Model 4200A-SCS Parameter Analyzer Reference Manual Section 13: LPT library function reference4200A-901-01 Rev. C / February 2017 13-137pg2_initThis command resets the pulse card to the specified pulse mode (standard, full arb, or Segment Arb) and itsdefault conditions.Usageint pg2_init(int instr_id, long mode);instr_id The instrument identification code of the pulse card, such as VPU1 or VPU2mode The pulse mode:• Standard pulse: 0• Segment Arb: 1• Full Arb: 2Pulse modesStandard, Full Arb, Segment ArbDetailsThis command resets both channels of the pulse card to the default settings of the specified pulsemode. The default settings for each parameter are listed in the table below.If you want to reset the pulse card for the presently selected pulse mode, use the pulse_initcommand.Standard pulse defaults Full Arb and Segment Arb pulse defaultsPulse high and pulse low = 0 VSource range = 5 V fast speedPulse period = 1 μsPulse width = 500 nsPulse count = 1Rise and fall time = 100 nsPulse delay = 0 sPulse load = 50 ΩPulse trigger source = SoftwarePulse trigger mode = ContinuousPulse trigger output = On*Trigger polarity = PositiveComplement mode = Normal pulseCurrent limit = 105 mAPulse output = OffSource range = 5 V fast speedPulse count = 1Pulse delay = 0 sPulse load = 50 ΩPulse trigger source = SoftwarePulse trigger mode = ContinuousPulse trigger output = Off*Trigger polarity = PositiveCurrent limit = 105 mAPulse output = Off* Turns on when a pulse is initiated with pulse_trigExamplepg2_init(VPU1, 1)Resets the pulse card to the Segment Arb pulse mode and its default settings.Also seepulse_init (on page 13-144)
