2.5.9 Standby and Ready State
The STANDBY toggle switch is located in the bottom right corner of the front panel.
After switching on the AC power, the R&S OSP is in ready mode after about
30 seconds.
Press the STANDBY key on the front panel briefly to switch the R&S OSP from the
standby to ready state or vice versa.
In standby state, the left PWR LED is yellow. The standby power only supplies the
power switch circuits. In this state it is safe to switch off the AC power and disconnect
the instrument from the power supply.
After Power On or when changing from Standby to Ready state, the left PWR LED is
immediately switched to green and all modules are power-supplied. Please note that
the Linux operating system of R&S OSP takes about 30 seconds to start up. After this
time the R&S OSP is ready for operation.
Shock hazard
The instrument is still power-supplied while it is in standby mode.
2.6 Maintenance
The R&S OSP does not require any special maintenance. Make sure that the air vents
are not obstructed. The outside of the instrument is suitably cleaned using a soft, non-
fluffy dust cloth.
Instrument damage caused by cleaning agents
Cleaning agents contain substances that may damage the instrument, e.g. solvent-
containing cleaning agents may damage the front panel labeling or plastic parts. Never
use cleaning agents such as solvents (thinners, acetone, etc), acids, bases, or other
substances.
