Measurements and math
Waveform measurements
Voltage Peak to peak, minimum, maximum, average, RMS, amplitude, base, top, overshoot, preshoot,
upper, middle, lower.
Time Rise time, fall time, period, frequency, positive width, negative width, duty cycle, burst width,
Tmin, Tmax, setup time (requires Option 002 or 004), hold time (requires Option 002 or 004),
delta time, channel-to-channel phase.
Mixed Area, slew rate.
Frequency domain FFT frequency, FFT magnitude, FFT delta frequency, FFT delta magnitude.
Level qualification Any channels that are not involved in a measurement can be used to level qualify all timing
measurements.
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 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 absolute value, add, average, common mode, differentiate, divide,
FFT magnitude, FFT phase, high pass filter, integrate, invert, low pass filter (4th order Bessel
Thompson Filter), magnify, max, min, multiply, smoothing, square, square root, subtract, versus,
and optional user defined function (Option 010).
