**Q:**When using 8-channel sampling, it was found that waveforms also appeared when the D7 channel was not connected.

**Q:**Why is the floating CH7 waveform noisy during 8-channel acquisition?

|

**A:**This is a problem to be solved, but this problem will not affect the sampled waveforms, and the waveform can still be acquired normally after connecting an external signal to the D7 channel.
|

**A:**This issue is fixed in `slogic_combo8_pack_202608121500.bin`. [Update to this release or a newer one](./update_firmware.md). A floating input can still pick up environmental noise, so verify acquisition with a known high or low level or an actual signal instead of using a floating channel as a reference.
