NI 5122/5124 Calibration Procedure
• inputImpedance: The Input Impedance value for the current
iteration from Table 3
• maxInputFrequency: The Maximum Input Frequency value for
the current iteration from Table 3
2. Call
niScope_ConfigureVertical
Vertical VI) with the following parameters:
• channelList:
• range: The Range value for the current iteration from Table 3
• offset:
0.0
• coupling:
NISCOPE_VAL_DC
• probeAttenuation:
• enabled:
NISCOPE_VAL_TRUE
3. Call
niScope_ConfigureHorizontalTiming
Horizontal Timing VI) with the following parameters:
• minSampleRate:
• minNumPts:
• refPosition:
• numRecords:
• enforceRealtime:
4. Call
niScope_Commit
parameter:
• vi: The instrument handle you obtained from
5. Short-circuit the channel 0 input of the digitizer by connecting the
calibrator test head directly to the digitizer and grounding the output of
the calibrator.
6. Wait 500 ms for the impedance matching of the calibrator to settle.
7. Call
niScope_InitiateAcquisition
Acquisition VI) with the following parameter:
• vi: The instrument handle you obtained from
8. Call
niScope_FetchMeasurement
Measurement VI) with the following parameters:
• channelList:
• timeout:
1.0
• scalarMeasFunction:
Compare the resulting average voltage to the value listed in the
Calibration Test Limits column or the Published Specifications column
in Table 4 (NI 5122) or Table 5 (NI 5124) that corresponds to the
vertical range used. The inputImpedance and maxInputFrequency
