The Tektronix SD42, SD43, SD44 and SD48 are optical-to-electrical (O/E) converters for use with the Tektronix CSA803 and 11800 Series sampling oscilloscopes equipped with an SD2x or SD3x Electrical Sampling Head. The SD42, SD43, SD44 and SD48 Optical-to-Electrical Converters can be plugged directly into an 11800 sampling slot or CSA803 power slot.
Optical signal input on the Tektronix SD42, SD43, SD44 and SD48 is a standard FC/PC fiber optic connector. Other connector types can be accommodated by using optional hybrid fiber optic jumper cables (SD42) or an assortment of hybrid mating adapters which are standard with the SD43, SD44 and 48. The SD42 has an average power meter capability when used with a Digital Multimeter (DMM) which has selectable ranges of 1 V/mW and 1 V/ MicroW.
