Calibration; Register-Level Programming Information - National Instruments NI 6608 User Manual

Chapter 2 Device Overview

Calibration

Note When calibrating the NI 6608, use an external clock with a short-term stability (over
a period of 100 s) of better than 5 × 10
calibrated. A typical rubidium time standard will meet the required stability.

Register-Level Programming Information

Caution NI is not liable for any damage or injury that results from register-level
programming the TIO Series devices.
