Front-Panel Key Reference
Meas Setup
Meas Interval
This allows you to set the number of symbols that are used in calculating the
measurement. This key is linked to the
in the Display menu.
Trig Source
Provides the menu keys that allow you to select the source for the demodulation
synchronization trigger.
Free Run
External
RF Burst
Burst Sync This specifies how the measurement will synchronize with the correct part of the
burst.
RF Amptd
None
Droop Comp Allows you to set Droop Compensation on or off. This setting is only used with
EDGE (8PSK) signals. The softkey is grayed out for non-EDGE signals.

Normalize
Normalization
displayed in dB relative to the stored
reference trace. When
the measured signal is displayed in absolute
dB.
Norm Ref Lvl Allows you to specify the reference level in
dB.
Norm Ref Posn Allows you to specify the position of the
reference trace on the display's graticule.
Position 10 refers to the top (10th) graticule
line and Position 0 refers to the bottom base
line of the graticule.
I/Q Points
The next measurement is taken immediately, capturing the
signal asynchronously (also called 'immediate').
Sets the trigger directly to an external signal connected to the
rear-panel EXT TRIG IN connector. No measurement will be
made unless a signal is connected to the EXT TRIG IN
connector on the rear panel.
Sets the measurement trigger to the leading edge of an RF Burst
signal. No measurement will be made unless a bursted signal is
being measured.
Synchronization, and hence demodulation, starts at the
beginning of the first valid burst detected. This is only
applicable to bursted radio signals such as NADC, PDC and
TETRA.
No synchronization occurs. Demodulation starts from the
beginning of the sample record.
