Explanation
Limitations
Automated measurement of waveform parameters cannot be performed on the following
waveforms.
• Snapshot waveforms
• Accumulated waveforms other than the newest waveform.
• Sub waveforms measured using the dual capture function (version 3.10 or earlier.
However, if you load the measured data of Version 3.10 or earlier into a DL750/DL750P
of Version 4.01 or later, automated measurement of waveform parameters is possible.)
Measurement Parameters: Item Setup
You can select among the 28 types of measurement parameters shown below and delay
between channels. Up to 48000 combinations of parameters of all traces (CH1 to CH16
and Math1 to Math8) can be saved.

selected, the screen shows "Rms = overall value." For details on the power spectrum computation, see
sections 10.3 and 10.5. For details on the overall value, see page App-19.
