I'm actually surprised; the CC65 is lightyears better than the other piece of crap. I dunno about repeatability or accuracy or anything that matters, but I couldn't get the other probe to do even this...
I have the SDG2122X connected with some mini-grabbers to a piece of copper wire going through the current probe. Settings are 1kHz, 1Vpp. Probe set to 100mV/A.
ETA: ignore the filename, the last screenshot has averaging turned off.
KungFuJosh:
The low mA range on the CC-65 is mediocre, but better than the previous piece of junk.
Switching to the 10mA/V setting, the CC-65 was pretty consistent with the DCA stepping through to 6A.

One more thing:
The termination impedance is not 50 ohms, as far as I can remember regarding the CC-65.....
KungFuJosh:
Their amazing manual says typical load is 10kΩ.
Here's a capture with DC1M on CH1.
