5.28 ps2000SetPulseWidthQualifier
int16_t ps2000SetPulseWidthQualifier
(
int16_t handle,
PS2000_PWQ_CONDITIONS *conditions,
int16_t nConditions,
PS2000_THRESHOLD_DIRECTION direction,
uint32_t lower,
uint32_t upper,
PS2000_PULSE_WIDTH_TYPE type
)
This function sets up pulse width qualification, which can be used on its own for pulse width
triggering or combined with other triggering to produce more complex triggers. The pulse
width qualifier is set by defining a conditions structure.
Applicability
Available in block mode and fast streaming mode only
PicoScope 2202, 2204, 2204A, 2205 and 2205A only
Arguments
handle: the handle of the required oscilloscope
conditions: a pointer to a PS2000_PWQ_CONDITIONS structure
specifying the conditions that should be applied to the trigger channel. If
conditions is NULL then the pulse width qualifier is not used.
nConditions: should be set to 1 if conditions is non-null, otherwise 0
direction: the direction of the signal required to trigger the pulse
lower: the lower limit of the pulse width counter
upper: the upper limit of the pulse width counter. This parameter is used
only when the type is set to PW_TYPE_IN_RANGE or
PW_TYPE_OUT_OF_RANGE.
type: the pulse width type, one of these constants:
PW_TYPE_NONE
do not use the pulse width qualifier
PW_TYPE_LESS_THAN
pulse width less than lower
PW_TYPE_GREATER_THAN
pulse width greater than lower
PW_TYPE_IN_RANGE
pulse width between lower and upper
PW_TYPE_OUT_OF_RANGE
pulse width not between lower and upper
Returns
0: if unsuccessful, or if one or more of the arguments are out of range
non-zero: if successful
