LCMScope
Damian-Wieclaw
Limitless Common Mode Scope. Battery powered probe with fast ADC with FPGA and UART connection. Data acquisition takes place when the trigger signal is high, later data is sent via UART to the computer. Purpouse of this device is to make precise measurements for high common mode signals.
