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.
