Update rate (transition time between
pulses in streaming)

1. For streaming mode only. Update rate refers to the transition time from the finishing of the leading pulse to the phase and amplitude settled in the following
pulse. The diagram in N5194A section doesn’t apply.
2. The N5192A does not have specified phase repeatability.

1. Maximum CW power specifications are warranted from 15 to 40 ˚C. Maximum power in the 40 to 50 ˚C temperature range typically degrades less than 1 dB.
2. Instrument specifications are based on max specified power, unless otherwise stated. When operating at max available power, spectral purity will be
degraded.
