|
7
Complete the following steps to adjust the digital clock manager (DCM) of the NI 5105.
1.
Obtain an instrument session handle using the niScope Cal Start VI.
Note
Throughout the procedure, refer to the C/C++ function call parameters for the
LabVIEW input values.
2.
Connect the calibrator test head directly to the PFI 1 input of the device. Configure the
calibrator to output a sine wave with 3.0 V
pk-pk
amplitude, 50
Ω
load impedance, and the
Input Frequency
listed in Table 4 for the current iteration.
3.
Wait 2,500 ms for the impedance matching and frequency of the calibrator to settle.
4.
Adjust the digital clock manager (DCM) using the niScope Cal Adjust DCM VI.
5.
Repeat steps 2 through 4 for each iteration listed in Table 4.
LabVIEW VI
C/C++ Function Call
Call
niSCope_CalStart
with the
following parameters:
resourceName
: The name of the device
to calibrate. You can find this name under
Devices and Interfaces in MAX
