6824A 10 MHz to 24 GHz Scalar Analyzer
6825A 10 MHz to 46 GHz Scalar Analyzer
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.
Bandpass filter insertion loss measurement
Each detector is individually characterized for linearity and
frequency response to provide a measurement accuracy close to that
achieved with a power sensor. A range of autotesters with high directivity is available for return loss measurements.
Fault Location
Fault location software is standard on all 6820A series instruments.
Many modern communication systems rely on a coaxial or waveguide
feed between the transmitter and antenna. The fast fault location
facility of the 6820A can quickly locate the position of faults causing
poor return loss in the feed, which can seriously impact system performance.
Measurement resolution and accuracy is assured by the use of a synthesized source with up to 1601 measurement points.
Fault location measurement of a coaxial feed and antenna
Simplified User Interface
Integration of the source and scalar analyzer, and the built-in applications facility, makes operations faster and simpler. The operator uses
a single interface to set up any measurement. This saves time and is
easier than writing software to perform comprehensive network
measurements.
Eight softkeys give rapid access to all commonly used parameters.
Softkeys are shaped to inform the user of the action that the key will
perform, e.g. enter data, select from list, move to another menu or
immediate action. All commonly accessed functions are no more than
one level deep, so that the instrument operation is easily learned.
Applications Interface
An applications interface is built into the 6820A series which allows
the user to create their own measurement routines and guide the
operator through the test procedure. For example it can display on the
6820A screen how to set up the measurement, lead the operator
through a calibration, show where to connect the device under test
and then test the device’s performance against predefined limits. The
applications facility can reduce the incidence of operator error,
improve measurement repeatability, provide guidance to infrequent
users or simplify complex test procedures.
Color Display
A large TFT color display is fitted to the 6820A displaying up to four
measurements on two channels. Scalar measurements can be
displayed simultaneously on independent channels.
Dual channel display, showing wide band and narrow band fre-
quency sweeps
Comprehensive Markers
Up to eight markers are available. The marker menus provide the
tools that are most commonly used in each of the measurement
modes.
In scalar mode markers automatically calculate peak to peak ripple,
N-dB bandwidth, -1 dB bandwidth and find maximum and minimum
signal levels. This simplifies device characterization and reduces test
time.
For fault location measurements the next peak left/right feature
identifies the position and magnitude of each of the discontinuities
along the transmission line. The peak find softkey quickly locates the
biggest discontinuity on the line.
Fast Field Repair
6820A has a modular architecture with modules slotted onto a
common mother board. In the event of a module failure the instrument can be repaired by module replacement to reduce instrument
downtime. Following a repair, software routines realign the replaced
module.

Manufacturing Test
To the production manager the 6820A offers reduced programming
time, reduced test time and simplified archiving of results. 6820A is
fully compliant with the IEEE 488.2 GPIB standard. A full 401 data
points can be transferred over the GPIB in typically <50 ms.
Individual data points can be repetitively read in typically 10 ms. This
enables full results archiving with minimal time penalty.
Continuity of test is essential in a production environment. A failed
test system can result in expensive loss of output. 6820A with its field
replaceable modules minimizes any output loss due to test system
failure.
Installing and Maintaining Systems
During the installation period of a microwave system it is always necessary to revalidate key parameters. 6820A provides a comprehensive
solution for installation teams. It is housed in a ruggedized case, has
secure handles and can be supplied with a protective carrying case.
For systems with long waveguide or coaxial feeds the 6820 is used by
the installation team to measure return loss and if necessary fault
location. The synthesized source with 1601 measurement points
ensures precise fault location measurements. AC Detection can be
used for return loss and fault location measurements in the presence
of interfering signals, a common cause of poor measurement performance in the field. In this mode the source output is chopped and
the resulting pulsed signal is demodulated and processed in such a
way that interference and zero drift are effectively cancelled.
By archiving results to external USB Flash Memory, or the internal
instrument memory, the 6820A forms the basis of a preventative
maintenance system. Experience shows that degradation in the
antenna feed is the major source of system field failures. 6820A has
the accuracy to monitor and identify gradual system degradation with
time.
Additionally, the synthesized microwave source may be used in conjunction with the optional step attenuators, to carry out system sensitivity tests. The internal pulse modulator and modulation options
with both single pulse and multi-pulse capability offers the ability to
perform tangential sensitivity and range tests for many different types
of radar systems
Results Logging and Outputting
Measurement results can either be saved to internal non-volatile
memory or to USB Flash Memory. Traces saved vis USB can then
be archived or imported into a spreadsheet for viewing.
