Time Base Test
1.
Connect the test setup as shown. (See Figure 5.)
Figure 5: Time base test setup
2.
Set the generator to source a 8 ms time marker (MODE marker).
3.
Reset the oscilloscope: Power off, press and hold Utility, power on, wait for double beep then release Utility button.
4.
Set Channel 1 on the oscilloscope to:
Coupling: AC
Probe Type: Voltage, Attenuation: 1:1
Input Options: Polarity: Normal, Bandwidth: 20 MHz
Acquire Options: Glitch: Off, Memory: Short, Average: Off, Waveform: Normal
Vertical sensitivity to 500 mV/div
Ground level centered vertically
Horizontal scale: 10 ms/div
5.
Position the trace to the left until the trigger delay time is indicated in the bottom-right corner of the display. Adjust the
trigger delay time to 8.00 ms. This value represents the delay time with respect to the
fi
rst vertical grid line.
6.
Set the time base to 10
μ
s/div.
7.
Position the trace to the right until the indicated trigger delay is 7.990 ms. (See Figure 6 on page 14.)
