Handheld Spectrum Analyzers
Spectrum Analyzers
Allows you to measure the total power or
noise power in a user-specified bandwidth.
Adjacent Channel Power
Measure the ratio of power leakage (from the
wanted signal) into adjacent channels. Center
frequency, adjacent channel
bandwidth, and offset between main carrier
and adjacent channels can be set.
Two different modes are available for marker
measurements:
■ Normal marker mode measures the
frequency and level of the marked point
■ Delta marker mode measures the
frequency and level differences between
the two markers (see image below)
A dipole antenna (options M401 – M406)
connected to the RF input enables the
measurement of electric field strength.
Users can choose from 6 antennas based on
the frequency range under investigation.
Combined with the MAX HOLD function and
a 10 ms sweep time, the M404 dipole antenna
is capable of measuring the electric field
strength of Bluetooth systems and systems
using direct sequence spread spectrum/
frequency hopping modulation techniques.
Using a magnetic field probe (option PR 26M),
the 2650A series is capable of accurately
measuring the magnetic field distribution on
a PCB (printed circuit board) or IC
(integrated circuit) over a wide frequency
range of 10 MHz to 3 GHz. Since the probe’s
compensation data is already preloaded into
the analyzer, the magnetic field strength is
displayed directly in dBµA/m.
The 2650A series are straightforward to
operate and provide many functions to
facilitate quick and easy measurements:
■ Smart one button “Auto Tune" function
which automatically scans the full
frequency range, detects and centers the
maximum signal, and configures
optimum values for RBW, VBW, sweep
time and reference level
■ Input attenuator and internal preamp are
set automatically to optimal values
■ 200 setups and reference spectrum
measurements can be stored and recalled
from either internal memory or USB flash
drive
The 2650A series includes easy-to-use
software for documentation and further
analysis of your measurements. Connect
the analyzer via USB cable to your PC,
configure the analyzer remotely, then
download measurement data and
instrument settings for storage and further
analysis.
■ Continuously sweep and transfer trace
data to the PC
■ Capture 1001 trace data points (twice the
number of display dots) and store the
data in CSV format
■ Save the screen to a bitmap file
