Geographical Addressing
Each slot is assigned its own digital slot code (GA code). This code is used internally to
directly address the µC.
3.4.5.3
System Clock
A local quartz crystal generates the 10 MHz system clock for the system (PXI_CLK10).
Alternatively a very accurate reference clock can be fed in across X30. Jumper JP2 is
used to select an internal or external clock source. The jumper functions are shown in
Chapter 8.4, "Interfaces of the R&S TS-PSYS2"
3.4.5.4
Signal Looping
A number of signal lines are looped from connector X30 to connector X20. These are
used to input/output Rear I/O signals (e.g. for the R&S switching modules R&S TS-
PMB, R&S TS-PSAM)

Local Signal Outputs
Special signals of the R&S TS-PWA3 can be connected to connector X20 (Rear I/O)
with the help of jumper field X40. The jumper functions are described in
"Interfaces of the R&S TS-PSYS2"
Jumpers only permitted when system voltages are < 60 VDC.

The bus-lines of the CAN2 Controller are available for the X30 connector (CAN2_H,
CAN2_L).
In addition, with the jumpers on X40, the lines can be brought to the front-module R&S
TS-PMB in the slot 15, see
