Analog Bus Backplane
To simplify cabling, the R&S TS-PWA3 contains an analog bus with 8 signals. The ana-
log bus backplane is located in the front above the cPCI backplane. A special layout
meets the need for high crosstalk damping and low capacitance of the signal lines to
GND.
The C module (2 mm connector system) is used as the connectors (X1...X16). Plug-in
modules with no analog bus connector access the analog bus via a 26-pin connector
(X22) and R&S switch modules. Signals IL1_x and IL2_x (Instrument Line) are passed
from slots 5 to 16 to connector X22.
The analog bus signals pass from connector X21 to connector X2 at the back of the
R&S TS-PWA3 (see
Chapter 4.4.2, "Connections at the Rear"
electrical characteristics of the analog lines are:
●
Voltage 125 VDC max.
●
Current 1 A max.
