Step Action Notes
1. Turn the instrument on — Press the power key To obtain optimum measurement accuracy, it is
recommended the analyzer warm up for 30
minutes.
2. Select the mode and

If you are using other noise sources, for example,
the Keysight 346B noise source, you need to enter
the ENR values manually.
For more information about entering the ENR
data, refer to “Entering Excess Noise Ratio
(ENR) Data” on page 64 .
Note that for calibration and for making
measurements, the ENR data for different
frequency ranges are used.
