Field Descriptions
Detector
This setting selects the type of detector used when measuring and displaying AF
signal levels.
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, or select a different detector, or reselect 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 reselect 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 reselect 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 reselect the same detector.
