The Aeroflex/Tektronix/CDS 53A-336 is a high-voltage scanner card that routes and switches high-voltage signals in automated test systems. This reed relay scanner card provides sixteen 2-wire channels and integrates into the CDS 53/63 Series architecture for multi-channel signal routing and control in modular test configurations.
