Peaking Signal Amplitude With Preselector Peak; Peaking Signal Amplitude Using Preselector Peak - HP 8590 E-Series User Manual

Peaking Signal Amplitude with Preselector Peak

Note
This application should only be performed using an HP 8592L, HP 8593E,
HP 8595E, or HP 85963.
PRESEL PEAK works above 2.9 GHz only (bands 1 through 4).
The preselector peak function automatically adjusts the preselector tracking to peak the
signal at the active marker. Using preselector peak prior to measuring a signal yields the most
accurate amplitude reading at the specified frequency. To maximize the peak response of
the preselector and adjust the tracking, tune the marker to a signal and press [AMPLITUDE),
PRESEL PEAK .
Note
PRESEL PEAK maximizes the peak response of the signal of interest, but may
degrade the frequency response at other frequencies. Use PRESEL DEFAULT or
frequency.
PRESEL DEFAULT provides the best flatness for a full single-band, for viewing
several signals simultaneously.
Example: Use the knob, step keys, or
then press CAMPLITUDE) and PRESEL PEAK . The message CAL : PEAKING appears in the active
function block while the routine is working.
