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.
