How to Use DUT Measurement Setups
Noise figure Option 356 has four predefined measurement setups:
—Amplifier
—Downconverter
—Upconverter
— Multi-Stage Converter
Refer to
“Using Measure Setup to Choose DUT Type” on page 690.
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 700 and to “DUT Type Loss
Compensation” on page 705.
Using Measure Setup to Choose DUT Type
This section contains the following:
—Setting
DUT > Type [Amplifier], see Figure 29-11 on page 692 and for
Smart Noise Source, see
Figure 29-15 on page 696.
—Setting
DUT > Type [Downconverter], see Figure 29-12 on page 693 and
for Smart Noise Source, see Figure 29-16 on page 697.
