Overshoot Test
Specification:
Signal Characteristic
Square
Overshoot
Typical (100kHz, 1Vpp)
≤5%
Test Procedures:
1. Make sure that the environment temperature is between 18℃ and 28℃ and
DG1000Z has been warmed up for at least 30 minutes. Connect the channel
output terminal (take CH1 as an example; the test method is also applicable to
CH2) of DG1000Z with the signal input terminal of the oscilloscope using a
dual-BNC connecting cable as shown in Figure 2-5.
2. Turn on DG1000Z. Press Utility Set To Default OK to restore DG1000Z
to factory setting.
3. Set DG1000Z:
a) Set the output impedance of CH1 to 50Ω (press Utility Channel Set
Output Set Imped and select “Load”).
b) Set the output waveform of CH1 to a square waveform with 100kHz
frequency, 1Vpp amplitude and 0V
DC
offset.
c) Press Output1 to turn on the output of CH1.
4. Turn on and set the oscilloscope:
a) Set the input impedance to 50Ω.
b) Set the vertical scale to 200mV/div.
c) Set the horizontal time base to 50ns.
d) Adjust the trigger level to a proper value.
e) Turn on the overshoot measurement function.
5. Record the overshoot measurement value and judge whether it is within the
specification range.
