IM AQ6370C-17EN
Explanation
Because remote control via the GP-IB interface of the /AQ6375 complies with the IEEE
488.2 standard, it is not compatible with the conventional model AQ6317 (complying with
the IEEE 488.1 standard) as to the remote commands and internal actions.
However, by placing the instrument in AQ6317-compatible command mode, you can use
some of the AQ6317 commands. Status register operation also has compatibility with the
AQ6317. When you switch the command mode, it causes all the contents of the status
registers and queues and receive buffer and talker output buffer to be initialized.
Operation in AQ6317-Compatible Mode
The instrument operates as follows when it is remote controlled in the AQ6317-
compatible mode.
• The majority of AQ6317 control commands and talker commands are available.
• Talker data is output in the AQ6317-compatible format.
• To send multiple commands at one time, use a comma “,” as a separator.
• If receiving multiple query commands in a single line, the instrument outputs only data
relative to the last query command.
Switching Command Modes with Commands
The command mode can also be switched using the following GP-IB commands.
Commands to use when in AQ6370C, AQ6370D, AQ6373, AQ6373B, AQ6375 or
