Measurement Modes

Automatic Measurements

Measure menu access to all measurements, 4 measurements can be displayed simultaneously

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

the displayed waveforms

Statistics

Displays the mean, standard deviation, minimum and maximum measurement values for the

displayed automatic measurements

Histograms (analog 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,

peak-to-peak value, median, total hits, peak (area of most hits), and mean ± 1,2, and 3 sigma

Eye Diagram Measurements

Eye diagram display mode allows triggering on both negative-going and positive-going

edges of a signal. Eye diagram measurements include eye height, eye width, jitter, crossing

percentage, Q factor, and duty cycle distortion

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

4 functions f1-f4. Select from Add, Average, Differentiate, Divide, FFT Magnitude, FFT Phase,

High Pass Filter, Integrate, Invert, Low Pass Filter, Magnify, Min, Max, Multiply, Subtract, Versus

FFT

DC to 2 GHz (2 channels interleaved), DC to 1 GHz (each channel)

Frequency Resolution

Resolution = Sample Rate / Memory Depth
