HDO4000 High Definition Oscilloscope

Function

Definition

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
number of sweeps.

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.

Invert

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

Product

For every point in the waveform, the value of Source1 is multiplied by the value of Source 2.
Source1 and Source2 must have the same horizontal units and scale.

Ratio

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

Reciprocal

For every point in the waveform the inverse is calculated using the formula:

1 / (sample value)

Rescale

For every point in the waveform the sample value is multiplied by the specified multiplier and
then add to with the specified adder. See

Rescaling and Assigning Units

.

Roof

Calculates the highest vertical values of a waveform at each horizontal value for a specified
number of sweeps.

Square

For every point in the waveform, the square of the sample value is calculated.

Square Root

For every point in the waveform, the square root of the sample value is calculated.

Sum

For every point in the waveform, the value of Source1 is added to the value of Source 2.Source1
and Source2 must have the same horizontal units and scale and the same vertical units.

Trend

Produces a waveform composed of a series of parameter measurements in the order the
measurements were taken. The vertical units are those of the source parameter, the horizontal
unit is measurement number. The trend contains a single value for each measurement. See

View Trend

.

Zoom

Produces a magnified trace of a selected portion of the input waveform. See

Zooming Traces
