Agilent Technologies E5500 Phase Noise Measurement System 16-13
Advanced Software Features
Blanking Frequency and Amplitude Information on the Phase Noise
Blanking Frequency and Amplitude Information
on the Phase Noise Graph
CAUTION Implementing either of the ‘‘secured’’ levels described in this section is not
reversible. Once the frequency or frequency/amplitude data has been
blanked, it can not be recovered. If you need a permanent copy of the data,
you can print out the graph and parameter summary before you secure the
data and store the printed data to a secured location.
NOTE An alternate method of storing classified data is to save the measurement
test file (*.pnm), including the real frequency/amplitude data onto a floppy
diskette and securing the diskette. It can then be recalled at a later data.
