Adjustment Procedures
5-12 AWG510 & AWG520 Service Manual
This procedure adjusts variable delay setting on the A50 AWG board for
theDAC clock timing. See Figure 5–6 on page 5–11 for the adjustment location.
Equipment
Required One oscilloscope (Item 1)
One 50 coaxial cable (Item 5)
1. Connect the test equipment and set test equipment controls:
a. Connect the oscilloscope: Connect the AWG500 CH 1 output connector
through a BNC coaxial cable to the CH 1 input connector on the
oscilloscope.
