Waveforms Voltage Level Does Not Match Measurement

[Abhijan]

I'm new to Analog Discovery and Waveforms. I'm using an Analog Discovery 2 with a BNC Adapter.

I created a 5V 100Hz square wave using Waveforms, but when I measured it using an oscilloscope, the Vpp of my signal was ~ 530mV. I also tried just sending out a DC value and measuring it with a voltmeter, same issue. It seems like there is a ~1/10th scaling of all the values. What could be the issue? Do I maybe need to calibrate the device?

Hi @Abhijan,

The first thing I would be checking with the 1:10 ratio would be the attenuation setting on the BNC probe. It's also worth ensuring that your two devices share the same ground connection.

Let me know if you my guess is not accurate to your situation.

Thanks,

Hi @JColvin,

Thanks for the feedback! I think that was accurate. I tried a separate BNC cable with no attenuation and it seems to be working! (I feel kind of stupid now lol)

Thanks!
