HDO6000 High Definition Oscilloscope
Function Definition
DigitalAND AND function between two digital waveforms (-MS models only).
DigitalFlipFlop Input1 is clocked in a hold when a rising edge of input2 occurs (-MS models only).
DigitalNAND NAND function between two digital waveforms (-MS models only).
DigitalNOR NOR function between two digital waveforms (-MS models only).
DigitalNOT NOT function (inverter) of a digital waveform (-MS models only).
DigitalOR OR function between two digital waveforms (-MS models only).
DigitalXOR XOR function between two digital waveforms (-MS models only).
Envelope Calculates highest and lowest vertical values of a waveform at each horizontal value for a
specified 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 1 Mpts. Also allows FFT Averaging
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.
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: Linear
(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.
Ln Peforms a natural log of a waveform. Values less than or equal to zero are set to underflow.
Log10 Performs a log base 10 of a waveform. Values less than or equal to zero are set to underflow.
MatLab math Applies a pre-programmed MatLab math function to the source waveform. Requires XDEV
option to edit functions through the oscilloscope GUI using MatLab Script.
phistogram Creates a histogram based on the displayed pixels of a waveform falling within a user defined
vertical or horizontal box (slice).
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.
ptrace mean Plots the mean value of each sample point in a persistence map.
ptrace range Generates a waveform with a width derived from the population range of a persistence map.
ptrace sigma Generates a waveform with a width derived from the sigma (sum) of a persistence map.
