DSO112A measurement accuracy is much worse than DSO112 accur

DSO112A measurement accuracy is much worse than DSO112 accuracy. Manufacturer reduced Noise due to deterioration in accuracy. The signal in the lower part of the screen is distorted and turns into a straight line. The photo shows the results of the voltage measurement Glow tube TV. The actual signal...

As it turned out, the Input Imprdance DSO112A is 1.5M ohm instead of the declared 1M ohm Oscilloscope DSO112 does not have such an error...
