Recommended calibration adjustment equipment
The table below contains the recommended equipment for the calibration adjustment procedures.
You can use alternate equipment as long as that equipment has specifications equal to or greater
than those listed in the table. When possible, test equipment specifications should be at least four
times better than corresponding Series 2600B specifications.
