NI 5450 Calibration Procedure
60
ni.com
Complete the following steps to externally adjust the NI 5152/5153/5154.
1.
Obtain a calibration session handle using the niScope Cal Start VI.
2.
Connect the calibrator test head directly to the digitizer input
channel 0.
3.
Configure the calibrator to output the voltage listed under
Input (V)
in Table 17 (NI 5152), or Table 18 (NI 5153/5154) for the current
iteration. Configure the load impedance of the calibrator to 1 M
Ω
(NI 5152), or 50
Ω
(NI 5153/5154).
4.
Wait 2,500 ms for the impedance matching of the calibrator to settle.
5.
Adjust the vertical range using the niScope Cal Adjust Range VI.
6.
Repeat steps 3 through 5 for each iteration in Table 18 (NI 5152) or
Table 19 (NI 5153/5154).
7.
Move the scope calibrator test head to the digitizer input channel 1 and
repeat steps 3 through 6, changing the value of the
channelName
parameter from
"0"
to
"1"
.
8.
Move the scope calibrator test head to the external trigger channel
input on the digitizer.
