Verification Test (continued)
DC Offset Accuracy
1. Set AMPL (Amplitude) to 1.00 V.
2. Select STDW (Standard Wave) as SIN (Sinewave) (1000 points).
3. Connect OUTPUT to DMM input without the terminating load.
4. Set
OFST (DC offset) to 9.000 V.
5. Set DMM to DC measurement and verify that DC offset measures between 8.890 V and 9.110 V.
6. Set
AMPL (Amplitude) to 100 mV.
7. Set OFST (DC offset) to 899 mV.
8. Verify that DC offset measures between 867 mV and 931 mV.
9. Set
AMPL (Amplitude) to 10 mV.
10. Set OFST (DC offset) to 89 mV.
11. Verify that the DC offset measures between 83.5 mV and 94.5 mV.
Amplitude Accuracy
1. Select STDW (Standard Wave) as SIN (Sinewave) (1000 points).
2. Set FREQ (Frequency) to 1.000 kHz.
3. Connect OUTPUT to DMM without terminating load.
4. Set
AMPL (Amplitude) to 10.20 V.
5. Measure true-RMS amplitude on DMM and convert the data to peak value by multiplying by 1.414.
6. Verify the peak value is between 10.078 V and 10.322 V.
7. Set
AMPL (Amplitude) to 900 mV.
8. Measure true-RMS amplitude on DMM and convert the data to peak value by multiplying by 1.414.
9. Verify the peak value is between 868 mV and 932 mV.
10. Set
AMPL (Amplitude) to 90 mV.
11. Measure true-RMS amplitude on DMM and convert the data to peak value by multiplying by 1.414.
12. Verify the peak value is between 84.5 mV and 95.5 mV.
Total Harmonic Distortion (THD) plus Noise
1. Select STDW (Standard Wave) as SIN (Sinewave).
2. Set AMPL (Amplitude) to 9.10 V.
3. Select 700K (700 kHz low pass filter) from OUTPUT menu.
4. Set FREQ (Frequency) to 2.000 kHz.
5. Connect OUTPUT to the distortion analyzer input using a 50 0 load.
6. Set the distortion analyzer for a 2 kHz signal and 80 kHz measurement bandwidth.
7. Verify THD+Noise measures less than -86 dB (0.005%).
