Internal 50 MHz Amplitude Reference Alignment Control
:CALibration:REF50:ANOW
Immediately does the automatic alignment of the internal 50 MHz
amplitude reference oscillator. This command is used with the
interactive mode of the 50 MHz alignment, i.e. CAL:REF50:ENTer.
Remarks: You must be in the Service mode to use this command.

Internal 50 MHz Amplitude Reference Alignment Control
:CALibration:REF50[:DOIT]
:CALibration:REF50[:DOIT]?
Does automatic alignment of the internal 50 MHz amplitude reference
oscillator. You do this by setting an external source to
−25.00 dBm and
using a power meter to measure the exact value. Then use
CAL:REF50:AMPL to input the source amplitude, measured on the
power meter. Finally, connect the source to the instrument RF INPUT
port and run the adjustment.
Remarks: You must be in the Service mode to use this command.
Use INSTrument:SELect.
