HDO9000 High Definition Oscilloscopes Operator's Manual

List of Standard Operators

The math operators included standard with your oscilloscope are listed below alphabetically.

Note:

There may be additional operators available depending on the software options installed

on the oscilloscope.

Operator

Definition

Absolute

For every point in the waveform the distance away from zero is calculated. For values greater
than zero this is the same as the value. For values less than zero, the magnitude of this value
without regard to its sign is used.

Average

Calculates either a summed or continuous average of a selected number of sweeps. See

Aver-

aging Waveforms

. The maximum number of sweeps is determined by the oscilloscope model

and memory.

Copy

Copies waveform in its unprocessed state to the first available memory location.

Correlation

Calculates a measure of similarity of two waveforms, or a waveform against itself, as a function
of a time-lag applied to one of them.

Derivative

Calculates the derivative of adjacent samples using the formula:

(next sample value – current sample value) / (horizontal sample interval)

Deskew

Shifts trace in time the amount of the deskew factor.

Difference

For every point in the waveform, the value of Source2 is subtracted from the value of Source1.
Source1 and Source2 must have the same horizontal units and scale and the same vertical
units.

Envelope

Calculates highest and lowest vertical values of a waveform at each horizontal value for a spe-
cified number of sweeps.

ERes

Applies a noise reduction and smoothing filter by adding a specified number of bits. See

Enhanced Resolution

.

Exp

Calculates the antilog to the base e of the source; that is, e raised to the power equal to the
source.

Exp10

Same as Exp, using base 10.

FFT

Computes a frequency spectrum with optional Rectangular, Von Hann, Flat Topp, Hamming,
Blackman-Harris, and Hanning windows. Calculates up to 128 Mpts. Also allows FFT Aver-
aging through use of a second math operator. See

FFT

.

Floor

Calculates the lowest vertical values of a waveform at each horizontal value for a specified num-
ber of sweeps.

Histogram

Plots the number of data points that fall into statistically significant intervals or bins. Bar height
relates to the frequency at which data points fall into each interval/bin.

Integral

Calculates the linearly rescaled integral (with multiplier and adder) of a waveform input starting
from the left edge of the screen using the formula:

(current sample value + next sample value) * (horizontal sample interval)

Each calculated area is summed with the previous sum of areas. The multiplier and adder are
applied before the integration function.

Interpolate

Inserts points between sampled points (upsamples) according to one of three algorithms: Lin-
ear (straight line), Sinx/x (curved), and Cubic (spine). Interpolation factor of 2 to 50 determines
number of points in the upsample.

Invert

For every point in the waveform, the inverse of that point is calculated.
