Enabling Precision Measurements and Math

242
Normally, after pressing [Save/Recall] > Default Setup, the oscilloscope performs
measurements and generates math waveforms using a 1000-point (maximum)
measurement record. This measurement record is purposely small in order to provide
high waveform update rates and minimal "dead time" between acquisitions to improve
the probability of capturing infrequent events.
However, at the expense of waveform update rate, you can enable precision
measurements and math waveforms that use a 128K-point (maximum) record. This mode
gives you better resolution on measurements and math waveforms (including FFT).
To enable precision measurements and math:
1 Press [Utility] > Options.
2 In the User Options Menu, select Precision to enable precision measurements and
math waveforms.
Precision measurements and math are disabled in the same way, or you can disable them
by pressing [Save/Recall] > Default Setup.
