The Level section defines the trigger thresholds if the measurement is triggered by the RF Power or IF Power (see Source) respectively. Both thresholds are defined relative to the maximum input level set in the Analyzer tab (see RF Max. Level softkey). The Level settings have no influence on Free Run or External trigger measurements.
Note:
The trigger levels are always relative to the current maximum input
level. If RF Max. Level is set manually (RF Mode = Manual),
the current input level is constant and equal to the setting value. In
autoranging mode (RF Mode = Auto), the current maximum input level
is dynamically adapted to the measured RF input level; the trigger levels
change accordingly.
The RF Power trigger threshold is the RF input signal level (Wideband Power) beyond which the trigger condition is satisfied and a measurement is initiated.

Medium High |
Low trigger threshold, equal to approx. the RF Max. Level
–26 dB.
Medium trigger threshold, equal to approx. the RF Max. Level –16 dB. High trigger threshold, equal to approx. the RF Max. Level –6 dB. |
The IF Power trigger threshold is the IF trigger signal level beyond which the trigger condition is satisfied and a measurement is initiated. The IF Power input value defines the trigger threshold relative to the maximum input level:
IF power trigger threshold = <RF Max. Level> + <IF Power>
