Signal generators are often used in automated test environment applications. The replacement of these instruments, due to malfunction or standard replacement procedures, requires special care. There must be compatibility between the existing part and the replacement part, at least in regard to the electrical and remote-control features. Older instruments often use a proprietary remote-control language; therefore, direct replacement may require language emulation capability in the software of the replacement part.

To meet these requirements, the R&S signal generators are shipped with a "language emulation" feature. By selecting the desired "language emulation," the signal generators act as the original instrument. This application note describes in detail how the different remote emulation modes of the R&S series SMA100A, SMB100A, SMF100A signal generators can be used.
