Each of the real time traces have corresponding REF traces (for example
FREQ1_REF or THDN2_REF) that can be set. Whenever any of the real time
reference traces are set, the real-time box automatically changes to a delta mode
for the current unit shown.
Example: TRAC:DATA FREQ1_REF, 100 sets the reference value for the channel 1
frequency to 100 Hz.
Units: The units of the data returned by the TRAC:DATA? query are fixed and do not
follow the UNIT commands.
