Agilent Technologies E8285A manual Sensitivity, Serial Baud, This area performs two functions

Chapter 4, Description of Fields

Fields

Sensitivity

RF Analyzer sensitivity adds about 6 dB of sensitivity for the ANTENNA IN port when High is selected.

Operating Considerations

Selecting High sensitivity may cause Spectrum Analyzer measurements to be uncalibrated when the ANTENNA IN port is used (a message appears when this occurs).

High-level AM measurements may be distorted when high sensitivity is used with the ANTENNA IN port.

RF ANALYZER

Sensitivity

This area performs two functions:

•The upper field selects Normal or High sensitivity for the RF input. The High setting adds about 6 dB of sensitivity to the ANTENNA IN port for looking at very low level signals. However, this setting can cause measurements to be uncalibrated (indicated by a message on the screen). High sensitivity can also cause high-level AM signals to be distorted.

•The lower field selects the vertical resolution of the display. You can choose from 1 dB, 2 dB, or 10 dB per graticule.

Serial Baud

This field selects the baud rate for serial communications when using the rear- panel serial port. Selecting this field displays a list of baud rate choices.

This setting is maintained after the instrument is turned off.
