MSU Board
Channel switch (relay matrix with 48 channels)
Description
The MSU board is a relay matrix with 48 channels. It is used to connect the test points of a DUT to the measurement board of the test system. The signal to be measured is connected to a central point by switching one of the 48 reed relays and from there connected to the analogue bus via a second group of 8 relays.
Applications
Typical applications include automatic testing of electrical assemblies and devices. The advantage of MSU3 in comparison to semiconductor switches is the combination of high dialectic strength and switching capacity at low capacitance. It is suitable for other uses in addition to connecting test points with a measurement device.
- Short-circuit and connection test
- Signal feed
- Connecting test points to each other
- Controlled discharge of capacities
