AC-Coupled Low Frequency Test
1.
Connect the test setup as shown in the previous test. (See Figure 3 on page 6.)
2.
Set all channels on the oscilloscope to:
Coupling: AC
Probe Type: Voltage, Attenuation: 1:1
Input Options: Polarity: Normal, Bandwidth: 20 MHz
Measure: Measurement on, V ac
Acquire Options: Glitch: Off, Memory: Short, Average: Off, Waveform: Normal
Ground level centered vertically
Horizontal scale: 40 ms/div
3.
Set the oscilloscope to display Channel 1.
4.
Set the oscilloscope vertical sensitivity to 500 mV/div.
5.
Set the calibration generator to 900 mV, 60 Hz.
6.
Enable the calibration generator output.
7.
Verify that the measured output voltage on the oscilloscope is 873 mV to 927 mV.
8.
Set the calibration generator to 900 mV, 5 Hz.
9.
Verify that the measured output voltage on the oscilloscope is >630 mV.
10.
Repeat steps 3 through 9 for the remaining channels on the oscilloscope. Trigger on the appropriate channel as needed.
11.
Set the generator output to 0 V and to standby.
