After following the discussions and trying to decide if I should go with the A or B version, I decided for the economic more bang for the buck A-Version.
Last week I got it delivered so I wanted to check the performance myself. The results are almost too good to be true, so I would like to know if you agree with my test setup.

SDG1032X as source, feeding a BNC-connector through 5 loops on the current probe clamp into 3x150 Ohms. SDS1204X-E Channel 1 Voltage of 50 Ohm load resistor, 10x Probe, Channel 4 CP2100A 2x (because of the 5 turn coil)

During measurement, I maintained 2,50V RMS over the load resistor, and measured the current as RMS (nominal 50mA)

This picture shows the voltage and current @800kHz, the nominal bandwidth of the CP2100A.

To me this looks much better than the specs, is my setup suitable for bandwidth measurement?
