1. Measured at –5 dBm test port power.
. Pulse input connectors are operational only with Option H08 (Pulsed Measurement Capability) enabled.
. Based on deviation from signal reduction equation:
Signal Reduction (dB) = 0log

(pulse_width/pulse_repetition_interval).
Measured at pulse repetition frequency of 1 MHz.
