Waveform measurements

Cursor types

Waveform, V Bars, H Bars, V&H Bars, and Polar (XY/XYZ plots only)

DC voltage measurement

accuracy, Average acquisition

mode

Measurement Type

DC Accuracy (In Volts)

Average of ≥ 16 waveforms

±((DC Gain Accuracy) * |reading - (offset - position)| + Offset

Accuracy + 0.1 * V/div setting)

Delta volts between any two averages of ≥ 16 waveforms

acquired with the same oscilloscope setup and ambient

conditions

±(DC Gain Accuracy * |reading| + 0.05 div)

Automatic measurements

36, of which an unlimited number can be displayed as either individual measurement badges or collectively in a measurement

results table

Amplitude measurements

Amplitude, Maximum, Minimum, Peak-to-Peak, Positive Overshoot, Negative Overshoot, Mean, RMS, AC RMS, Top, Base, and

Area

Timing measurements

Period, Frequency, Unit Interval, Data Rate, Positive Pulse Width, Negative Pulse Width, Skew, Delay, Rise Time, Fall Time,

Phase, Rising Slew Rate, Falling Slew Rate, Burst Width, Positive Duty Cycle, Negative Duty Cycle, Time Outside Level, Setup

Time, Hold Time, Duration N-Periods, High Time, and Low Time

Measurement statistics

Mean, Standard Deviation, Maximum, Minimum, and Population. Statistics are available on both the current acquisition and all

acquisitions

Reference levels

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

set to global for all measurements, per source channel or signal, or unique for each measurement

Gating

Screen, Cursors, Logic, Search, or Time. Specifies the region of an acquisition in which to take measurements. Gating can be set

to Global (affects all measurements set to Global) or Local (all measurements can have a unique Time gate setting; only one Local

gate is available for Screen, Cursors, Logic, and Search actions).

Measurement plots

Histogram, Time Trend, and Spectrum

Measurement limits

Pass/fail testing for user-definable limits on measurement values. Act on event for measurement value failures include Save

Screen Capture, Save Waveform, System Request (SRQ), and Stop Acquisitions
