DSO-2810F question

I have a DSO-2810F device and I'm trying to record a waveform of ~8MHz frequency. I can't seem to figure out how to actually record/view something at 100Mhz sampling rate. The record button is greyed out and nothing is displayed on the screen. I'm pretty new so I'm not sure if I'm missing something. Can I record a high-frequency waveform somehow?

Thank you for your question.

DSO-2810F does not support data streaming. Therefore it has to store the sampled data in its memory buffer first before slowly transfering the data to the PC. The record length is thus limited by the buffer size.

I am interrested in the LCR parts of multi-instrument , i download the demo but i have real trouble to calibrate it, it jump to 1% to "BAD" and sometime to "time out error" when sliding mic and volume control of the card . I tried hi and low impedance, no can do.

The LCR meter will check the quality of the signal returned by the Device Under Test. The test signal is sinusoidal. If the THD of the signal exceeds a certain limit or is too weak (which would affect the accuracy of the measurement), the "BAD" error will occur. The peak percentage of 1% showed that the signal was too weak. You can either increase the input gain of the sound card or increase its output volume to make the measured signal stronger to avoid the "BAD" error. The timeout error could also be due to the weak signal or discontinuity in the connection. It was too weak to trigger the oscilloscope which is set to single trigger mode under LCR mode.
