| Playing with the Bodnar Pulser |
| (1/1) |
| BillyO:
The mailman (finally - it only took a month between the UK and Canada!) delivered my Bodnar pulser yesterday afternoon and I had some fun using it to look at rise times on some of my scopes. For each of the Siglent scopes I used the internal measurement and using cursors. I find that with some signals the cursor method is more accurate. However, this thing produces a pretty good square wave so keeping a couple of cycles in the sample should allow the scope to make decent measurements. For the "improved" SDS1104X-E I got 1.67ns via internal measurement and 1.72ns via cursors. Not bad for a $500 unit. Note the little rise drung the top of the square wave. This does not happen with signals that have slower rise times. :-// For the "improved" SDS2104XP I got 686ps on internal and 660ps using the cursors. The little bit of jitter on the pulser made the cursor measurement a little vague. And just for fun I tried it on the under appreciated Hantek 6074BC with a single channel enabled and got 1.60ns! How is it Hantek can make a pretty reasonable USB scope then fail so hard making standalone scopes? Edit - For some reason I can't add the screen shot for the Hantek. I get a "Your attachment has failed security checks". :-// Okay, figured it out. it has an unusual jpeg format. Fixed it... |
