- Page 12 CSA 803 Communications Signal Analyzer. The SD-42/SD-46 Optical-to- Electrical Converter Heads are used with SD-22, SD-24, and SD-26 Sampling Heads. The SD-42/SD-46 converts an optical signal into an electrical signal which serves as the input to an SD Series Sampling Head.
- Page 13 For best repeatability and to prolong the life of connectors, use a torque wrench and tighten the connection to the range of 7–10 lb-in (79–112 N-cm). The front of the SD-42/SD-46 has a precision FC/PC optical connector receptacle. This is for attaching a fiber optic signal cable. This connector receptacle has a locating keyway.

For the converted output signal from the SD-42/SD-46 to be sampled, the output of the SD-42/SD-46 must be connected to the input of an SD-24 or SD-26 Sampling Head (the SD-42 can also be connected to an SD-22). To accomplish this using the U-link provided with the SD-42/SD-46, the SD-24 or SD-26 must be in the plug-in slot immediately to the right of the slot occupied by the SD-46. - Page 15 Getting Started 1–4 SD-42 & SD-46 User Manual...

A fiber terminated by an FC/PC style connector is connected to the FC/PC style input on the front of the SD-42/46. Care must be taken to ensure alignment of the key on the FC/PC connector with the keyway of the connector receptacle. - Page 19 The two 2 mm MONITOR sockets on the front of the SD-42/46 can be connected to most common digital voltmeters using the two 2 mm to 4 mm cables supplied with the SD-42/46.

Performance Check Optical Power Monitor Check The Optical Power Monitor function of the SD-42/SD-46 does not use any of the oscilloscope functions. However the oscilloscope must be switched on and the electrical output of the SD-42/SD-46 must be terminated, preferably using the high-performance U-link connected to an adjacent SD-24/26. -
