—Amplifier
—Downconverter
—Upconverter
— Multi-Stage Converter
Refer to “Using Measure Setup to Choose DUT Type” on page 410.
Each of the four measurements has frequency context and loss compensation
softkeys that can used to optimize the DUT’s noise figure measurement. Refer
to “DUT Type and Frequency Context” on page 415 and to “DUT Type Loss
Compensation” on page 420.
