Measurements and math DSO8064A, MSO8064A, DSO8104A, MSO8104A
Waveform measurements
Voltage (scope channels only) Peak-to-peak, minimum, maximum, average, RMS, amplitude, base, top, overshoot,
preshoot, upper, middle, lower, runt (with InfiniiScan)
Time (all channels) Period, frequency, positive width, negative width, duty cycle, delta time
Time (scope channels only) Rise time, fall time, Tmin, Tmax, channel-to-channel phase, setup time, hold time
Mixed (scope channels only) Area, slew rate
Frequency domain FFT frequency, FFT magnitude, FFT delta frequency, FFT delta magnitude
Eye pattern Eye height, eye width, jitter, crossing %, Q-factor, duty cycle distortion
Jitter clock (scope only) Cycle-cycle jitter, N-cycle jitter, cycle-cycle +width, cycle-cycle –width, cycle-cycle duty
cycle (all with EZJIT)
Jitter data (scope only) Time interval error (TIE), data rate, unit interval (all with EZJIT)
Measurement modes
Automatic measurements Measure menu access to all measurements, five measurements can be displayed
simultaneously with statistics
QuickMeas+ Front-panel button activates five pre-selected or five user-defined automatic
measurements
Drag and drop measurement toolbar Measurement toolbar with common measurement icons that can be dragged and dropped
onto a particular displayed waveform cycle
Statistics
Displays the mean, standard deviation, minimum, maximum range, and number of measurement values for the displayed automatic
measurements.
Histograms (scope channels only)
Vertical (for timing and jitter measurements) or horizontal (noise and amplitude change) modes, regions are defined using waveform
markers. Measurements included: mean, standard deviation, mode, peak-to-peak, median, total hits, peak (area of most hits), and
mean ± 1, 2, and 3 sigma.
Mask testing
Allows pass/fail testing to user-defined or Agilent-supplied waveform templates.
AutoMask
Allows user to create a mask template from a captured waveform and define 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.
Marker modes
Manual markers, track waveform data, track measurements
Waveform math
Four functions f1-f4. Select from add, average, common mode, differentiate, divide, FFT magnitude, FFT phase, high pass filter,
integrate, invert, low-pass filter, magnify, min, max, multiply, smoothing, subtract, versus
FFT
Frequency range 8DC to 2 GHz (2 channels), DC to 1 GHz (each channel)
Frequency resolution Resolution = sample rate/memory depth
Best resolution at maximum sample rate 4 GSa/s/32 M = 125 Hz
Frequency accuracy (1/2 frequency resolution) + (5x10-5) (signal frequency)
Signal-to-noise ratio 980 dB at 1 Mpts memory depth
Window modes
Hanning, flattop, rectangular
8. FFT amplitude readings are affected by input amplifier roll-off; DSO8064A and MSO8064A: –3 dB at 600 MHz, with amplitude
decreasing as frequency increases above 600 MHz; DSO8104A and MSO8104A: –3 dB at 1 GHz, with amplitude decreasing as
frequency increases above 1 GHz.
9. Noise floor varies with memory depth and with averaging on or off.
