To configure the counter to work in this mode, set JY5211CITask.Mode to
CIMode.Finite or CIMode.Continuous
,
and set JY5211CITask.SampleClock.Source to
CISampleClockSource.Implicit.
Timebase
By default, the counter uses the onboard 200MHz timebase to measure pulses. Use
the property JY5211CITask.TwoEdgeSeparation.Timebase to configure the timebase.
Please refer to chapter 4.5.3 for more information about timebase.
Terminals
To change the terminal of signals instead of using its default value shown in chapter
2.6, using following properties:
JY5211CITask.TwoEdgeSeparation.FirstInputTerminal – First signal-to-measure
input terminal.
JY5211CITask.TwoEdgeSeparation.SecondInputTerminal
–
First
signal-to-measure input terminal.
JY5211CITask.TwoEdgeSeparation.Timebase.External.Terminal
–
External
timebase input terminal.
Learn by Examples 4.3.5
Connect the signal source’s two positive terminals Ch1, Ch2 to PCIe/PXle-5211
first signal input (Gate, Pin#31) and second signal input (AUX, Pin#63), two
negative terminals to the ground (GND, Pin#64) and (GND, Pin#28).
Set the signal source Ch1’s to squarewave signal (f=20Hz, Phase=0
°
), Ch2’s
output to squarewave signal (f=20Hz, Phase=90
°
).
Single Mode
Open
Counter Input-->Winform CI Single Two-Edge Separation
and click
Start
.
The result is shown below by
First Separation
and
Second Separation
, which
represent the number of rising edges on the timebase difference between the
rising edges of the two signals:
