LB180

The LB180 is used to interconnect the LB302/3 with external signal generators (e.g. D/A-converter, waveform generator, K-Line, resistor decade…). There are 6 single-ended, 3 potential-free, or every combination of generators connectable. They can be switched through a relay matrix to the LC-bus (Low-Curent-bus). From there the signals can be connected to the LB990 input cards, which are also wired to the DUT (Device-Under-Test). All relays on the card are interlocked to prevent shortcuts if there are software errors. The 18 LEDs on the front show the currently used LC-bus channels and inputs/outputs of the card.
