On Uses only the specified range of captured data in results calculation. In the Magnitude Capture
Buffer trace, two vertical lines mark the specified range.
Off Uses all the captured data in results calculation.
In the "Gate Settings" dialog box, the following parameters are set:
Delay Start point of captured data to be used in results calculation, i.e. the delay from the start of
the captured data in time or samples. If the delay is specified in time, the number of sam-
ples is updated accordingly, and vice versa.
Length Amount of captured data to be used in results calculation. If the length is specified in time,
the number of samples is updated accordingly, and vice versa.
Mode Sets the type of triggering (level or edge) by the external gate signal.
Link Gate and
Mark
If activated, the position of the marker and the gate lines are linked. The marker is posi-
tioned half way between gate start and end. The marker position alters when the gate is
modified, and the gate lines move with the marker when the marker position is altered.
The gate settings are defined for following measurements: PVT, Spectrum FFT, CCDF,
Spectrum Mask, Spectrum ACPR.
If a frequency sweep measurement is active (Spectrum Mask and Spectrum ACP) the
result display is switched to the Magnitude Capture Buffer display in order to allow the
gate to be set the correct part of the sweep.

Import ← PVT
Opens the "Choose the file to import" dialog box.
Select the IQ data file you want to import and press ENTER. The extension of data
files is *.iqw.
This function is not available while a measurement is running.

Export ← PVT
Opens the "Choose the file to export" dialog box.
Enter the path and the name of the I/Q data file you want to export and press ENTER.
The extension of data files is *.iqw. If the file cannot be created or if there is no valid
I/Q data to export an error message is displayed.
This function is not available while a measurement is running.
