8. Using ArbConnection, build and download the following
sequence table:
Step 1: Segment 1, loop 1
Step 2: Segment 2, loop 1
Step 3: Segment 3, loop 1
Step 4: Segment 4, loop 1
Step 5: Segment 5, loop 1
Test Procedure:
1. From ArbConnection, click on the Manual Trigger and
observe that the waveforms advance through the sequence
table repeatedly
Test Results Pass Fail
Note
Leave the same setup for the next test
Single Advance Equipment: Oscilloscope, function generator
Preparation: (Same preparation as for previous step, except change
mode to single sequence advance)
1. Change Oscilloscope configuration to single
Test Procedure:
1. From ArbConnection, click on the Manual Trigger observe
that one cycle waveform advances through the sequence
table repeatedly with each external trigger signal. Note that
you need to press the Single mode on the oscilloscope for
each trigger advance
Test Results Pass Fail
SYNC Output
Operation
This tests the operation of the SYNC output. There are two
synchronous output are being tested – Bit and LCOM. Bit normally
operates with standard and arbitrary waveforms and LCOM is always
associated with sequenced and burst outputs. The sync output has
fixed TTL level amplitude into an open circuit.
