Handheld Spectrum Analyzers, 3.3 GHz & 8.5 GHz
Models 2650A, 2652A & 2658A
Spectrum Analyzer with Tracking Generator, 50 kHz – 3.3 GHz
Model 2652A ▲
Built-in transmission measurement
The 2652A is a 2650A with a tracking
generator added. The 2652A can be used to
rapidly determine transmission characteristics of
two-port RF devices.
Determine the gain characteristics of
an amplifier
Characterize the frequency response of an active
circuit such as an amplifier. Return loss measurement
Measure the return loss of an electric component
or circuit with a VSWR bridge Characterize the frequency response
of a filter
Measure the frequency response of a passive
component, e.g a filter, over the 2652A’s full
range of 5 MHz to 3.3 GHz.
Input (spectrum analyzer) Output (tracking generator)
Frequency range 5 MHz to 3.3 GHz
Output Level -10 dBm ± 1 dB @ 1
GHz (output level is fixed)
Output flatness ±1.5dB
Output impedance 50 Ω
Output connectors N (J)
Tracking generators are ideal for tuning filters,
determining the usable frequency range of
amplifiers and attenuators and aligning receiver
IF stages.
The tracking generator’s output frequency is the
same as the frequency the spectrum analyzer is
tuned to. This lets you see the amplitude
response of a circuit on the spectrum analyzer
screen.

APPLICATIONS
The analyzer's normalize function can be used to
remove the effects of the cable(s) connecting the
device. This allows you to differentially measure
a device's response without worrying about cable
effects.
