b. Select waveform file:
H Push SETUP!Waveform Sequence, if necessary, to select a
waveform file for CH1. Waveform Sequence toggles between the
CH1 files (upper list) and the CH2 files (lower list).
H Turn the general purpose knob to highlight the CNTRL.WFM
file.
H Push ENTER to select the file.
3. Check rear panel CONTROL SIG OUT amplitude:
a. Check CONTROL SIG OUT pulse amplitude:
H Push Mode!Gated.
H Push the AWG2005 MANUAL TRIGGER button.
H Check that the pulse upper level of the displayed waveform is
2 V or greater.
H Check that the pulse lower level of the displayed waveform is
0.8 V or less.
4. End procedure: Disconnect the oscilloscope.
This procedure checks the external trigger level accuracy of the AWG2005.
Electrical Characteristic Checked:
on page 1 15.
Equipment Required:
an oscilloscope.
Prerequisites:
The AWG2005 meets the prerequisites listed on page 4 7.
Procedure:
1. Install test hookup and set test equipment controls:
a. Hook up oscilloscope: Connect the AWG2005 CH1 output through a
coaxial cable to the oscilloscope CH1 vertical input.
b. Hook up function generator: Connect the AWG2005 TRIGGER INPUT
through a coaxial cable to the function generator output (see Fig
ure 4 18).
