SYSTem:HELP:HEADers?

This query returns a list of all SCPI commands supported by the instrument.
Data is returned in IEEE 488.2 arbitrary block program data format as shown in
Figure 12-1
Figure 12-1
Each point in the trace is represented as an IEEE 754 32 bit floating point number,
made up of four bytes in the data block. The MS byte is transmitted first. Each
complete block is terminated by a line feed.
Commands are listed in alphabetical order.
