If a handoff waveform quality measurement is attempted while in active cell operating mode, a call must be connected so that long code information can be obtained from the mobile station and measurement triggers can be synchronized to the CDMA frame clock inside the test set.
A radio configuration 3 (F3R3), radio configuration 4 (F4R3) or radio configuration 5 (F5R4) call must be connected.
The START SINGLE key initiates a handoff waveform quality measurement from the front panel (see Measuring Handoff Waveform Quality for manual measurement instructions).
If the Access Probe Power measurement is currently selected and the Trigger Arm setting is Continuous, all other measurements are disabled. Use the SETup:CAPPower:CONTinuous command to set the trigger arm state to single and retry this measurement.
The test set receiver's expected signal amplitude and channel number (or frequency) must be set up correctly for accurate measurements. This is normally done automatically (see Active Cell Operating Mode ) but can also be done manually (see Receiver Control ).
When the handoff waveform quality measurement is running, changing
PLCM Type
causes the measurement aborted and restarted. See
PLCM Type
for details.
An integrity indicator of 17 (Can not correlate), indicates that the received signal did not correlate with an internally generated reference signal. See Integrity Indicator .
