Dual Arbitrary Waveform Generator Check
This check verifies the functionality of the dual arbitrary waveform generator. A triangular waveform is
downloaded into the signal generator and then output to the rear-panel I and Q outputs. An oscilloscope is
used to monitor the rear-panel I and Q outputs.
NOTE This is not a performance test. This check is only provided to ensure that the dual arbitrary
waveform generator is operational. The results are verified visually on the oscilloscope, and
there is no data that is automatically logged or that can be printed out.
Recommended Equipment
• An oscilloscope with 2 input channels (for example, an Agilent 54610B digital oscilloscope)
Equipment Setup
Figure 3-35 Dual Arbitrary Waveform Generator Check Setup
Procedure
1. Connect the test equipment as shown. The oscilloscope is not connected to GPIB; this allows for the use of
most general 2-channel oscilloscopes.
2. Set the oscilloscope to display both Channel 1 and Channel 2. Set the oscilloscope to trigger on Channel 1.
The recommended settings are:
• Vertical Scale: 500 mV/div
• Timebase: 5 microseconds/div
3. Verify that Channel 1 and Channel 2 are both displaying triangular waveforms approximately 180 degrees
