Pico Tech TA131 vs Pico Tech MI103

[Trader]

I bought a Pico Tech TA131, but I received a "Pico Tech" MI103.  Are they the "same"?  Should I return it?

"This product has been superseded by the TA131."

"250 MHz Oscilloscope probe X1/X10
This passive high impedance scope probe has a 250MHz bandwidth and high frequency trimming. A two position slide switch allows attenuation of either x1 or x10 to be selected. Please note that the x10 function will not work with the ADC-10 or ADC-12 as the input impedance of these devices is not the same as a standard oscilloscope."

Hello,

I have a TA131. If you have a question, perhaps I can answer.

Best regards

I have no experience with the MI103 probe.

While I have no doubt that it could perform equally well as the TA131, there is a main difference.

MI103 has a separate HF-trim, which you have to get right before you can have a stellar performance from this probe.
By contrast, the TA131 has only the usual LF-trim and is an excellent HF-match for the SDS1000X-E series right out of the box.

To cut a long story short, you need to study the operating instructions carefully and will most likely need a good quality 1 MHz square wave with fast risetime (<3 ns) in order to adjust the HF-compensation correctly.
