About

The J-Testr 4-channel AC measurement module enables the standard J-Testr ADC/DAC peripheral card to be utilised to measure AC true RMS voltages, and frequencies up to 300kHz. With high accuracies up to the full working bandwidth, the module is suitable for most functional test applications that require accurate AC measurement.
Picture
The module has 4 multiplexed AC inputs that are 100% compatible, if required, with the standard J-Testr ADC/DAC peripheral card’s external multiplexer scanning mechanism, allowing the user the ability to simply read the measured result from the appropriate configured scan channel results register.
​​​
The compact and easy to mount module measures only 40mm x 35mm, minimising the space required on the J-Testr interposer card. The connector pin-out is designed to easily route into the ADC/DAC peripheral card with minimal effort and maximum efficiency.
