Normally the command BACKEND has 5 parameters: backend name, part number, resolution [MHz], bandwidth [MHz], and frequency shift [MHz]. Option /RECEIVER connects this backend part to a receiver. This receiver must have been previously specified with RECEIVER.
For some backends the resulution, bandwidth, and/or frequency shift are fixed and a shorter syntax is possible, see, e.g., the example above for the continuum backends. See the HELP for complete information.
/DISCONNECT disconnects a backend (part) while retaining its parameters.
/CONNECT (re-)connects the sepcfied backend (part).
Normally the continuum backends are used for pointing and focus.
