10-Channel Coaxial High Resistance Matrix Scanners
The model 4610A is a precision, 10-channel coaxial matrix scanner designed specifically for ultra-high resistance measurements. It was engineered with simplicity as the focus. The result: it eliminates the limitations of conventional relay-based designs.
A fully-coaxial signal path from input to output minimizes leakage currents and parasitic effects, enabling accurate measurements up to 1 TΩ with negligible uncertainty contribution. This gives your demanding laboratory environment stable, reliable and repeatable metrology-grade performance.
The 4610A improves measurement efficiency by eliminating manual lead changes when testing multiple resistors, significantly reducing setup time and operator error. Select channels from the front panel, or remotely through the IEEE-488 (GPIB) interface for seamless system integration.
When used with Measurement International’s 6000C Automated Resistance Bridge and 6600A High Resistance Dual Source Bridge, the system supports fully automated measurements, including unattended operation, scheduled testing, and improved laboratory throughput.
High-isolation N-type connectors and fully-floating channels ensure optimal measurement integrity. Front panel LED indicators provide clear channel selection status, while an integrated protection feature prevents simultaneous connection of a single input to multiple outputs, safeguarding both the device under test and measurement system.
The robust mechanical design and precision switching architecture ensure long-term reliability and consistent performance, even in continuous operation environments. This makes the 4610A an ideal solution for national metrology institutes, calibration laboratories, and high-precision manufacturing facilities requiring repeatable, high-confidence resistance measurements.
