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
