Scope model ATTEN ADS1102CAL
I have been studying about OP Amps for several weeks but I am confused about what my scope is telling me. So I have a few fundamental questions.
1 - Poor Display.
1.a Notice the poor visual display of the waveform on channel 1 at 1V per division
1.b Wave looks better at 500mV per division.
Q. Would this just down to the “budget” quality of my scope or more, like mains hum?
2 - Looking at weak voltage signals
2.a CH1 96mV input to Op Amp. CH2 output of Op Amp of 1.28V.
The 96mV is derived from a voltage trimmer on my Analogue Development board.
2.b The same thing but voltage is derived from a very low value resistor GND side of a potential divider on a PC-SMPU.
While the numbers look ok (I think) the display is a mess.
Q Why? Am I suffering from not setting my scope up correctly or poor measuring conditions.
Thanks, Paul.
