Marker Count
While Gate is on, the Auto Rules for Sweep Type are modified so that the choice agrees with the Gate
Method: i.e., FFT for Method = FFT and Swept for Method = LO or Video
When in the ACP measurement:
–
When Meas Method is RBW or FAST, this function is unavailable, and the control is grayed-out
–
Whenever Gate is on, Meas Method, RBW, or FAST is unavailable and keys for those are grayed-
out
–
When Gate is on, Offset Res BW and Offset Video BW are ignored (if you set these values) and the
measurement works as if all Offset Res BW and all Offset Video BW are coupled with the Res BW
and the Video BW under the BW menu. When Gate is on, the Offset BW control in the Offset/Limit
menu is grayed-out

Annunciation Annunciated in the Meas Bar ; if Gate is on, the word "Gate:" followed by the gate type appears, where
–
LO = Gated LO
–
Vid = Gated Video
–
FFT = Gated FFT

Notes
In ESA, Trig Delay (On) and Gate (On) could not be active at the same time. This dependency does not
exist in PSA or in the X-Series
8.3.2 Gate View On/Off
Turning on Gate View puts the instrument into Gate View. When in Gate View, the
regular view of the current measurement traces and results are reduced vertically to
about 70% of the regular height. The Zero Span window, showing the positions of
the Gate, is shown between the Measurement Bar and the reduced measurement
window. By reducing the height of the measurement window, some of the
annotation on the Data Display may not fit and is not shown.
