Repeat 2 times, once for each channel.
1. Connect the AO channel under test to the DMM as shown in Figure 3.
Repeat 2 times, once for each output terminal configuration.
Repeat 4 times, once for each AO Attenuation.
Repeat 3 times, once for each frequency.
2. Configure the DMM using the information in Table 16.
3. Configure an AO Voltage channel task using the values in Table
21.
Table 21: AO Setup
Configuration Value
Physical Channels Dev_name/aox
AO Gain* Gain from Table 20
Output Terminal Configuration Configuration from Table 20
Rate 250000 S/s
Sample Mode Continuous Sample
Samples Per Channel 12500
*Refer to Table 17 for details about the correlation between AO Gain, DMM Range, and
Signal Amplitude.
4. Call DAQmx Channel Property Node, and set the AO Idle Output
Behavior property (Analog Output>>General Properties>>Output
Configuration>>Idle Output Behavior) to Zero Volts
5. Call Basic Function Generator Parameters using the parameters in
Table 22.
