Five Frequency Versions
The 6820 series of scalar analyzers covers the
most commonly required frequency bands in 5
versions. A comprehensive range of accessories is
available to support each of these units.
6820A series Scalar Analyzers

6825AR 10 MHz to 40 GHz Scalar Analyzer
Synthesized Source
The synthesized source has low phase noise and
1 Hz frequency resolution. VCOs are used for frequencies above 3
GHz and an integrated RF synthesizer for the 1 MHz to 3 GHz
range. Optionally increased output power is available from 3 to 24
GHz. Internal filtering results in excellent harmonic performance of
<-50 dBc (70 MHz to 24 GHz) for improved scalar measurement
accuracy. Optional step attenuators are available to set low output
powers for amplifier or receiver testing.
In CW mode the source can be used for local oscillator substitution.
A power sweep is provided for amplifier gain compression testing.
External FM can be applied by connecting an AF generator to the
rear panel. The internal modualtion option provides frequency
modulation of the source or pulse patterns for internal or external
pulse modulators. The internal pulse modulator option allows either
an external pulse generator to be connected via a rear panel BNC
connector or utilizes the pulse patterns available from the internal
modulation option. The pulse patterns may be configured and
selected in either single pulse or multi-pulse formats.
When used with the scalar analyzer the source provides a swept
synthesized output for frequency characterization of components
and systems.
Scalar Analyzer
The three input scalar analyzer provides network characterization of
components and systems. Simultaneous measurement of insertion
and return loss are displayed on the 6820 color screen. Excellent
measurement accuracy is assured by the use of EEPROM corrected
detectors.
