20 Keysight N9010A EXA Service Guide
Overview
Signal Analyzer Accessories
— The Keysight 85905A CATV 75 ohm preamplifier provides a minimum of
18 dB gain from 45 MHz to 1 GHz. (Power is supplied by the probe power
output of the analyzer.)
— The 11909A low noise preamplifier provides a minimum of 32 dB gain from
9 kHz to 1 GHz and a typical noise figure of 1.8 dB.
RF and Transient Limiters
The Keysight 11867A and N9355C RF Limiters protect the analyzer input
circuits from damage due to high power levels. The 11867A operates over a
frequency range of DC to 1800 MHz and begins reflecting signal levels over
1 mW up to 10 W average power and 100 watts peak power. The N9355C
microwave limiter (0.01 to 26.5 GHz) guards against input signals over
10 milliwatts up to 1 watt average power.
The Keysight 11947A Transient Limiter protects the analyzer input circuits from
damage due to signal transients. It specifically is needed for use with a line
impedance stabilization network (LISN). It operates over a frequency range of
9 kHz to 200 MHz, with 10 dB of insertion loss.
Power Splitters
The Keysight 11667A/B/C power splitters are two-resistor type splitters that
provide excellent output SWR, at 50 Ω impedance. The tracking between the
two output arms, over a broad frequency range, allows wideband
measurements to be made with a minimum of uncertainty.
11667A: DC to 18 GHz
11667B: DC to 26.5 GHz
11667C: DC to 50 GHz
