:SBUS:SPI:CLOCk:SOURce?
Functional description：

This command is used to set SPI bus clock source of the oscilloscope.
<Dx>: It presents the oscilloscope has LA function and it can set D0-D15 channel as the bus decoding source.
Return format：

Query returns {CHANnel1|CHANnel2|CHANnel3|CHANnel4|<Dx>}.
