In the “Pulse to Pulse” mode, the drift of the characteristics of the DUT over the width of a burst of pulses with one carrier frequency. For example, a powerful amplifier may amplify the first RF pulse more than subsequent ones due to heat or other effects. In this mode, in a burst of pulses with one carrier frequency and fixed power, each pulse is measured in the Point in Pulse mode. The number of pulses in a burst is equal to the specified number of sweep measurement points. A burst of pulses is generated once using a softkey, after which the RF power to the DUT is turned off to return it to its initial state. The measurement result is displayed in the time domain.

The settings for this mode are identical to those for the Point in Pulse mode, except that the center frequency is set instead of the frequency band.
