- I review the new Micsig MDP701 150MHz differential probe, sponsored by Micsig and Appvision.
I just the noise floor, CMRR, bandwidth and basic accuracy of the Micsig differential probe.

Micsig MPD701 150MHz High Voltage Differential Probe: defs.link/?u=4a0b843
The MDP701 is almost identical to the MDP700, MDP1500, MDP1501, MDP3000, and MDP3001, with the only differences being the bandwidth (either 100MHz or 150MHZ) and maximum input voltage of the differential probe (70V/700V, 150V/1500V, or 300V/3000V).
I really appreciate the donations and support I get from my Patreon Supporters and CZcams Members, donations really do help me to make content for the channel and buy broken test gear, this hobby gets expensive !: defs.link/?u=fcb3a1

One of those is definitely on my list, I dithered long enough to now be looking at the new model, some benefit to dithering I guess
No, most differential probes are certainly not isolated. They are simply high impedance to ground for both inputs. I don't have that new model probe, but I have the Micsig DP10007. The specification for it is 4 M ohm from ground to each input or 8 M ohm differential impedance. You can measure this from input to the shell of the BNC. The Micsig specs for new MDP probes are either 8 M or 10 M to ground, and double that for the differential impedance depending on the model.
Yes, the cardboard box thing is naff. All they need is a new insert for case they use for the older type differential probes and the current probes.
I just received the 1502 probe (4/29/2024) and it came with a plastic case.
I read an article in an old magazine that stated RMS reading meters may not be perfectly accurate if the AC waveform is not a perfect sinewave. On the scope, I can see a bit of distortion.
I think it is more of a problem for AVERAGE reading meters, rather than RMS reading.

Well, the article was written in 1954 so perhaps the equipment was not as robust as today? I don't know. 😅
Its actualy the other way round as a true RMS meter will be accurate for non sinusoidal waveforms whereas the cheaper Averaging meters make certain assumptions about the waveform and take samples and average those ignoring polarity. If you take the average of a pure sinewave it will of course be zero, I may have botched that delivery but the essence is there. Maybe someone out there can explain better than me !!
at 9:30 your discussion of the RMS value being a bit off spec.. the waveform on the scope, to my eye, doesn't look like the cleanest sine wave. The waveform peaks look like they flatten off somewhat. The RMS value of a distorted sine wave won't be the same as a pure sine wave, and could read a bit higher if the peaks flatten, even if the pk-pk voltage is the same on both waveforms. Just a thought.
Definitely right. Many scopes/meters 'estimate' the RMS by taking the PP voltage (which is relatively easy to detect from a waveform with a peak detector) and multiply this by 2sqrt(2). This is only of course correct for a pure tone sine wave.
'True RMS' meters calculate the power of the signal, which is what the RMS value actually means. It is very interesting how some high precision RMS meters do this ! They let the input waveform literally heat up a resistor, and measure the thermal dissipation with some clever tricks. RMS measurements are a fascinating subject in itself.
ooof the price tho
Hmmm - yea
