Axis Pair
"Start Stop" lets you define the time gate via its "Start" and "Stop", "Center Span" lets
you define it via its "Center" and "Span" value (in time). The analyzer generates a
warning if the (resulting) time span exceeds the unambiguous range which is given by
Δt = 1/Δf, where Δf is the "Freq Step Size". Simply reduce the time span until the warn-
ing disappears.
Remote command:
CALCulate<Chn>:FILTer[:GATE]:TIME:CENTer
CALCulate<Chn>:FILTer[:GATE]:TIME:SPAN
CALCulate<Chn>:FILTer[:GATE]:TIME:STARt
CALCulate<Chn>:FILTer[:GATE]:TIME:STOP
Show Range Lines
Displays or hides two red lines indicating the start and stop of the time gate in a time
domain diagram.
Remote command:
CALCulate<Chn>:FILTer[:GATE]:TIME:SHOW
Bandpass / Notch
The filter type defines what happens to the data in the specific time region.
●
A "Bandpass" filter passes all information in the specified time region and rejects
everything else.
●
A "Notch" filter rejects all information in the specified time region and passes every-
thing else.
Remote command:
CALCulate<Chn>:FILTer[:GATE]:TIME[:TYPE]
Shape
Selects a gate shape which the R&S
ZNB/ZNBT uses to filter the trace in the time
domain. The drop-down list visualizes how the time gate will affect a constant function
after transformation back into the frequency domain. The selected window is applied to
the active trace. The two red vertical lines represent the "Start" and "Stop" values
defining the size of the time gate.

Side Lobe Level
Defines the side lobe suppression for an "Arbitrary Gate Shape (Dolph-Chebychev)"
gate. The entered value is the ratio of the power of the central lobe to the power of the
first side lobe in dB.
