Reportedly cost effective, the Model QMUX16X2 multiplexer interfaces test and measuring equipment to numerous signals and can measure two signals simultaneously. The multiplexer features 16 inputs and 2 outputs and is powered and controlled by a PC. It uses low-power reed relays and a USB controller in a DIN rail mount enclosure. Essentially, it serves as the missing link in a complex test setup. Additionally, it handles single or differential signals less than 10 MHz. The QMUX16X2 Multiplexer is priced at $249.
