Scpi（Standard Commands For Programmable Instruments - Saluki STB6684 Operation Manual

STB6684/A Operation Manual
to prepare the transimitted data or that errors exist on the instrument. As soon
as STB6684/STB6684A sends a SRQ service request signal, it will set the status byte
to 6. 6 bytes are RQS request service bytes and sometimes connects with serial poll to
act as the status byte. When STB6684/STB6684A enables the SPOLL command, it will
clear the RQS request service bit and the SRQ string. Each bit in a status byte will
enables a SRQ service request. User can shield the status byte to judge
which bit
TRIGGER (GET)
Trigger bus command. This command can be sent to a selected device or all listener
devices. It is necessary to assign STB6684STB6684A as a listener device firstly and
then set the trigger mode as bus trigger mode. Finally send trigger data.

Standard Commands for Programmable Instruments
SCPI is a new general command based on the IEEE488.2-1987 standard. (SCPI is the same as
TMSL, a system language for measurement tester adopted by HP.)
