General Safety Instructions
Please make sure to observe the instructions of the following sections so that you
cannot cause damage to the instrument or endanger people. This is of particular
importance when you use the instrument for the first time. Also observe the general
safety instructions at the beginning of this manual.
2.1 Front Panel Tour R&S OSP120
This chapter gives an overview of the front panel controls and connectors of the
R&S OSP120 and gives all information that is necessary to put the instrument into
operation and connect external devices. Notes on reinstallation of the instrument
software appear at the end of the chapter.
Chapter 3.3, R&S OSP Panel Functions, of this manual provides an introduction to the
operation of the instrument by means of the control program OSP Panel. For a
description of the operating concept and an overview of the instrument’s capabilities
refer to the Instrument Functions (chapter 5).
The front panel of the R&S OSP120 consists of STANDBY switch, Status LEDs and
connectors. Brief explanations on the function of these items and the rear panel can be
found on the next pages.

2.1.1 Status LEDs and Standby Key
The status LEDs and the standby toggle switch are located in the bottom right corner
of the front panel. See also chapter 2.5.9.
The status LEDs light to indicate the following instrument states:
PWR: shows standby (yellow LED) and ready state (green LED).
LAN: shows if data are received via LAN network.
CLK: is flashing if data are transferred via CAN bus.
On an R&S OSP150, the logic is inverted: the CLK indicator goes off shortly during
CAN bus activity.
The STANDBY key serves the following purpose:
Toggle between standby and ready state (indicated by the yellow and green PWR
