130 Keysight 53210A User’s Guide
– trigger source
IMMediate sets a continuous trigger signal. By default,
CONFigure sets the trigger source to IMMEDiate.
– trigger source EXTernal sets the trigger source to an external trigger applied
to the rear panel ‘
Trig In’ BNC connector.
– trigger source
BUS causes the instrument to be triggered by the *TRG command
received over an IO interface.
Trigger Source Example
//configure for frequency, set system trigger parameters
CONF:FREQ 5E6,0.1,(@2)
TRIG:SOUR EXT // trigger source external
System Trigger Slope
When the system trigger source is set to
EXTernal, the triggering slope (edge) of
the signal is set with the command:
TRIGger:SLOPe {POSitive|NEGative}
TRIGger:SLOPe? (query form)
- trigger slope POSitive selects the signal’s rising edge, and trigger slope
NEGative selects the signal’s falling edge. The signal is applied to the
‘Trig In’ BNC. By default,
CONFigure sets the trigger slope to NEGative.
