Calibrating and Adjusting
This chapter normally gives you instructions for calibrating and adjusting the logic analysis system. Because the HP 16500B/16501A requires no calibration, only adjustment instructions are included.
Adjustments
The only adjustments to the logic analysis system are adjustments to the color CRT monitor assembly.
Use the following procedures to adjust the CRT module to compensate for magnetic influences causing misconvergence.
Hazard voltages exist on the power supply, the CRT, and the CRT driver board. To avoid electrical shock, read and follow the Safety and Warning considerations at the end of this manual before performing adjustment procedures.
Adjustment Interval
DO NOT PERFORM THESE ADJUSTMENTS AS A PART OF ROUTINE CALIBRATIONS. The following procedures are provided only for the few extreme cases where either the earth’s magnetic field or the user’s environment cause an unusable display due to misconvergence that cannot be corrected by degaussing the entire CRT screen.
DO NOT perform the procedures in this chapter before first degaussing the CRT screen using the
Adjustment Personnel
It is recommended that these adjustments be performed only by qualified personnel who are familiar with color CRT convergence procedures.
Equipment Required
The instrument firmware supplies the display patterns necessary for adjustment. The only tool required is a nonmetallic adjustment tool:
•Sony Part Number
•HP Part Number
