Code Domain Measurement Description

Trigger Source

Triggering choices for the Waveform Quality measurement are immediate, protocol, external, and auto. Auto
triggering is the default choice. In most cases, auto triggering provides the optimum measurement triggering
condition for the Waveform Quality measurement. For example, if the UE is synchronized to the test set,
protocol triggering is used. Immediate triggering is used if the UE is not synchronized.
When immediate triggering is used, the measurement result returned for timing error is always NAN (Not a
Number) because it is not possible to evaluate a timing error in this measurement situation.
The measurement is performed during one timeslot. The timeslot to use for the measurement is selectable (0
to 14).

Measurement Calibration

This measurement should be calibrated using the Calibrate Measurements function
("CALibration:MEASurements?" on page
last calibration. If this situation exists, the integrity indicator value becomes 19 and a message is displayed
indicating "Uncalibrated Due to Temperature".
