4-12. Test Equipment Required. The following test equipment is required to test the laser output power. Laser
Power Meter, United Detector Technology (Model No. 351 L)
4-13. Procedure
a. Connect the Hp 5517B to either the Hp 5501A or HP 5527A system (or any suitable dual DC voltage power
supply such as the HP 6255A) using HP 10791A/B/C or HP 10793A/B/C cable.
