Repeat Sweep
Continuously sweeps until the measurement is canceled or the instrument
is set to Single Sweep.
Fast access to the Trigger Mode setting is from the icon on the toolbar.
Tip:
Measure Menu
Starts the measurement process as specified in the Setup menu. A
measurement progress indicator is shown at the bottom left of the display.
The indicator only appears during a measurement.
Accesses the Normalization setup panel. Normalization is used to
measure the loss and group delay of the test path. Later this data is
subtracted from the DUT measurement to generate measurement results.
Refer to "Normalization Range" on page 100
normalization settings.
A normalization can optionally run the following tests:
• Length
If a Length measurement is specified with the Measure mode, the
Normalization path's length is measured so that it can be subtracted out.
DUT Length = Total Length - Normalized Path Length.
Refer to "Length" on page 98
• Wavelength Correction
Using the optional 86122A multi-wavelength meter, wavelength correction
is performed for stepped normalizations. That is, when Setup > CD/PMD >
is set to one of the two stepped measurement modes. Wavelength
correction is always performed if an 86122A is connected. Five wavelength
points are measured and the average offset is applied.
