Vertical Accuracy Test
WARNING.
Dangerous voltages will be present on the calibration generator output terminals and connection cables. Always
verify that the generator is in the standby mode before you make any connections to the generator.
1.
Connect the test setup as shown. (See Figure 2.)
Figure 2: Setup for vertical accuracy test
2.
Press the Ch 1 button once (for channel 1). The menu that appears on the bottom of the screen allows you to change
settings. Set all channels on the oscilloscope to the settings below:
Probe Type: Voltage, Attenuation: 1:1
Input Options: Polarity: Normal, Bandwidth: 20 kHz (HF Reject)
Measure: Measurement on, V dc
Acquire Options: Glitch: Off, Memory: Short, Average: Off, Waveform: Normal
Ground level centered vertically
Horizontal scale: 10 ms/div
3.
Set the oscilloscope to display Channel 1.
4.
Set the oscilloscope vertical sensitivity to the
fi
rst value in the table. (See Table 2.)
5.
Set the calibration generator to the
fi
rst value in the table.
6.
Enable the generator output and adjust the generator output voltage until the displayed trace amplitude is 6 divisions.
7.
Verify that the generator output voltage is within the range shown under the appropriate column.
8.
Continue through the test values remaining in the table for Channel 1.
9.
Disable the generator output and move the output cable to the next oscilloscope channel.
10.
Repeat steps 3 through 9 for the remaining channels on the oscilloscope.
