Trigger Enables you to configure the trigger. When using a trigger
source other than Free Run, the analyzer will begin a sweep
only with the selected trigger conditions are met. A trigger
event is defined as the point at which your trigger source
signal meets the specified trigger level.
Free Run - New sweep starts as soon as possible after the
current sweep ends.
RF Trigger - Activates the trigger condition that starts the
next sweep if the detected RF envelope voltage rises to a
level set by the RF trigger level.
Ext Rise/Fall - Activates the trigger condition that will start
a sweep when the external voltage passes through 2 volts.
The external trigger signal must be a 0 V to +5 V TTL signal.
Sets the trigger polarity to positive/negative.
Trig Delay - Allows you to set and turn on or off a delay,
during which the analyzer will wait to begin a sweep after
receiving an external trigger signal.

Limits Set a limit value to warn you if the measured value exceeds
the value specified here. The test reuslt will be in purple if
this reslut exceeds the corresponding limit value.
Limit - Turns on/off the limit function
CarrPow Upr - Sets the carrier power upper limit
FreqDev Up/Low - Sets the frequency deviation upper/lower
limit
CarrFreOff Up - Sets the carrier frequency offset upper limit

Sweep Togglese the sweep type between single and continuous in
AM/FM mode. When this softkey is set to Single, press the
next Single softkey to execute a new sweep as soon as the
trigger condition is met.
