Waveform measurements

Cursors Waveform and Screen.

Automatic measurements

(time domain)

30, of which up to eight can be displayed on-screen at any one time. Measurements include: Period, Frequency, Delay, Rise Time,

Fall Time, Positive Duty Cycle, Negative Duty Cycle, Positive Pulse Width, Negative Pulse Width, Burst Width, Phase, Positive

Overshoot, Negative Overshoot, Total Overshoot, Peak to Peak, Amplitude, High, Low, Max, Min, Mean, Cycle Mean, RMS, Cycle

RMS, Positive Pulse Count, Negative Pulse Count, Rising Edge Count, Falling Edge Count, Area and Cycle Area.

Measurement statistics Mean, Min, Max, Standard Deviation.

Reference levels User-definable reference levels for automatic measurements can be specified in either percent or units.

Gating Isolate the specific occurrence within an acquisition to take measurements on, using either the screen, or waveform cursors.

Waveform histogram A waveform histogram provides an array of data values representing the total number of hits inside of a user-defined region of the

display. A waveform histogram is both a visual graph of the hit distribution as well as a numeric array of values that can be

measured.

Waveform math

Arithmetic Add, subtract, multiply, and divide waveforms.

Math functions Integrate, Differentiate, FFT.

FFT Spectral magnitude. Set FFT Vertical Scale to Linear RMS or dBV RMS, and FFT Window to Rectangular, Hamming, Hanning, or

Blackman-Harris.

Advanced math Define extensive algebraic expressions including waveforms, reference waveforms, math functions (FFT, Intg, Diff, Log, Exp, Sqrt,

Abs, Sine, Cosine, Tangent, Rad, Deg), scalars, up to two user-adjustable variables and results of parametric measurements

(Period, Freq, Delay, Rise, Fall, PosWidth, NegWidth, BurstWidth, Phase, PosDutyCycle, NegDutyCycle, PosOverShoot,

NegOverShoot, PeakPeak, Amplitude, RMS, CycleRMS, High, Low, Max, Min, Mean, CycleMean, Area, CycleArea, and trend

plots), e.g.,(Intg(Ch1 - Mean(Ch1)) × 1.414 × VAR1).

Act on Event

Events None, when a trigger occurs, or when a defined number of acquisitions complete (1 to 1,000,000)

Actions Stop acquisition, save waveform to file, save screen image, print, AUX OUT Pulse, remote interface SRQ, e-mail notification, and

visual notification.

Repeat Repeat the act on event process (1 to 1,000,000 and infinity)
