Notes
1. See “Burst Measurement Detector Threshold” in Chapter 4 for information
on setting the threshold for pulse measurements.
2. See “Burst Carrier Frequency Measurements” in Chapter 5 for information
on narrow pulse mode and on automatic and manual gate control for carrier
measurements.
Pulse PRI and PRF
The commands used to measure the pulse repetition interval (PRI) and pulse
repetition frequency (PRF) (Figure 3-13) of a burst signal are:
