• At least one of the DCA-M channel's needs to be on (although the channel input data does not need to be connected)
• There has been at least one data acquisition. (:ACQuire:RUN or :ACQuire:SINGle)

Query Response

The query returns 9.91E+37 (NaN) if a DCA-M is not connected to the indicated slot.

Response	Description
valid clock rate	A valid clock rate. For example, 9.95300E+9.
0.000000000E+00	An attempt was made to acquire data, but there was no trigger signal (or very slow trigger) connected to the Clock In connector.
-1.000000000E+00	The oscilloscope channel is off. Even if there is no signal connected to the channel, the channel must be turned on.
9.91E+37	(NaN, Not A Number). A DCA-M oscilloscope is not connected to the indicated slot.
