4.24.8 :SIGNal
:ARM[:SEQuence[1]][:LAYer[1]]:SIGNal Bypass arm control source
:ARM[:SEQuence[1]]:LAYer2:SIGNal Bypass scan control source
:TRIGger[:SEQuence[1]]:SIGNal Bypass measure control source
Format :arm:sign
Description These action commands are used to bypass the specified control source and also when you do not wish
to wait for the programmed event. Keep in mind that the instrument must be waiting for the appropriate
event when the command is sent. Otherwise, an error will occur and this command will be ignored.
When this command is sent, the specified control source will be bypassed. This will allow operation to
continue.
Note that :SIGNal is not an instrument setup command. As soon as this command is executed, it will at-
tempt to bypass the control source.
Programming example OUTPUT 716; “:trig:sign” ! Bypass measure control source.
4.24.9 TCONfigure commands
:PROTocol <name>
:TRIGger[:SEQuence[1]]:TCONfigure:PROTocol <name>Specify Trigger Link protocol
Parameters <name> = ASYNchronousAsynchronous Trigger Link mode
= SSYNchronousSemi-synchronous Trigger Link mode
Format :trig:tcon:prot <name>
Defaults Power-up Saved power-on setup
*RST ASYNchronous
:SYSTem:PRESet ASYNchronous
Query :PROTocol? Query programmed Trigger Link protocol
Short-form format: :trig:tcon:prot?
Response message: ASYN or SSYN
Description This command is used to select the protocol for the measure layer Trigger Link. With ASYNchronous
selected, separate trigger lines are used for input and output triggers. With SSYNchronous selected, a
single trigger line is used for both input and output triggers.
Note that the arm and scan layers only use the asynchronous Trigger Link mode and therefore, do not
have to be selected.
Programming example 10 OUTPUT 716; “:trig:tcon:prot ssyn; prot?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Selects semi-synchronous Trigger Link protocol, and then queries the selected protocol.
