Remarks
 For VerticalScale, refer to the :CHANnel<n>:SCALe command. For OFFSet, refer to
the :CHANnel<n>:OFFSet command.
 For RS232 decoding, only when the Rx source is enabled, can you set the threshold.
 For SPI decoding, only when the MOSI source is enabled, can you set the threshold.
Return
Format
The query returns the threshold of the specified decoding source in scientific notation.
Example
:BUS1:THReshold 2.4,PAL /*Sets the threshold of the PAL decoding source to 2.4 V.*/
:BUS1:THReshold? PAL /*The query returns 2.400000E0.*/
