c. Select waveform file:
Push SETUP³Waveform Sequence, if necessary, to select a
H
waveform file for CH1. Waveform Sequence toggles between the
CH1 files (upper list) and the CH2 files (lower list).
Turn the general purpose knob to highlight the TRG_IN.WFM
H
file.
Push ENTER to select the file.
H
3. Turn on the AWG2005 CH1 output: Push the CH1 button so that the LED
above the CH1 output connector is on.
4. Check external trigger high level:
a. Adjust oscilloscope controls: Press and hold the AWG2005 MANU
AL TRIGGER button and adjust the oscilloscope vertical and hori
zontal position to display the waveform from the AWG2005. Release
the MANUAL TRIGGER button.
b. Enable function generator output: Turn on the function generator
output.
c. Check external trigger level accuracy:
Gradually increment the function generator offset level until a
H
waveform is displayed on the oscilloscope.
Check that that the function generator offset level is from 0.85 to
H
1.15 V when the waveform is first displayed.
5. Check external trigger low level.
a. Change the function generator controls:
Parameter
Offset
b. Change the AWG2005 controls:
Push MODE³Polarity to highlight Negative.
H
Select Level from the side menu, and turn the general purpose
H
knob to select -1 V. (You can also use the numeric and units
keys to select -1 V; then push ENTER.)
c. Check external trigger level accuracy:
Gradually decrease the function generator offset level until a
H
waveform is displayed on the oscilloscope.
Check that that the function generator offset level is from
H
-1.15 V to -0.85 V when the waveform is first displayed.
6. End procedure: Turn off the function generator output and disconnect
the function generator.
-0.6 V
