Risk of personal injury due to RF radiation being switched on
If the R&S OSP is used in a system or application that involves amplified RF radiation,
switching on the RF power of a generator or amplifier could lead to personal injuries, if
human exposure to this radiation is not prevented.
To avoid this risk, make sure that nobody is exposed to RF radiation, as soon as the
power is switched on. It is in the responsibility of the user to define the Power Up
condition of the modules R&S OSP-B101L and R&S OSP-B102L. Note the instructions
given above.
Per default the Power Up condition for the latched relays is set to
POWERUP:RESET
“ON
“.
The current setting can be read via SCPI command
CONFigure:POWerup:RESet?.
Refer to the operating manual for further information on the CONFigure commands.
5.2.17 I/O and supply Module R&S OSP-B158
The module R&S OSP-B158 is designed as a power supply and control module. It
consists of a 16 bit input, a 16 bit differential RS422 output and a power supply
connector. All ports are D-Sub connectors, male for input, female for output and power
supply.
On the left side of the module, there are four LEDs, labeled
+12 V
,
-12 V
,
+10 V
and
+28 V
. If all LEDs show a green light, the power is OK. If one LED is off, there is a
problem with the power supply of the corresponding voltage and probably the
maximum current is exceeded (see data sheet). In such a case, please turn off the
R&S OSP, disconnect any cable connected to the supply connector and turn the R&S
OSP back on and check the LED again.
The LED labeled EXT shows a green light, if a 3.3 V voltage is supplied at the input
connector pin 17 (AUX-IN), see
chapter 3.3.8
