Low & High Speed mode: EmStat Pico

What does low speed and high speed mode mean for the EmStat Pico?

  • The EmStat Pico module works at two different modes; 
    Low Speed mode: for scan rates up to 1 V/s or a bandwidth of 100 Hz.
    High Speed mode: for high scan rates and frequencies.

    Hybrid mode: combination of both modes to increase .

    The different modes have following limitations:
