50 MHz Amplitude Reference Measurement
This aligns the internal 50 MHz reference signal to an external
reference signal that you supply. You must be in the Service mode to use
these commands. Use INSTrument:SELect to set the mode.
The general functionality of CONFigure, FETCh, MEASure, and READ
are described at the beginning of this section. See the
SENSe:AREFerence commands for more measurement related
commands.

Remarks: For auto adjustment of the internal 50 MHz amplitude
reference, use
