Measurement setups Select a communications measurement
TIP. Turn on Fast Acquisitions to enhance your measurements. In Fast Acquisitions mode, measurements
are calculated on an array of acquired waveforms. As the waveforms accumulate (with persistence on),
your measurem
ent accuracy may increase. However, only one or two channels can be displayed when you
take automatic measurements using Fast Acquisitions mode.
If three or mo
re channels are displayed, Fast Acquisitions mode is turned off, and then the requested
measurements are made. Fast Acquisitions mode is not automatically turned back on when you select
fewer than three channels.
