I have a technical inquiry regarding the measurement of analog signals with galvanic isolation. We're specifically interested in the frequency range from DC up to at least 1 GHz. I'm eager to understand the capabilities of your solutions in this area, particularly the lowest frequency cut-off you can offer. Is it feasible to achieve measurements that include DC, or is there a typical lower limit you encounter? Insight into this aspect would be extremely helpful for our ongoing projects, as we aim to enhance our signal measurement capabilities. Looking forward to your detailed response on this topic!
