Example: Typical Noise Figure Measurement Procedure

This section briefly reviews the steps in setting up a noise figure measurement.
If you are not familiar with this process or would like more information, refer to
"Overview of Softkey Menus" on page 657
Measurement Setups" on page
1. Set up a Noise Source ENR Table:
2. Set the resolution bandwidth: BW >
3. Set the frequency range: Freq/Dist >
4. Set the number of points: Sweep >
5. Use Meas Setup >
