Description
Returns trace A data.
Returns trace B data.
Controls trace data input and output.
Returns a nonnegative integer that
indicates the total number of trace

TRDSP
registers available for SAVET and RCLT.
Creates a user-defined trace.
Turns on or off the display of trace A, B,
or C without clearing the trace

(measurements can still be taken).
Displays a compressed trace on the
analyzer display.
Sets the trace operations to their preset
values.
Returns the status of traces A, B, and C:
clear write, blank, view, minimum hold,
or maximum hold.
Creates a window trace array for the
fast Fourier transform (FFT) function.
VID AVG ON OFF
Enables the video-averaging function,
which averages trace points to smooth
the displayed trace.

AVG ON OFF
Adds trace A to trace B and sends the
result to trace A.
Restarts video averaging.
Reduces the number of trace elements
while retaining the relative frequency
and amplitude characteristics of the
trace data.
Combines two traces.
Calculates fast Fourier transform.
Fills linear interpolated data into the
specified trace data points of a
destination trace.
Displays the mirror image of a trace.
Sorts signal peaks by frequency or
amplitude, stores the results
ln
the
destination trace, and returns the
number of peaks found.
Smooths the trace according to the
number of points specified for the
running average.
Returns the sum of the amplitudes of
the trace elements in measurement
lullts.
Returns the sum of the squares of the
amplitude of each trace element.
Executes a
list
of analyzer commands at
the end of each sweep.
Exchanges traces.
