8 Channel Power Measurement
Sweep/Control
Pause
Pauses a measurement after the current data acquisition is complete. When Paused, the label on the key
changes to Resume. Pressing the Resume key resumes the measurement at the point it was at when
paused. See Pause/Resume for more details.

Initial S/W Revision Prior to A.02.00
Gate
Accesses a menu that enables you to control the gating function. The Gate functionality is used to view
signals best viewed by qualifying them with other events.
Gate setup parameters are the same for all measurements – they do not change as you change
measurements. Settings like these are called “Meas Global” and are unaffected by Meas Preset.

Readback
The state and method of Gate, as [Off, FFT] or [On, FFT]. Note that for measurements that only
support gated FFT, the method is nonetheless read back, but always as FFT.
Initial S/W Revision Prior to A.02.00
Gate On/Off
Turns the gate function on and off.
When the Gate Function is on, the selected Gate Method is used along with the gate settings and the
signal at the gate source to control the sweep system with the gate signal. Not all measurements allow
every type of Gate Methods.
When Gate is on, the annunciation in the measurement bar reflects that it is on and what method is used,
as seen in the following "Gate: FFT" annunciator graphic.
