NOTE. The pulse rise time tests use the AWG710 Arbitrary Waveform Generator
s control settings that have been used in the amplitude and DC offset tests. Do
not initialize the AWG710 Arbitrary Waveform Generator controls.
3. Load the PULSE.WFM file.
Refer to Loading Files on page 4–10 for file loading procedures.
4. Push SETUP (front-panel)!Run Mode (bottom)!Continuous (side).
The AWG710 Arbitrary Waveform Generator is set to the Continuous mode.
5. Change the AWG710 Arbitrary Waveform Generator controls as follows:
a. Push VERTICAL MENU (bottom)!Amplitude (side).
b. Push 1 and ENTER keys in this order or turn the general pur-
pose knob to set the amplitude to 1 V.
6. Push the RUN and CH1 output buttons.
The LEDs above the RUN button and CH1 output connectors are on.
7. Verify that the rise time of the pulse waveform displayed on the oscilloscope
is equal to or less than 175 ps.
8. Do the following substeps to change the connection to check the CH1
:
a. Push the CH1 output button.
b. Disconnect the cable from the CH1 output connector.
c. Connect the cable to the CH1
output connector.
d. Push the CH1
output button to turn on the CH1 LED.
9. Repeat step 7 to verify the rise time for the AWG710 Arbitrary Waveform
Generator CH1
.
10. Push the CH1
output button to turn off the CH1 LED.
