Attribute Summary:

Description:

The trace specifier, CALCulate[1|2|3|4], determines which trace you are selecting. Omit the specifier or

send 1 for trace A, 2 for trace B, 3 for trace C, or 4 for trace D.

A peak is a local maximum on the displayed trace. The slope of a trace is positive to the left of a peak

and negative to the right. In addition, the slope on one side of a peak must not change for at least one

vertical division (one-third division on both sides if in octave analysis instrument mode or one-tenth

division (one decade) if using logarithmic scaling of the Y-axis).

This command only finds peaks that are at least one point to the left of the current marker position. If the

analyzer does not find a peak, the marker does not move. You can increase the number of peaks found by

the analyzer by decreasing the value of vertical scale division (DISP:TRAC:Y:PDIV).
