Limit, Bottom Limit, Left Limit, and Right Limit controls
to set the size of the histogram box. The histogram box
selects the section of the waveform used for histograms.

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 (CSA7000B Series only), see Optical Dark
Compensation on page 3--58 to perform a dark level calibration.
To compensate the instrument so that it can take accurate measurements based on
the ambient temperature, use the procedure that follows.

Prerequisites
1. Inst rum ent should be powered on. Allow a 20 minute
warm up. Remove all input signals.
