Triggering and Gating 5
Keysight 53220A/53230A User’s Guide 163
– 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.
Trigger slope example 
//configure for frequency, set system trigger parameters
CONF:FREQ 5E6,0.1,(@2)
TRIG:SOUR EXT  // trigger source external
TRIG:SLOP POS  // trigger slope - positive
System trigger delay
The delay between receipt of the internal or external system trigger signal and the 
start of the first measurement (Figure 5-1) is set with the command:
TRIGger:DELay {<time>|MINimum|MAXimum|DEFault} 
TRIGger:DELay? [{MINimum|MAXimum|DEFault}]  (query form)
– specifies the delay in seconds. Delays between subsequent measurements (i.e. 
multiple readings per trigger - see SAMPle:COUNt) are set with the 
SENSe:GATE:STARt:DELay commands. CONFigure and MEASure set a 
default delay of 0.0 s.
Trigger delay example
//configure for frequency, set system trigger parameters
CONF:FREQ 5E6,0.1,(@2)
TRIG:SOUR EXT  // trigger source external
TRIG:SLOP POS   // external trigger slope - positive
TRIG:DEL 1   // 1s delay after trigger received
