Introduction
The analyzer provides ultimate measurement
flexibility in a package that is ruggedized for field
environments and convenient for mobile
applications.
Functionality and Feature
The analyzer provides you with a comprehensive
functionality set and measurement convenience,
including:
• Power Measurement
provides power measurement functionality on
OBW (Occupied Bandwidth), channel power, and
ACPR (Adjacent Channel Power Ratio).
• Tracking Generator (Option TG7)
Provides an RF source for scalar network
analysis (exclusive for N9342C).
• Spectrum Monitor (Option SIM)
Provides the capability to analyze the stability of
a signal over the time. The analyzer can be used
to monitor the signal capturing performance or
intermittent events over extended periods of
time.
• High-sensitivity Measurement (Option PA7, P13, P20)
Includes a pre- amplifier, enabling highly
sensitivity measurements, this can be used to
measure the low- level signals.
•High Accuracy Power Measurement (Option PWM)
Supports Agilent U2000 series power sensors for
high accuracy power measurement as a power
meter.
• Cable & Antenna Test (Option CA7; Requires option TG7)
Provides VSWR, return loss, cable loss and
distance- to- fault measurement function.
