Controlling the Source Remotely
ASE Broadband Light Source
37
Command Structure
An SRQ is forced when a bit in the Status Byte register goes from 0 to 1 and
the corresponding SRE mask bit is set. If an SRQ is forced, the RQS bit is set
to 1 and will remain there until read by a serial poll –even if the reason or
condition causing the service request no longer exists. Similarly, if a serial
poll reads the RQS, it is reset to 0, whether or not the condition causing the
service request still exists.
Command Structure
The GPIB and RS-232 commands follow the guidelines determined by the
Standard Commands for Programmable Instruments (SCPI) consortium.
For example, the following command syntax is used to activate or
deactivate the source.
SOUR:POW[:STAT]<wsp><Boolean>
➤
SOUR, POW and STAT are keywords that define the function of the
command.
➤
[ ] indicates that a keyword or parameter is optional.
➤
<wsp> indicates that a space is required ("wsp" stands for "white
space").
➤
<Boolean> indicates the command parameter.
➤
Keywords must be separated by a colon.
