Handheld Spectrum Analyzers
Spectrum Analyzers
The 2650A series handheld spectrum
analyzers are compact, lightweight, and
cost-effective instruments for quick and
precise signal investigations. At a weight of
only 4 lbs (1.8 kg), the 2650A series are by far
the lightest full-featured spectrum analyzer
available, yet they deliver performance and
features comparable to full-size bench
spectrum analyzers and can operate up to
4 hours on a single battery.
With their ease of use, measurement
flexibility, and unmatched portability, the
2650A series analyzers are indispensable
tools for engineers and technicians who con-
duct field measurements in the 50 kHz to 8.5
GHz range.
Applications
■ Installation, maintenance, and
troubleshooting of wireless
communication systems such as
W-CDMA/CDMA, GSM, WLAN, WiMAX
and Bluetooth
■ Detection of signal interference and
undesired emissions
■ TV and broadcasting
■ Antenna alignment
■ Electric field strength measurement with
dipole antennas optimized for typical
frequencies used in wireless systems
■ Magnetic field strength measurement
with magnetic field probe (PR 26M)
■ Frequency response measurements of
passive components such as RF cables,
filters, and attenuators using the built-in
tracking generator (2652A)
Features & Benefits
■ Frequency range from 50 kHz – 8.5 GHz
■ Truly portable spectrum analyzer
weighing only 4 lbs (1.8 kg) including
the battery
■ Impressive 4 hour battery life;
easy-to-replace rechargeable
Lithium-Ion battery
■ USB interface for PC connectivity
■ Intuitive PC software for remote
control and documentation of
measurement results
■ Conveniently store measurement
results and screenshots in bitmap
format to USB flash drive (USB host
interface)
■ Large easy-to-read color display
■ Measurement functions: channel /
adjacent channel power, occupied
bandwidth, electric and magnetic field
strength
■ Convenient Auto Tune function
automatically sets center frequency to
the maximum signal within full span
and optimum settings for RBW, VBW
and sweep time
■ External trigger for zero span
measurements
■ SCPI-like remote control commands
Superb performance improves your
productivity
Advanced synthesizer-based design
enables the 2650A series to provide you with
an accurate and detailed picture of the spec-
trum you are investigating.
