Fields

Detector

This field is used to select the type of detector used to measure the amplitude of the audio signal being analyzed by the Audio Frequency Analyzer.

See “AF Analyzer” in the GPIB Command Syntax chapter of the E8285A Condensed Programming Reference Guide for programming command syntax.

Detector Types

RMS displays the RMS value of signals.

RMS*SQRT2 displays the RMS value of a signal multiplied by 2 . Pk+ displays the positive peak value.

Pk− displays the negative peak value.

Pk±/2 adds the positive and negative peak values, and divides the sum by 2. Pk±Max compares the positive and negative peaks and displays the greater value (polarity is not indicated).

Pk+ Hold displays and holds the positive peak value until the measurement is reset. To reset, press the Meas reset key, select a different detector, or re-select the same de- tector.

Pk− Hold displays and holds the negative peak value until the measurement is reset. To reset, press the Meas reset key, select a different detector, or re-select the same de- tector.

Pk±/2 Hold divides the sum of the positive and negative peak values by 2, and dis- plays the value until the measurement is reset. To reset, press the Meas reset key, select a different detector, or re-select the same detector.

Pk±Mx Hold compares the positive and negative peaks and displays the greater value until the measurement is reset. To reset, press the Meas reset key, select a different de- tector, or re-select the same detector.
