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 result will be in purple if this result
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
ASK/FSK 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.
