Arguments
sweepType, whether the frequency will sweep from startFrequency to
stopFrequency, or in the opposite direction, or repeatedly reverse direction.
Use one of these constants:
PS6000_UP
PS6000_DOWN
PS6000_UPDOWN
PS6000_DOWNUP
operation, selects periodic signal, white noise or PRBS:
PS6000_ES_OFF (0)
produces the waveform specified by waveType.
PS6000_WHITENOISE (1)
produces white noise and ignores all settings
except offsetVoltage and pkTopk.
PS6000_PRBS (2)
produces a pseudo-random binary sequence
(PRBS) and ignores all settings except
offsetVoltage and pkTopk.
shots, the number of cycles of the waveform to be produced after a trigger event. If
non-zero (from 1 to MAX_SWEEPS_SHOTS), then sweeps must be zero.
sweeps, the number of times to sweep the frequency after a trigger event,
according to sweepType. If non-zero (from 1 to MAX_SWEEPS_SHOTS), then
shots must be zero.
triggerType, the type of trigger that will be applied to the signal generator:
PS6000_SIGGEN_RISING
trigger on rising edge
PS6000_SIGGEN_FALLING
trigger on falling edge
PS6000_SIGGEN_GATE_HIGH
run while trigger is high
PS6000_SIGGEN_GATE_LOW
run while trigger is low
triggerSource, the source that will trigger the signal generator:
PS6000_SIGGEN_NONE
run without waiting for trigger
PS6000_SIGGEN_SCOPE_TRIG
use scope trigger
PS6000_SIGGEN_AUX_IN
use AUX input
PS6000_SIGGEN_SOFT_TRIG
wait for software trigger provided by
ps6000SigGenSoftwareControl
PS6000_SIGGEN_TRIGGER_RAW
reserved
If a trigger source other than P6000_SIGGEN_NONE is specified, then either
shots or sweeps, but not both, must be non-zero.
extInThreshold, not used.
