Acquisition system

Acquisition modes

Sample

Acquire sampled values.

Peak Detect

Captures glitches as narrow as 1.5 ns (1 GHz models), 2.0 ns (500 MHz models), 3.0 ns (350 MHz models), 5.0 ns (200 MHz

models), 7.0 ns (100 MHz models) at all sweep speeds

Averaging

From 2 to 512 waveforms included in average.

Envelope

Min-max envelope reflecting Peak Detect data over multiple acquisitions. Number of waveforms in the envelope selectable

between 1 and 2000 and infinity

Hi Res

Real-time boxcar averaging reduces random noise and increases vertical resolution.

Roll

Scrolls waveforms right to left across the screen at sweep speeds slower than or equal to 40 ms/div.

FastAcq optimizes the instrument for analysis of dynamic signals and capture of infrequent events, capturing >280,000 wfms/s on

1 GHz models and >235,000 wfms/s on 100 MHz – 500 MHz models.

Waveform measurements

Cursors

Waveform and Screen

Automatic measurements

(time domain)

30, of which up to four 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.

Automatic measurements

(frequency domain)

3, of which one can be displayed on-screen at any one time. Measurements include Channel Power, Adjacent Channel Power

Ratio (ACPR), and Occupied Bandwidth (OBW)

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 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.

Spectrum math

Add or subtract frequency-domain traces.

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, TotalOverShoot, PeakPeak, Amplitude, RMS, CycleRMS, High, Low, Max, Min, Mean, CycleMean, Area,

CycleArea, and trend plots). For example, (Intg(Ch1 - Mean(Ch1)) × 1.414 × VAR1)
