Front-panel key access:
Allows you to enter the period (cycle time) of the burst
BURST PERIOD
RF signal. The cycle time is needed to set sweep times.
Front-panel key access:
Allows you to enter the pulse width ("on" time) of the
BURST WIDTH
burst RF signal. The pulse width is needed in the gated
method to set gating times. It is also needed in the
burst power method.
Front-panel key access:
BURST PWR METHOD
measurements measuring peak transient, peak
random, and average power. This method performs a
measurement and computation to find the impulsive
and random powers similar to the two-bandwidth
method (2BW METHOD), but using a different and
faster technique.
It also uses an rms-responding technique to compute a
true power ratio between the main and adjacent
channels, without peak weighting or assumptions
about phase relationships.
Front-panel key access:
Accesses the bandwidth functions menu: RES BW

Front-panel key access:
Displays all menus related to calibration and diagnostic

routines.
Front-panel key access:
Activates a procedure to store the average of an open
CAL OPN/SHRT
and a short calibration into trace B and into the
nonvolatile memory of the spectrum analyzer (this
average is stored in spectrum analyzer memory for
future reference). When activated, the message
Connect OPEN. Store when ready. appears in the
active function block. Once the open is connected, press
STORE OPEN. Connect SHORT. Average with open
when
ready. will then appear in the active function block.
Connect the short, then press AVERAGE SHORT. The
state of the open/short average trace is stored in state
register number 8.
