Pwr Ramp: Pulse (Option 006 Only)
4. Meas Sync (Sync
Status)
This field displays any errors that occurred while trying to synchronize to the
demodulated data.

5. Pulse On/Off Fall This field displays the measured amplitude at the fall-position time relative to the
average On power over the useful bits in the measured burst.

METER, Units
NOTE The Pulse On/Off Ratio measurement requires the use of measurements on three
bursts: the first is to establish the reference amplitude level of the burst, the second is
to measure the rise portion of the burst, and the third is to measure the fall portion of
the burst. Between the measurements the analyzer amplitude and trigger delay is
internally changed for the following measurement. Since RF Rise triggering is based
on a variable rising edge of the incoming signal, the measurement result cannot be
considered valid, unless the burst timing is consistent.
NOTE When the Test Mode or CW Generator mode is selected on the cell control screen,
the RF rise trigger is automatically selected.
6. Pulse On/Off Rise This field displays the measured amplitude at the rise-position time relative to the
average On power over the useful bits in the measured burst.

7. Rise Pos This field selects the time (relative to the center of bit zero) that the amplitude on the
amplitude envelope will be measured.
Range −56.0 µs to 0.0 µs.
8. Single/Cont Single allows one test to be performed. Cont allows testing to automatically repeat.
