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 amplitude is 22 volts, which is correct
Shows DSO112. The analog part of the DSO112A is very poor. I'm not happy with the purchase.
