Keysight N9320B at a Glance
The Keysight N9320B spectrum analyzer is a portable, swept
spectrum analyzer with afrequency range of 9kHz to
3.0 GHz. It can be a fundamental component of an
automated system. It can also be widely used in an
electronic manufacturing environment and in
functional/final/QA test systems.
Features
The Keysight N9320B spectrum analyzer primary features
and functions are described below:
• High Sensitive Measurement
The spectrum analyzer includes an optional pre- amplifier for
signals in the frequency range up to 3 GHz, enabling more
sensitive measurements. This feature is a great help in
analysis of weaker signals.
• High Accuracy Power Measurement
The N9320B supports Keysight U2000 series power sensors
for high accuracy power measurement as a power meter.
• Power Measurement Suite
The built- in one- button power measurement suite offers
channel power, ACP, OBW, and TOI measurements.
• Spectrum Emission Mask
provides a Pass/Fail testing capability with a mask for
out- of- channel emissions measurement.
