Measure Commands
Measure Commands
The commands in the MEASure subsystem are used to make parametric measurements on
displayed waveforms. The 86100C has four modes: Eye/Mask, Jitter, TDR/TDT, and Oscillo-
scope. Each mode has a set of measurements. In Eye/Mask mode, all of the measurements
are made on the color grade/gray scale data, with the exception of average optical power and
histogram measurements.
Measurement
Setup
To make a measurement, the portion of the waveform required for that measurement must be
displayed on the analyzer.
• For a period or frequency measurement, at least one and one half complete cycles must be dis-
played.
• For a pulse width measurement, the entire pulse must be displayed.
• For a rise time measurement, the leading (positive-going) edge of the waveform must be dis-
played.
• For a fall time measurement, the trailing (negative-going) edge of the waveform must be dis-
played.
• A valid source for the measurement must be designated. This can be done globally with the
MEASure:SOURce command or locally with the optional source parameter in each measure-
ment.
User-Defined
Measurements
When user-defined measurements are made, the defined parameters must be set before actu-
ally sending the measurement command or query.
Measurement
Error
If a measurement cannot be made because of the lack of data, because the source signal is
not displayed, the requested measurement is not possible (for example, a period measure-
ment on an FFT waveform), or for some other reason, 9.37 is returned as the mea-
surement result. In TDR mode with ohms specified, the returned value is 838M
Ω.
If
SENDvalid is ON, the error code is also returned.
