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.

Gate View On/Off
Turning on Gate View in the Swept SA measurement provides a single-window gate view display..
Turning on Gate View in other measurements shows the split-screen Gate View. In these measurements,
when the Gate View is on, 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.

Dependencies In the Swept SA measurement:
In Gate View, the regular Acq Time key is grayed out . When pressed, the grayed out key puts up the
informational message "Use Gate View Sweep Time in the Gate menu."
In the other measurements:
When you turn Gate View on, the lower window takes on the current state of the instrument. Upon
leaving Gate View, the instrument takes on the state of the lower window.
When you turn Gate View on, the upper window Acquisition Time is set to the gate view acquisition
time.
Couplings These couplings apply to the Swept SA measurement:
•
When Gate View is turned on, the instrument is set to Zero Span.
•
Gate View automatically turns off whenever a Span other than Zero is selected.
•
Gate View automatically turns off if you press the Last Span key while in Gate View, and the
instrument returns to the Span it was in before entering Gate View (even if that is Zero Span).
•
When Gate View is turned on, the sweep time used is the gate view sweep time. This is set
according to the rules in section
"Gate View Setup " on page 1571
•
When Gate View is turned off, Sweep Time is set to the normal Swept SA measurement sweep
time.
