53220A/53230A Input Signal Conditioning 4
Keysight 53220A/53230A User’s Guide 151
For single-channel time interval measurements, SLOPe/SLOPe1 sets the edge for
the start event and SLOPe2 sets the edge for the stop event.
CONFigure and MEASure do not change the slope setting. Following a reset
(*RST) or instrument preset (Preset), the positive (rising) slope is selected.
Input slope example
//set the threshold slope
CONF:FREQ 1E6, 0.1, (@1) // measure 1 MHz signal
SYST:ALEV:FREQ 10E3 // set minimum auto-level frequency
INP:IMP 50 // set impedance to 50 ohms
INP:RANG 5 // set range to 5V
INP:COUP AC // set AC coupling
INP:LEV:REL 70 // 70% threshold level
INP:SLOP POS // trigger on positive slope
