The PicoLog 1000 series units might be of interest - using the PicoLog software, you can capture data at 1Ks/s per channel but it probably won't be suitable for a parastic frequency of 10KHz, although this might be feasible using the software development kit as the maximum streaming rate is 100kS/s shared by all channels.
You would have to scale the voltage down to a range of 0 to 2.5V - PicoLog has a scaling feature to allow you to scale the values back.
You can find further information and data sheets on the product web page:
Including the small terminal board, the PicoLog 1012 (10-bit, 12 channel) and 1216 (12-bit, 16 channel) are £105 and £159 respectively.
The alternative is to use two PicoScope 2204 devices. This is an 8-bit resolution 2 channel PC Oscilloscope devices which can also be used with our PicoLog software and has a bandwidth of 10MHz. As sampling would be limited to several milliseconds between samples using the PicoLog software, you would have to write your own software to capture the waveform with the parasitic frequency.
As the maximum voltage range for the device is +/- 20V, you would need to use attenuation probes such as the MI007 at x10 setting.
