Table B 6: Low level output voltage accuracy
Settings
Low voltage level (V) High voltage level (V)
-1.50 +3.50
0 +3.50
+1.00 +3.50
+2.00 +3.50
+3.25 +3.50
The following steps check the clock output amplitude accuracy.
6. Disconnect the BNC cable from both the digital multi–meter input and the
DG2030. And then connect the clock output to the oscilloscope CH1 input
as shown in Figure B-12.
7. Load the TP8PULSE.PDA test pattern file from the performance check
disk.
8. Using the oscilloscope measurement functions, perform the measurements
under the low and high voltage level settings shown in Table B-7, and
confirm that the amplitude for each voltage setting is within the specified
range.
