Key Function Descriptions
Key Descriptions
The gate function requires a gate trigger signal be
connected to the rear panel. If the gate is turned on
without a signal present, operating other functions like
signal tracking, signal identification, frequency count,
or preselector peaking may cause the spectrum
analyzer to stop functioning until it is powered on
again.
Front-panel key access:
SWEEP
GATED METHOD Makes adjacent channel power (ACP) measurements
of transient and random peak power using
time-selective gating techniques. A TTL-type trigger
signal must be applied to the spectrum analyzer when
using this method. This method is the same as the two
bandwidth method (2BW METHOD) except that the
random and impulsive powers are separated using a
different technique. Gated video techniques are used to
allow a response to just the peak of the random part of
the adjacent channel power. The impulsive part of the
power is found by the power difference between an
ungated measurement and a gated measurement. This
method supports TIA/EIA IS-54 NADC-TDMA
measurements.
Front-panel key access:
MEAS/USER
GATED VIDEO Accesses the menu of functions for setting gate
parameters.
Front-panel key access: SWEEP
HOLD Clears the active function area and the current softkey
menu from the display, and expands the display
horizontally to the full width of the screen. The width of
the trace and graticule increase to occupy the resulting
blank space. The current active function is held at a
constant setting until another function is activated.
Front-panel key access:
HOLD
IF ADJ ON OFF Allows you to turn the automatic IF adjustment ON or
OFF. This function is normally ON. When IF ADJ ON
OFF is ON, various parameters in the IF are adjusted
during the retrace time of the sweep. Several minutes
and several sweeps may be required to complete a cycle
of all the adjustments. In single sweep mode, a small
portion of the IF adjustment will be done at the end of
each sweep and approximately every two seconds
afterward while the spectrum analyzer waits for a
trigger.
