Got the CP2100A at work, same results as the B version.
So if you could be happy with 800Khz bandwith, take this one and save lots of money.
Comparing to the rest who will "give" us 800Khz or less, the price is outstanding.
But I send it back, because the "B"s are on stock again and I want the 2.5Mhz....
Final Verdict...
Pros:
- Always in their specs what accuracy concerns
- Really good building quality, wants me to make a teardown
- Small clamp
- Outstanding bandwith for the price, 800Khz for 200, 2.5Mhz for 375 Bucks - You won´t find this anywhere.
- Good, not best, but really good low noise level for it´s range
- Offset could be manually compensating (up/down additional to the auto-zero function)
Cons:
- Small clamp, but a little "thick" for lower current measure (probably you must do some extensions to put the clamp onto it for measuring)
- Needs external power supply
- Accuracy always in the specs but it´s somewhere around 4..5%, others could do it better (but cost much more)
- No degaussing function ( but this you will find only on models starting from 3000 bucks )
This or nothing...
Either you spend 200/370 Bucks for them or you save your money until you can afford the hioki things under several brands, starting with 3K bucks and upwards.
You shouldn´t expect the less noise and precision like you perhaps know from tek probes.
It is usable with currents starting from 50mA/div.
If this fits your needs, buy it.
You musn´t spend more money.
Really good stuff !
