Command Set Overview
The KPA500 provides a set of remote-control commands to control most functions and to allow
monitoring of the amplifier.

Command Format
Commands sent from the computer to the KPA500 are considered either GETs or SETs. GET commands
are used by the computer to get information from the KPA500; the KPA500 will then provide an
appropriate response message (RSP). SET commands are sent by the computer to change the instrument's
configuration or initiate an event. Commands with an incorrect format or an out-of-range parameter are
ignored. A SET can be followed by a GET to verify the new settings.
SET commands use 2 or 3 characters, optional data fields, and a terminating semicolon (;). Examples:
^BN05;
Computer selects xxm band
^OS1;
Computer sets OPER mode in KPA500.
Many SET commands have a corresponding GET command, which is just the command letters with no
data, plus the semicolon. The data format of the response message from the KPA500 (RSP) is usually
identical to the format of the SET data. Exceptions are noted in the command descriptions.
Characters sent to the KPA500 can be in either upper or lower case. The KPA500 always responds with
upper case. The KPA500 will respond to a null command, containing only a ‘;’ by echoing the ‘;’
character. This may be useful to make sure the PC is communicating with the KPA500.
