3.3.3.3
Power Backplane
The use of a second cPCI PSU in slots A1, A2 requires the optional Power Backplane
(conforms to standard PICMG 2.0). From the Power Backplane, a cable with three con-
nectors leads to a 24-pin ATX connector on the cPCI backplane. The three connectors
are as follows (see also
Chapter 8, "Interface Description"
Description):
●
X12, 20-pin
●
X13, 10-pin
●
X16, 4-pin
The second PSU can be used to boost the power of the standard PSU when connec-
ted in parallel. Alternatively it can be used to supply the device on test.
3.3.3.4
Backplane Extension R&S TS-PXB2 (Option)
The R&S TS-PXB2 option expands the Test System Versatile Platform R&S TS-PWA3
by 2 CAN bus slots (A1 and A2). It can be integrated ex works only.
The two slots are intended for the R&S TS-PIO3B or R&S TS-PTR options. The R&S
TS-PIO3B is an 8-channel, 8-bit Open Collector Digital I/O card with additional func-
tions.
The R&S TS-PTR is a passive feedthrough circuit board. It can be used to feed as
many as 24 signals through the device.
Ports 5, 6 and 7 of the R&S TS-PIO3B in slot A1 are routed to connector X1 on the
rear panel.
Ports 5, 6 and 7 of the R&S TS-PIO3B in slot A2 are available on connector DIO on the
rear I/O slot A4.
