Appendix 2.3 Commands
2.3.6
HARMonics Group
The commands in the HARMonics group relate to the harmonic analysis function. This allow you to make the same settings and
inquiries as when using the HARMONICS key on the front panel and the corresponding menus. This group is only useful in case
your instrument is equipped with the /HRM option.
:HARMonics
:
HARMonics?
