The optional R&S TS-PXB2 backplane extension also uses the CAN bus. For the mod-
ules plugged there (only R&S TS-PIO3B or R&S TS-PTR permitted), GA4 and GA5
can also be configured via jumpers. For this reason, the optional R&S TS-PXB2 back-
plane extension behaves like a complete device for the purpose of the CAN bus.
is applicable to the optional R&S TS-PXB2 backplane extension:

If the optional R&S TS-PXB2 backplane extension is used in the R&S TS-PCA3, X10
(GA5) can remain set and X11 (GA4) can be plugged in the same way as on the main
backplane. In this way, the addressing range of the CAN bus is expanded to slot codes
0000 (slot A1) and 0001 (slot A2).
If the optional R&S TS-PXB2 backplane extension is used in the R&S TS-PCA3, the
R&S TS-PXB2 must be configured as a new "device" to prevent addressing collisions
with slots 1 and 2.

Switching the PSU
Signal PS-ON is used to switch the PSU outputs on and off. This is done by removing
Jumper 3 (see jumper field in Section 8) and replacing it by an external switch. Signal
PS-ON is available at expansion connector X80.

Line Connection and Power Switch
The line inlet and power switch are at the back of the CompactTSVP (see

Cooling
The R&S TS-PWA3 features a powerful cooling concept.
The slots at the front (optional in the Rear I/O area) are cooled by a vertical flow of air.
The four fans are located above the slots and are connected by inline contact connec-
tors to the backplane. The fan speed is regulated by the internal temperature.
For the rear I/O area, fans can be retrofitted through the R&S TS-RFAN option. The
supply voltage for this fan unit is tapped at the +12 V studs (
(sheet metal flashing).
The R&S TS-RFAN fan unit is especially required if
