1Overview
Agilent N9320A at a Glance
An Agilent N9320A spectrum analyzer is a swept portable
spectrum analyzer with afrequency range of 9kHz to
3.0 GHz. It can be a fundamental component of an
automated system, and be widely used in electronic
manufacturing functional/final/QA test systems.
An Agilent N9320A spectrum analyzer provides features and
functions as below:
• High sensitive measurement
The spectrum analyzer includes a pre- amplifier for signal up
to 3 GHz, enabling highly sensitive measurements. This helps
in analysis of weak signals.
• Pass/fail limits
Upper and lower limits can be set on the screen, thereby
enable the user to make PASS/FAIL judgments on trace data.
• Four-trace detection display
The spectrum analyzer displays up to four independent
traces simultaneously.
• SSB Phase Noise Measurement
The analyzer provides the automatic single- sideband phase
noise measurement capability (dBc/Hz). The display includes
frequency offset and the noise value.
• Frequency counter with 0.1 Hz resolution
The built- in counter allows the user to measure the signal
frequency with 0.1 Hz resolution.
•USBinterface
Using this interface allows the operator to save and transfer
a screen shot (in JPG format) to a USB storage device. This
feature enables measurement data to be gathered and pasted
into reports in a PC environment.
