1. Measured at –5 dBm test port power.

2. Pulse input connectors are operational only with Option H08 (Pulsed Measurement Capability) enabled.

3. Based on deviation from signal reduction equation:

Signal Reduction (dB) = 20log

(Duty_cycle) = 20log

(pulse_width/pulse_repetition_interval).

Measured at pulse repetition frequency of 1 MHz.
