Amazing information on this exciting and also important topic! Very well explained! THX! :-)
I purchased Rigol’s MSO5074 & unlocked the full bandwidth including all other features. I was able to measure 821ps rise time with the included PVP2350 passive probes, I’ve read on various forums, using an active probe the MSO5k can achieve a hair or two faster than 700ps RT, this with one channel, channel 1 or channel 3 on the MSO5k. For my purposes the MSO5k is a bit of overkill though I deal mostly with digital signals & the 350+ MHz BW will be quite useful.
Thank you very much for that review, this helped me to decide whether should I buy Hantek or not. I definitely decided to give that beast a chance.
I've clicked the thumbs up although this video made me sad. I cannot hope to own the Hantek nor the Siglent scopes. I must content myself with the 1013D. So I am constantly on the lookout for videos about how I could make use of it. Thank you for taking time and making the effort to teach.
that's what I was looking for! great video, thank you!
Very nice test!.. very well explained.. i never understood this methode, get it now...Thanks!
Thank you! I just got the Hantek 5102p myself. Glad to see the result you have come up with. Definitely worth the price!
My Hantek DSO5102P was excellent (the new owner also agrees with that) , I learnt so much using it, I hesitated to sell it, but I have a small space and it's full!
Too advanced for me at the moment Bill, but thanks for doing this.
I think manufacturers need to explicitly list the digital and analog bandwidths. Most bandwidth specs I see listed are analog. Given this is a digital approach based on signal accuracy that means alot of specs are false advertising. I have a dso138. I put a 1MHz square on it from a heathkit scope calibrator and it could read the frequency with some bouncing around . The output was less than 3 volts peak fixed. It could lock onto the 200khz. I will have to try this with the Velleman k7105 I have that was expensive when new.
Was looking at the Fnirsi 1014D and 1013D but found they both performed well below the specifications listed. I decided on the Owon HDS2202S, which is smaller and has better specifications but for a higher price. I feel that the Fnirsi products would sell better if the reviews did not suggest looking for something else for a similar price and compareable stated specs.
I've heard the Siglent SDS1104X-E uses the same "front end" as it's 200 MHz brother the SDS1204X-E. That would explain why it has higher scores. Economies of scale...
I need this segment
Did you get rid of the Hantek 2D72? I didn't see a bandwith test on it. Anyways for the money the Fnirsi still is decent. Most people who test up in the really high speeds should plan on buying more than a 140.00 scope.
Exactly, the budget test gear is fine for us hobbyists!
I was was running out of space, so I sold a few items, including the 2D72, the new owner is delighted with it, so all good!
Love how you Brits call everything "beastie".
