Procedure. Follow the steps below to verify pattern data output:
1. Load the TP2PG.PDA test pattern file from the performance check disk.
2. Press the START/STOP button on the front panel. The LED, corresponding
to the button, should be on.
3. Verify that the data pattern shown in Figure B-5 appears on the oscilloscope.
4. Disconnect the SMA cable from the CH0 output connector and the CH0
output connector on the DG2040 Data Generator , and then connect them to
the CH1 output connector and the CH1 output connector on the DG2040
Data Generator.
5. Verify that the pattern data shown in Figure B-5 appears on the oscilloscope.
6. Disconnect the BNC cable from event input connector on the DG2040 Data
Generator rear panel.
7. Change the oscilloscope acquisition sequence to Single Acquisition
Sequence.
