Description This appears in two locations: the POWER Tracking
and the USER CAL Tracking Menu. The operation is the same in
both locations.
This causes the synthesizer, when in CW or manual-sweep
output mode, to align the output filter (SYTM) so that its
is centered on the RF output. Peaking is used to obtain both the
maximum available power and spectral purity, and the best pulse,
FM envelopes, at a given frequency. This peaking occurs each time
the frequency is changed, or every seven minutes. An asterisk next to
the key label indicates this function is active.
Programming Codes SCPI: CALibration:PEAKing:AUTO
