Combining Commands
You can use a semicolon (;) to combine commands and queries. This oscilloscope
executes coherent commands in the order it receives them. When you coherent
queries, the oscilloscope will combine the responses into a single response
message with LineFeed (0A) for each command . For example, if the frequency and
amplitude of the signal are equal to 100kHz and 1V, the command
:MEASure:FREQuency?;:MEASure:VAMPlitude?
returns the message
100kHz 1v
*: Please note that a LineFeed (0A) message terminator will be added behind each responded
command.
Therefore the return message of “100kHz 1v” should be exact looked like as “100kHz 0A 1V 0A”
