Pickering Intros Versatile New MUX
Solid-state multiplexer.
Clacton on Sea, UK — Pickering Interfaces is expanding its range of PXI switching products with the introduction of the 40-682 Solid State Versatile MUX.

The 40-682 is an equivalent to the company's 40-612 Versatile MUX but uses high performance solid-state switches having a long service life, no switch bounce, and low on resistance. The "on" resistance of each multiplexer is typically just 3.2Ω, significantly lower than any other PXI solid-state switching module. Use of FET switches in the design ensures that the module can handle high currents without degrading the life time of the switches.

The new MUX can handle continuous currents of 0.25A and pulse currents of 0.75A for 100ms — enabling the multiplexer to switch reliably when connected to capacitive loads. Switch voltage rating is specified at ±40V. The versatile switching arrangement allows users to operate the new unit in a variety of configurations ranging from 8 banks of 16 channel 1-pole multiplexers to 1 bank of 128 channel 1-pole multiplexer. Two-pole switching is supported by the same module with configurations ranging from 8 banks of 8 channels to 1 bank of 64 channels.

The 40-682 is supported by VISA and Kernel drivers that provide fast control of the switching system. Switching time, including the driver, is typically just 80µs with a bounce free rise time of less than 20µs.

The MUX is especially suitable for a variety of applications where fast operation and long service life is required. It offers the lowest on resistance of any solid state switch available in the PXI format. The 40-682 can be configured to perform 4 terminal resistance measurements using a DMM quickly and accurately at the highest current capability of the DMM with low measurement errors.
