HI @Paul.1949,

I apologize for the long delay; the engineer who is best able to help you, @attila, is out of the office until this coming Monday, Feb 12 (which I didn't realize when I initially moved your question). Looking at the options in the WaveForms software, it appears you can set the range from 100 uV/div to 4V/div when set to a 1x attenuation, but I'm not certain if that directly correlates with input sensitivity since the options in WaveForms for the AD2 also exceed the quoted values from the reference manual.

Again, I apologize for the delay and the confusion.

Thank you,
JColvin

Hi @Paul.1949

You can find such informations in the WaveForms application Help tab.

Electronics Explorer

4. Oscilloscope

The Oscilloscope has four channels with AC and DC input.

Specifications:

  • The input bandwidth is 100 MHz and the ADC frequency is 40 MSps.
  • The DC inputs have an impedance of 9.3 MOhms in parallel with 10 pF.
  • The AC inputs have 100 nF filter capacitor.
  • The input voltage is from -20 V to 20 V.
  • The ADC is 40 MHz, 10 bits, with adjustable resolution from 800 uV to 40 mV.
  • The offset is adjustable from -20 V to 20 V.

Adding that the EExplorer board scope inputs have about 60 range/resolution steps.

 

Analog Discovery 2

4. Oscilloscope

The Analog Discovery 2 has two differential oscilloscope input channels.

Specifications:

 

Low gain

High gain

Range

 > 500 mV/div

 <= 500 mV/div 

Differential input voltage

 N/A

 -5 V to +5 V

Common mode input voltage

 N/A

 -20 V to +5 V

Positive and negative input voltage to GND

 ±25 V

 N/A

  • The 0.5dB input bandwidth is 10 MHz.
  • The positive and negative inputs have an impedance to ground of 1 MOhm in parallel with 24 pF.
  • The ADC is 14 bits and 100 MSps, Analog Devices AD9648.
  • The absolute maximum input voltage is ±50 V.
  • The buffer can be up to 16 kS (default is 8 kS) on two channels.
  • The inputs have two gain stages, with ~3 mV and ~300 uV resolution. See the table below:

Thank you both for your replies and the information provided. I have decided to purchase an Electronics Explorer kit.
