Select Display (Display Zone submenu)
See 2.2.4 Display Zone for standard selections.
Select View
Select the slot(s) to view. Although slots are approximately 14.167 milliseconds (i.e. 1.02 seconds per
multiframe of 18), the profile for a slot is 14.778 ms, divided into three regions for ramp-up (0.889 ms),
burst (13.056 ms), and ramp-down (0.833 ms).
Slot 1 – Horizontal axis 0 ms to 14.78 ms with slot from 0 to 14.167 ms.
Frame – Horizontal axis 0 ms to 57.278 ms with 4 slots starting at 0 ms. See Figure 2.2.7.7-5.
Note: Ramp down time for a slot overlaps the adjacent slot by 0.611 milliseconds.
Vertical Maximum
Adjusts the maximum level for the vertical scale of the display (top line) from -120 dBm to +60 dBm in
1 dB increments.
Vertical Scale
Selects the vertical scale resolution for the display’s major grid lines from 1 dB/div to 10 dB/div via a
horizontal soft key list.
Display Mode
Selects the display presentation with the following horizontal menu choices:
Normal – The display updates continuously.
Freeze – Provides a snapshot of the current display indication and stops additional updates.
Max Hold – The display retains the highest peak signal amplitudes measured during successive sweeps.
Average – The displayed signal amplitudes are a rolling average of the peak amplitudes measured on each
successive sweep. The average consists of 1 to 5 sweeps, shown beside the mode indication. See Figure
2.2.7.7-4.
Marker Mode
Provides display marker control via a horizontal soft key menu. Markers can be turned off or on with a
choice of numeric readout for the signal measurements. “Absolute” provides actual peak readings while
“Delta” measures the relative difference of both power and time between the markers. See Figure
2.2.7.7-5.
Toggle Marker
Cycles through the available markers to select the active one (yellow) for positional adjustment on the
display. The active marker is moved using the Left/Right (◄►) cursor control buttons.
