2. Proceed in the same way for the remaining channels 2 through 8, as required
in your test setup.
3. Connect the port [DUT1] of the R&S
OSP-B157WX to channel 1 of your DUT.
4. Proceed in the same way for the remaining channels 2 through 8, as required
in your test setup.
5. For your companion device (which is connected to the [COMP] port of the
base module), connect the port [X1] of the R&S
OSP-B157WX to the port [X1]
of the R&S
OSP-B157W8 or R&S
OSP-B157W8PLUS.
6. Connect the port [RxOUT] of the R&S
OSP-B157WX to the port [Rx] of the
R&S
OSP-B157W8 or R&S
OSP-B157W8PLUS.

7. Connect the port [Rx] of the R&S
OSP-B157WX to the input port of your mea-
surement instrument, for example a spectrum analyzer or test receiver.
8. On the rear panel of the R&S
OSP-B157WX, connect the switch unit's RJ45
[LAN] port for remotely controlling the R&S
OSP-B157WX as described in the
OSP switch units. Note that this usage is differ-
ent from the
, where you must use the module's LAN port instead
of the switch unit's LAN port. Do not use the CAN port for controlling the
R&S
OSP-B157WX.
9. Connect the power supply connector to an isolated ground receptacle of your
mains grid. The supply voltage must be between 110
VAC and 240
VAC with
frequencies ranging from 50 Hz to 60 Hz. Within these ranges, the device is
