ORR24 Instruction Manual

1

Getting Started

The ORR24 is an optical reference receiver that is precisely calibrated in the
frequency domain for the SONET/SDH data rate of 2.488 Gb/s
(STM-16/OC-48). The ORR24 reference receiver installs in the front panel
compartment of a Tektronix 11800 Series Digital Sampling Oscilloscope
(including the SM-11 Multichannel Unit) or Tektronix CSA 803 Communica-
tions Signal Analyzer. Along with the appropriate sampling head, the ORR24
reference receiver and the CSA 803 or 11800 series instruments can test the
compliance of optical signals to specific SONET/SDH standards. An optional
stand-alone power supply is also available for the ORR24 Optical Reference
Receiver (see page 21).
