:EXTInput?
Toggles the external input between a 10 MHz reference signal and TTL
signal.
