4423 vs 4425 (non bnc+)

[Gaz_13]

I've currently got the older 4423 and I've chance of getting a used 4425 non bnc+ model.

Is there much difference between the two? Is it worth the upgrade?

Many thanks
Gaz

Hi Gaz, sorry for the late reply and thank you for the post

Before I waffle on, both of these scopes are awesome despite their architectural differences

I guess my honest answer would be, purchase the 4425 and keep the 4423 if this is a viable option?

If not, you will find the used price of a 4423 still holds up today which is testament to its ability when coupled to PicoScope 7 Automotive software

In terms of specification/performance, the 4425 is no different to the current 4425A (all be it without BNC+) which means (from a scope perspective) you would gain the latest specification

Major features of the 4425 which you will gain

Connect Detect:

Bandwidth limit (Hardware filter)

Specifications for the 4425A (same as 4425) can be found here https://www.picoauto.com/products/autom ... ifications with the "stand out" features to consider below:

• 200 V max input voltage (Reduces the need for attenuation)
• USB 3.0 for increased streaming rate
• Max sampling rate 400 MS/s
• Buffer memory 250 MS

You can download the product manual for you 4423 here https://www.picotech.com/discontinued where you can then compare all the specifications

I hope the above helps, take care…….Steve

Top job Steve,

Many thanks for the reply. I've gone ahead and bought the 4425 and up to now I still have 4423. Much to my wifes displeasure I'm a bit of a hoarder when it comes to diagnostic tooling so I may have to sell the 4423 to have a happy life.

Perhaps we should ask your wife to use the 4423 for a while?

I have no doubt once she sees the potential it will be allowed to remain in the fold

Good luck with that one

Take care......Steve

Thanks Steve,

She's not a fan of the "pico-scoping" as she calls it. Today it went to it's new home, a motorcycle repair shop. No doubt it will be a much valued piece of equipment.

Before it left I did have the idea of plugging in both scopes to the same laptop at the same time and running the pico 7 software. A little part of me was hoping for 8 channels to be displayed. Alas it was just another dream idea of mine.

Thanks for your help with one Steve, also thanks for producing lessons, written and videos one on Youtube. They have been very helpful.

Kindest regards
Gaz
