    Medlab—U/4C501 Biologic Signal Collection systems

    Newly added and main improving points
    ①Adopt high resistance(10E12Ω , 3pF), low nose. low drift 8i high function’s amplifier fuse to be ready, so it has such advantages as strong anti—interference, good linear degree and high measuring accuracy.
    ②Adopt USB 2.0 structure to transmit data, so its velocity is more high, and guarantees data’s continuous collection.

    ③Add 9 stage Besil low-pass wave filter newly, bi close to ideal condition
    ④Add 50Hz hardware wave frame circuit and datum tracing circuit newly
    ⑤Enlarge inputting electrical level’s scope to ±1.2v ,it’s very important to this condition that there is higher polarization voltage though the signal is very weak.
    ⑥Magnifying times is from 1,2,5,to 5000 so it can adapt to many kinds of signals.
    ⑦When outputting voltage is to 100v outputting current is to 100ma from electrical stimulator, it will separate light from electricity and be safe.
