Command Reference This chapter contains reference information on programming AT525D with the SCPI commands. This chapter provides descriptions of all the AT525D's available RS-232 commands which correspond to Standard Commands for Programmable Instruments (SCPI) command sets, listed in functional subsystem order.
Page 30
For example, root:com3:com5 ppp; : root:com1 ppp The AT525D accepts the three forms of the same SCPI commands: all upper case, all lower case, and mixed upper and lower case.
Command Reference Header and Parameters The commands consist of a command header and parameters. (See the following.) For example comp:nom 100.0e3 Header Parameter Headers can be of the long form or the short form. The long form allows easier understanding of the program code and the short form allows more efficient use of the computer.
