Logic: Trigger when any logical pattern of channels goes false or stays true for specified period of time. Any input can be used as
a clock to look for the pattern on a clock edge
Setup&Hold: Trigger on violations of both setup time and hold time between clock and data present on any channel
Rise/Fall Time: Trigger on pulse edge rates that are faster or slower than the specified
Video: trigger on all lines, odd, even, or all fields on NTSC, PAL, and SECAM video signals
HD video (option S03): Trigger on 480p/60, 576p/50, 720p/50, 720p/60, 1080i/50, 1080i/60, 1080p/24, 1080p/25, 1080p/30,
1080p/50 and 1080p/60
Measurement
and analysis
system
Auto measurement
30, of which up to eight can be displayed on-screen at any one time Measurements include: period, frequency, delay, top drop,
rise time, fall time, positive duty cycle, negative duty cycle, positive pulse width, negative pulse width, burst width, phase,
positive overshoot, negative 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
Cursor Waveform and screen
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
Source: CH1~CH4, REF1~REF4, math
Type: vertical, horizontal
Measurement types: 12, including waveform count, hits in box, peak hits, median, max, min, peak-to-peak, mean, standard
deviation, Sigma 1, Sigma 2 and Sigma 3
Waveform mathematics
Arithmetic: addition, subtraction, multiplication and division
Math functions: integrate, differentiate, FFT
FFT: Set FFT vertical scale to Linear RMS or dBVRMS, and set FFT window to Rectangular, Hamming, Hanning or
Blackman-Harris
Advanced math: Define extensive algebraic expressions including waveforms, reference waveforms, math functions, scalars, up
to two user-adjustable variables and results of parametric measurements
