Control Fields for CDMA Measurements
Trig Event
This field determines when the trigger event to the analyzer occurs.
When the selected trigger in this field is qualified by the selection in the
Qual Event field, the analyzer is triggered.
Choices
• 27 ms is an internally generated clock.
• 20 ms is an internally generated clock.
• 80 ms is an internally generated clock.
• 2 s is an internally generated clock.
• Delay controls a trigger delay timer, beginning from the positive
edge of the selected qualifier. A delay of 20 µs to 10 s is valid.
Initially, the time delay will be 100 µs.
• Immed triggers immediately after receiving the Qual Event signal.
Default selection: Immed.
