Remarks
 POSitive: samples the data of the data channel on the rising edge of the clock signal.
NEGative:
samples the data of the data channel on the falling edge of the clock signal.
BOTH: samples the data of the data channel on both the rising and falling edge of the clock signal.
 If the clock channel is currently not set (refer to the :BUS<n>:PARallel:CLK command), you do not
need to use the command to set the edge type.
Return Format
The query returns POS, NEG, or BOTH.

Wherein, VerticalScale is the vertical scale of the specified
analog channel, refer to the :CHANnel<n>:SCALe command;
Offset is the vertical position of the specified analog channel,
refer to the :CHANnel<n>:OFFSet command.
