Noise Figure Mode (Option 356)
How to Define a Noise Figure Measurement
IMPORTANT! Save your noise source table with a unique filename to avoid
loss of table data. All noise figure files are saved with *.enr type suffixes.
The FieldFox displays Replace existing file?, because the displayed
default filename is the one last saved. Enter a unique filename to avoid
loss of table data (i.e., all noise figure files are saved with *.enr type
suffixes).
