Refurbished
Option 085, high power system
This option is designed to permit the measurement of high power amplifiers at RF levels up to 20 Watts
(+43 dBm), with full two-port calibration. A switch is added to the reference path so that booster
amplifier response can be ratioed out. To protect the analyzer from high power levels, this option
allows the addition of isolators at both test ports and includes internally controlled step attenuators
between couplers and samplers. Bias tees, isolators and booster amplifiers are not included. Network
analyzers with option 085 can also be configured to operate as standard instruments with degraded
power accuracy or as instruments capable of making single connection multiple measurements.
Option 012, direct access receiver configuration
This option provides front panel access to the A and B samplers for improved receiver sensitivity.
Option 012 improves signal-to-noise in free space materials measurements with the use of multiple
antennas. Direct connection of the reflection antennas to the A and B samplers eliminates internal reflections of the transmitted signal in the
reflection path, improving the signal to noise ratio. Option 012 also allows you to add attenuators
between the couplers and samplers, increasing the power handling capability of the instrument.
