### 3206 sensitivity

I am seriously considering buying a 3206 kit. However, the technical specification states a vertical sensitivity of +/- 100mV to +/- 20V/div. Elsewhere the sensitivity is stated as 10mV to 2V/div. Which is correct?
Also, the stated resolution is 8 bits - are 8 bits used at 100mV and also at 20V?

Hello,

To clarify the resolution, I will show you how to calculate A-D converter steps.

The calculation goes like this with only two variables to change.
A-D mV steps = Voltage range Ã· Bit resolution

Now, you will need to compute the bit resolution like this: 2x10^n where n=bit resolution. Next you will need to compute the voltage range. A Â±500mV range covers -500mV to +500mV, a range of 1000mV.

So the calculation now looks like this:
3.9mV = 1000mV Ã· 256 (2x10^8)

Hope this makes sense.

Best regards,
Michael

Hello Michael,

I hope you don't mind me jumping in here.

Your step calculation makes perfect sense except for one thing. How does 2x10^8 =256? I'm not familiar with the "^" symbol.

Thanks,

Michael

Hello Carl,

Sorry for my lack of ASCII codes, I was trying to represent 2 power 8 in symbol and used the carat symbol for lack of superscripts.

The calculator version would be like this: (2^8)
3.9mV = 1000mV Ã· 256 (2^8)

Sorry for the error.

Regards,
Michael
