Analog Measurements - Screens and Control Fields

Control Fields for Analog Measurements

Sensitivity (spectrum analyzer)

This area performs two functions:

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

The upper field selects Normal or High sensitivity for the RF input. The High setting adds about 6 dB of sensitivity to the ANT IN port (when the Input Atten field is set to 0 dB) 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.

Settling

This field selects the settling time for making AF measurements. Lower frequency signals require additional settling time (Slow). Higher frequency measurements require less settling time (Fast).

Operating Considerations

Use Slow for ≤ 200 Hz signals. Use Fast for >200 Hz signals.

If the signal being measured is a composite of different frequencies above and below 200 Hz, select the appropriate filtering to analyze the desired signal component.
