DET Detection Modes
If no detector mode is specified, the following rules determine the
chosen detector.
1. If video averaging or marker noise functions are on, or if the
resolution bandwidth is greater than or equal to 300 Hz and the
video bandwidth is less than 300 Hz, the detector is set to sample
mode.
2. If the sweeptime is less than 30 ms, the detector is set to sample
mode. Positive and negative peak detection are available with
sweeptimes less than 30 ms if Option 007 is installed. (Sweeptimes
of less than 50 ms are available only if the spectrum analyzer
frequency span is set to zero.)
3. If the maximum-hold trace mode is on, the positive peak detector is
used.
4. If the minimum-hold trace mode is on, the negative peak detector is
used.
5. If none of the above rules apply, the normal detector is used.
6. If more than one of the above rules applies, the first rule listed
determines the detector used.
