Using CONFigure?
The following command:
CONFigure?
returns the measurement function configured by the last CONFigure or MEASure? 
command sent to the instrument. Sending 
CONFigure? after power is cycled 
generates a settings conflict error until 
CONFigure or MEASure? is sent.
For example:
CONF:FREQ 1.0E6, (@2) 
CONF?
returns (including quotes):
"FREQ +1.00000000000000E+006,+1.00000000000000E-004,(@2)"
which includes the function, expected value, (calculated) resolution, and channel. 
If a channel number is not specified in the 
CONFigure or MEASure command, no 
channel is included in the return string.
