Mask Testing

Allows pass/fail testing to user-defined or Agilent-supplied waveform templates. Up to 8 regions of polygons
allowed. Mask inversion inverts mask around baseline. Test modes include test forever, test to specified time or
event limit, and stop on failure. Auto-mask allows user to define tolerance range in time/voltage or percentage
and create a mask template from a captured waveform. Masks can be automatically aligned with the incoming
signal. All masks can be manually scaled via controls or the mouse.

Communications Mask Option

Option 100 provides a set of ITU G.703 and ANSI T1.102 industry standard masks for compliance testing.
For a complete list of the masks provided, request Agilent Communications Mask Testing Option 100
technical data sheet (see page 8)

Measurement Toolbar

16 Drag and Drop automatic measurement icons.

QuickMeas+

Allows user to configure a button below the display for the following functions:
QuickMeas: activates 4 preselected automatic measurements. QuickPrint: prints out screen.

QuickScreen: saves screen image to file; multiple button pushes increments filename suffix (e.g. Data01, Data02, etc.).

QuickWaveform: saves waveform data to a file on the disk drive; multiple button pushes increments filename suffix.
QuickSetup: loads in a specific instrument setup file

Markers Modes

Manual Markers, Track Waveform Data, Track Measurements

Waveform Math

4 functions f1-f4. Select from Add, Subtract, Multiply, Divide, Invert, Magnify, Vs, Min, Max, Integrate,
Differentiate, FFT Magnitude. Any of the Waveform Math functions (e.g., FFT) can be averaged.
