Part 6: IEEE 488.2 Command Reference
Parameters Values Description
LENGTH <length> Number of points to use from first waveform in Correlate function.
MAXEVENTS <#events>
Number of events computed in Histogram function. See product datasheet for
maximum value.
MAXBINS <#bins> Number of bins used to compute Histogram.
START <start> Starting point in second waveform for Correlate function.
SWEEPS <#sweeps> Number of sweeps used to compute function. See the product datasheet for
maximum value.
UNITS <unit> Physical unit in which to express function result. See
table of unit mnemonics
.
VERT <vert_scale> Vertical scaling type.
WEIGHT <weight> Continuous Average function weighting factor.
WIDTH <width> Width of histogram display.
WINDOW <window_type> FFT window function. See FFT operator for list of window types.
Equation Notation
The equation value is a string comprised of the math operator followed immediately by the source(s) in
parentheses. Enclose the entire equation string in quotes. Follow the equation pair with any additional
parameter pairs relevant to the operation. For example:
F1:DEFINE EQN,'AVG(C1)',AVERAGETYPE,SUMMED
Include text in caps and special characters (e.g., parentheses) as shown in the tables below. Substitute
variable text shown here in angle brackets with acceptable values. Use one of the values listed in curly
brackets.
All MAUI Oscilloscopes
These operators are standard on all MAUI oscilloscopes running XStreamDSO v. 8.0.0 or higher.
Operators Additional Parameters Description
ABS( <source>) Absolute Value
AVG (<source>) AVERAGETYPE,{SUMMED,CONTINUOUS}
WEIGHT,<value>
Average of single waveform.
Specify WEIGHT for Continuous
Averaging.
DERI(<source>) VERSCALE,<verscale>
VEROFFSET,<veroffset>
ENABLEAUTOSCALE,{ON, OFF}
Derivative of waveform using subtraction
of adjacent samples.
<source1>–<source2> Difference between two waveforms.
