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.
Detector Types
•
RMS displays the RMS value of signals.
•
RMS*SQRT2 displays the RMS value of a signal multiplied by
•
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
detector.
•
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
detector.
•
Pk±/2 Hold divides the sum of the positive and negative peak values by 2, and
displays 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
detector, or re-select the same detector.
