R&S OSP
2.4.2 CAN Bus Connector
9-pin connector D-Sub male used to connect the R&S OSP120 or R&S OSP130 to
extension units R&S OSP150. Refer to Instrument Functions in
Maximum input levels
The maximum input levels and voltages of the input connectors at the front and rear
panel must not be exceeded.
Supply Voltage over CAN bus
In some CAN bus applications the R&S OSP120, OSP130 or OSP150 is required to
deliver the supply voltage to an external device. An example for this is the connection
of the fiber-optic extender R&S OSP-Z104. Using the cable OSP-Z106 is
recommended for this case.
However, when connecting an R&S OSP150 to an OSP120 or OSP130, this supply
voltage line must not be present. Using the connecting cables R&S OSP-Z101 or
R&S OSP-Z102 is recommended. Not observing these precautions may damage the
power supplies in the R&S OSP.
