:ARM[:SEQuence][:LAYer]:SOURce
Syntax :ARM[:SEQ][:LAY]:SOUR
Form Set & Query
Description Specifies when the generated signal is output immediately, by
manual start or depending on an external signal at the Start In
connector.
Parameter IMMediate|MANual|EXTernal
The instrument provides the following start modes:
•IMMediate
The generated signal is always available at the outputs (assumed
that the outputs are enabled).
•MANual
The generated signal is output after Start at the instrument
panel is pressed.
•EXTernal
Select this start mode to send the generated signal to the
outputs depending on the external signal applied at the Start In
connector.
You can define the following parameters that the external signal
must meet:
– Threshold (voltage)
Set the threshold with “:ARM[:SEQuence][:LAYer]:LEVel” on
page 91.
– Termination voltage
Set the termination voltage with
“:ARM[:SEQuence][:LAYer]:TERM” on page 94.
– Edge (rising/falling)
Set the edge with “:ARM[:SEQuence][:LAYer]:SLOPe” on
page 92.
*RST value IMMediate
Example Set the start mode to external.
