The SMP2007A is designed for scanning multiple high voltage points to a common bus in either 1- or 2-wire configurations, either synchronously with an instrument (i.e., using triggers), or asynchronously with individualrelay control. Up to 144 2-wire (or 288 1-wire) channels can be accommodated in a double-slot VXIbus card (SMP1200) for maximum density, or mixed and matched with other SMIPII™ cards for flexibility. Applications include Hipot or cable breakdown testing.
When switching high voltages, the need for signal shielding becomes critical. The SMP2007A has been designed to include large shield planes to reduce crosstalk and voltage spikes to adjacent channels
