Hi,
https://www.eevblog.com/forum/testgear/350mhz-scope-2020/msg3056674/#msg3056674I decided to order one, take it to work and hopefully can directly compare to other probes we use.
100Apk, 2.5Mhz Bandwith….sounds nice.
Price is 375€ (Batronix), well, what do we get from others:
Rigol RP1002C for 1886€
Testec TT-CC990 for 1178€
R&S RT-ZC02 for 898€
Siglent CP4070A for 842€
None of them offers the claimed 2.5 Mhz bandwith, some offer more than 100Apk, some less.
But all got one thing in common:
They were unlikely more expensive.
Therefore, the Micsig is very interesting.
The Micsig, like all other I´ve linked didn´t got a degaussing function, like I know from our tektronix probes but also from the lecroy ap011 probe.
At home I got the Owon CP05+ Probe, for appx 190€ incl. VAT.
Well....hm....Ah, forget it, this thing is crap.
Bandwith is claimed by 200khz, in real it would be something around 100khz, very noisy, you could use this thing from 1A up.
Before I got the Hantek CC-65 Probe....God...
For it´s price, I expect the Micsig will do a better job than my Owon or Hantek, that´s for sure.
But what about to compare it with "state of the art" probes?
What we got on work are Tektronix Probes and Lecroy Probe.
Chances are given, I can compare the Micsig with them, if Time allows it.
So I would do a comparison between CP2100B, CP05+, A6302, A6303, AP011.
My greatest "fear" would be the noise level.
Using tek probes or the ap011 from lecroy, you have a really low noiselevel - Could the CP2100B have it too ?
Let´s find it out...
Missing degaussing function doesn´t concern me much, more important is the noise.
But first of all, I´ll send a offer request to batronix, it would be 3% off I guess.
But hey, taking all what you can get..
Nevertheless, the probe should arrive within the forthcoming week.
Any test suggestions ? Post it here.
DC current is self explaining, so no worries.
AC current I could measure up to 400hz.
Switching power current upt to say 10...20khz, depending on the DUT I could get on work.
To be continued..
