PICO Technology TA189 AC/DC oscilloscope current probe Review 5mA~30A Low Noise

[Kiriakos GR]

PSU waveform this is most polluted with noise, it is in the nature of this technology to behave that way. 
Tomorrow I will run the last pack of tests, and this is Phase Shift stability and Min/ Max in all three loads.

The upcoming statistics will help me so I to evaluate my oscilloscope performance in contrast to the new scope (when ever I will get one).

Unfortunately for me and for GW Instek, I did hit a wall due the 8 bit resolution of my Oscilloscope.
I was feeling optimistic that by a special probe alone I could go further in power analysis. 

Even up to date (7-2023),  GW Instek this does not have ready any 12 bit scope so to compete in this market.
I am very bonded now with GW Instek oscilloscope user interface ( menu, buttons, and where its setting this is placed).

For now I will have to set a pause, and wait if in the future, GW Instek succeed to deliver 12 bit scope at a reasonable pricing.
Most other known vendors, still consider 12 bit Oscilloscope as huge BIG THING, and their pricing policy this is still unreasonable.

Few Chinese vendors, they did release 12 bit Oscilloscope, but my trust this is hard to be earned from brand names which does not have a serious European based network for sales and products support.

Fourteen months later and my enthusiasm in favor of TA189 AC/DC oscilloscope current probe, its still alive. 

In the world of digital power meter analyzer with 16 bit ADC, this TA189 it can deploy it full potential.
a) 16 bit ADC this has much lower noise floor.

b) TA189 AC/DC this has 100 KHz bandwidth, that is DC bandwidth of (medium in price range) digital power meter analyzer, and it can be used will all instruments which supporting EXT BNC input for a clamp probe.

c)  PICO Technology TA189, this probe has an history background as a product developed due a German and English collaboration.
ODM this GMC-I PROSys ltd, product model CP35.
And even Rohde & Schwarz liked this product design, and distributes it with model number R&S RT-ZC03.

Even within 2024, the technology in use at TA189, CP35, RT-ZC03, this is best in class as medium priced clamp probe.
Strong points: Measuring sensitivity, Noise immunity along 100 KHz bandwidth. 

The better clamp probe Class, are the ones priced at 5000 Euro or higher.
These has a more complicated electronic design, they require external PSU, they come at bandwidth of 50 MHz and 100 MHz.
They are tools for very specific needs regarding measurement and R&D.   

September 2024, I am exploring again all latest offerings as (medium in price range) digital power meter analyzer.
Any instrument not including EXT input, this gets out of my list of candidates.
