10. In the dialog that opens, enter the path name
Path-1
.
The path is stored in the switch unit's volatile memory. It can be switched now via
the "Path Switching" dialog in the user interface or via remote control commands,
for example, from R&S
EMC32 or R&S
ELEKTRA, by calling "Path-1".
11. At "Path Switching" > "Context Menu" > "Export/Import Paths", click "Export Paths".
12. Enter a filename for your path configurations export file and click OK.
All currently defined paths are stored in the switch unit's flash memory.
Activating "Path-1" performs the following actions (regarding
●
The activated OUT line "CH1" sets relays K1 and K2 to position 1.
●
The activated OUT line "CH7" sets relays K3 and K4 to position 1.
●
The activated OUT line "CH15" sets relay K7 to position NO.
●
The activated OUT line "CH16" sets relay K8 to position NO.

Input Ports of R&S
OSP-B103
The input ports of the module R&S
OSP-B103 are designed for LVC (Low Voltage
CMOS) logic, but can be operated with TTL level up to 5
V, as well.
Control circuits like the interlock loop in typical EMS test systems often use control vol-
tages up to 28
V
DC. You can connect the R&S
OSP-B103 input to circuits with up to
28
V, if you observe the following point:
