Service Equipment and Analyzer Options 8719ET/20ET/22ET
Analyzer Options 8719ES/20ES/22ES
RF Network Analyzers
Option 085, High Power System (ES Models)
This option is designed to permit the measurement of high power devices. With an
external power amplifier, this configuration will allow up to 20 Watts (+43 dBm) of output
at the test ports. The maximum test port input power is 1 Watt (+30 dBm) CW, but
jumpers on the front panel allow the insertion of high power attenuators or isolators. This
allows test device output levels up to the power limits of the inserted components.
Additionally, there is an external reference input that allows the external amplifier’s
frequency response and drift to be ratioed out, and there are internally controlled step
attenuators between the couplers and samplers to prevent overload. A network analyzer
with this option can be configured to operate as a normal instrument (with slightly
degraded output power level and accuracy) or as an instrument capable of making single
connection multiple measurements. Bias tees are not part of the signal separation
circuitry of the Option 085. Because of high output power, Option 085 is only available
with a mechanical transfer switch similar to Option 007. Option 085 also includes direct
access to the receiver (Option 012).
Option 089, Frequency Offset Mode (ES Models)
This option adds the ability to offset the source and receiver frequencies for frequency
translation measurements. This provides the analyzer with mixer measurement capability.
It also provides a graphical setup that allows easy configuration of your frequency
translation measurement.
Option 400, Four-Sampler Test Set (ES Models)
This option reconfigures the analyzer’s test set to ratio out the characteristics of the test
port transfer switch, and to include a second reference channel that allows full accuracy
with a TRL measurement calibration.
NOTE The 8722ES option 400 is optimized to operate with a test port cable length of
one meter. It may be necessary to set up the 8722ES Option 400 in the step
sweep mode if you are operating the analyzer with test port cables or
fixturing with an electronic length greater than one meter.
Option 1CP, Rack Mount Flange Kit With Handles
Option 1CP is a rack mount kit containing a pair of flanges, with handles, and the
necessary hardware to mount the analyzer in an equipment rack with 482.6 mm
(19 inches) horizontal spacing.
Option 1CM, Rack Mount Flange Kit Without Handles
Option 1CM is a rack mount kit containing a pair of flanges, without handles, and the
necessary hardware to mount the analyzer in an equipment rack with 482.6 mm
(19 inches) horizontal spacing.
