Set the Step Detection
Press Meas > General Setup > Average > Step Detect to set the step
Detect On and Off. When it is set to on, the filter will re-initialize
upon detection of a step increase or decrease in the measured
power to reduce the filter settling time after a significant step in
the measured power, Step detection can be set in both manual and
automatic filter modes.
Set the Measurement Gate
Press Meas > Peak Setup > Gate Setup to set the start time and gate
length for a measurement gate. A measurement gate allows
measurements to be performed on particular sections of the input
signal. The gate is defined by a start time relative to the trigger
instant and a duration. Signal samples acquired during the time
interval specified by the gate are used for the measurements in that
gate. A system of up to four independent gates is provided.
Set the Trigger
Press Meas > Peak Setup > Trig/Acq to set the trigger parameters
listed below for the measurement gate.
Acqn
Set the single, free run or continuous trigger mode.
enable trace and auto trigger delay for the single and continuous trigger
modes. For the free run mode, only auto trigger delay can be enabled.
Source
Set the trigger source to internal channel or an external
source.
Mode
Enable auto level or manually set the trigger level if the
internal trigger source is selected.
Level
sets the trigger level manually when the Mode is set to
manual.
Delay
Set the delay time to be applied between the trigger event
and all the gate start times. This allows you to time-shift all the
gates by the same amount with one setting change.
