FIGURE 4-3. TYPICAL EXAMPLE OF INTERFACE CARD PROGRAM USING SCPI COMMANDS
4.4 CIIL PROGRAMMING
The CIIL command language is used on early models of Kepco power supplies and controllers.
The command functions are included here for compatibility with other equipment programmed
with CIIL commands. The CIIL command set for the Interface Card is defined and explained in
Appendix C.
