The Keithley two-pole, 6 row by 16 column matrix card. It can connect up to six differential instrument channels to any combination of 16 DUTs. Any row can be connected to the series 3700A mainframe backplane by using the analogue backplane connection relays. This allows for easy matrix column expansion. A matrix of up to 6 rows by 96 columns can be supported within a single model 3706A mainframe. Analog backplane connection relays provide easy column expansion
