Measurements and math
Waveform measurements
Voltage Peak to peak, minimum, maximum, average, RMS, amplitude, base, top, overshoot, preshoot,
upper, middle, lower, area.
Time Period, frequency, positive width, negative width, duty cycle, delta time, rise time, fall time,
Tmin, Tmax, channel-to-channel phase.
Frequency domain FFT frequency, FFT magnitude, FFT delta frequency, FFT delta magnitude, FFT phase.
Statistics Displays the mean, standard deviation, minimum, maximum and number of measurements
value for the displayed automatic measurements.
Histograms Vertical (for timing and jitter measurements) or horizontal (noise and amplitude change) modes,
regions are defined using waveform markers. Measurements included: mean, standard
deviation, peak-to-peak value, median, min, max, total hits, peak (area of most hits), and
mean ± 1, 2, and 3 sigma.
Eye-diagram measurements Eye-diagram measurements include eye height, eye width, eye jitter, crossing percentage,
Q factor, and duty-cycle distortion.
Jitter analysis measurements Cycle-cycle jitter, N-cycle jitter, cycle-cycle + width, cycle-cycle – width, cycle-cycle duty cycle,
(E2681A EZJIT or N5400A EZJIT Plus data rate, unit interval, time interval error data, time interval error clock, setup time, hold time,
jitter analysis software) phase, period, frequency, + width, – width, duty cycle, rise time, fall time.
Mask testing Allows pass/fail testing to user-defined or Agilent-supplied waveform templates. AutoMask
lets you create a mask template from a captured waveform and define a tolerance range in
time/voltage or percentage. Test modes include test forever, test to specified time or event
limit, and stop on failure. Communications Mask Test Kit option provides a set of ITU-T G.703,
ANSI T1.102, and IEEE 802.3 industry-standard masks for compliance testing.
Waveform math Four functions, select from add, average, differentiate, divide, FFT magnitude, FFT phase,
integrate, invert, magnify, min, max, multiply, subtract, versus, common mode, smoothing, high
pass filter, low pass filter.
