Description<br />

DET Detection Mode<br />

XDET<br />

Initializes the spectrum analy.zer<br />

Activates single-sweep mode.<br />

Activates the positive-peak detection of trace A.<br />

Stores results in trace A.<br />

Activates sample detection for trace I3<br />

Measures with trace B<br />

Stores results in trace B<br />

Averages trace A <strong>and</strong> B with a ratio of 2, <strong>and</strong> stores<br />

the results in trace A.<br />

Blanks trace rj leaving on1 y averaged results on screen.<br />

The DET comm<strong>and</strong> selects the type of spectrum analyzer detection (positive-peak, sample, or<br />

negative) <strong>and</strong> accesses service-diagnostic detection functions.<br />

POS enables positive-peak detection, which displays the maximum video signal detected<br />

over a number of instantaneous samples for a particular frequency.<br />

SMP enables sample detection, which uses the instantaneous video signal value. Video<br />

averaging <strong>and</strong> noise-level markers, when activated, activate sample detection<br />

automatically.<br />

NEG enables negative peak detection in sweep times of less than or equal to 200 ms. The<br />

negative peak detector is available with Option 101 or Option 301 only.<br />
