Optimizing Measurement Accuracy
The procedures given here will increase the accuracy of the measurements that
you take.
This instrument can compensate itself and the attached probes, optimizing the
internal signal path used to acquire the waveforms you measure. Compensation
optimizes the capability of the instrument to take accurate measurements based
on the ambient temperature.
If you are using optical signals (CSA7000 Series only), see Optical Dark
Compensation on page 3--67 to perform a dark level calibration.
