Monitoring Communications Bus

Postby CoreControls » Wed Oct 26, 2005 6:15 pm

I would like to monitor a communications bus set for 19.2 Kbps. I am interested in the ADC-40 or PicoScope 2202. Is one more suitable than the other with respect bandwidth or sampling rate, or will both work well?

Thank you for your post.

The ADC40 has a maximum sampling rate of 20kS/sec, a bandwidth of 10KHz. The 2202 has a sampling rate of 20MS/sec, a bandwitdh of 2MHz.

The 2202 is far better as your bit rate is approaching your maximum sampling rate. You will get better, longer samples with the 2202 as the ADC40 has no memory or clock onboard.
