10. Configure the horizontal properties using the niScope Configure Horizontal Timing VI.
11. Repeat steps 11a through 11e for each
Input Frequency
listed for the current iteration in
Table 12 (NI 5122/5142) or Table 13 (NI 5124).
a.
Configure the calibrator to output the
Input Frequency
for the current iteration in
Table 12 (NI 5122/5142) or Table 13 (NI 5124).
b.
Wait 2,500 ms for the impedance matching and frequency of the calibrator to settle.
c.
Initiate a waveform acquisition using the niScope Initiate Acquisition VI.
