SD-44 Instruction Manual

Getting Started

The SD-44 is an optical-to-electrical (O/E) converter that converts an optical
input signal into an output voltage for display on either a high-speed oscillo-
scope or spectrum analyzer. The converter accepts optical signals from DC up to
15 GHz. The SD-44 O/E converter installs in any of the front panel compart-
ments of a Tektronix 11800 Series Digital Sampling Oscilloscope, the SM-11
Multichannel Unit, or the Tektronix CSA 803 Communications Signal Analyzer.
An optional stand-alone power supply is also available for the SD-44 O/E
converter (see page 20).

Figure 1 shows the front panel of the SD-44 O/E converter.

The SD-44 O/E converter has an FC/PC receptacle for optical signal input and a
precision 3.5 mm connector for electrical signal output.

The following list highlights the key performance characteristics of the SD-44
O/E converter:

H

1000 to 1650 nm wavelength response

H

15 GHz Minimum Transducer Bandwidth

H

35 mV/mW of DC conversion gain at 1310 and 1550 nm

For a complete list of specifications, see to page 10.
