Required Test Equipment List
The following table identifies the equipment recommended for
troubleshooting, adjusting, and verifying the performance of the instrument.
Only the recommended and alternate equipment is compatible with the
performance verification testing. Some tests can use various models of a
particular equipment type. The “Recommended Keysight Model” is the
preferred equipment. However, the “Alternative Keysight Model” is an
acceptable substitute.
