N&DLY Test. To enter this test, press 6 while in the Diagnostics menu. This test verifies that the N and DELAY counter
will run continuously. Refer to the Diagnostics menu or to the trouble-shooting tree in
for details. Figure 3-15
illustrates the N&DLY test.
operation: Set the counter values in the N and DELAY fields. (Default: N = 1; DELAY = 0.) Press START to begin the
test. This is not a verification test, so you should probe the LOAD N signal or the LOAD DL signal with an
oscilloscope to verify these counters. To exit this test, press STOP and then press X.
NOTE
In the case of N = O (or DLY = 0), the N counter (or the DELAY counter) will not run
at all. This status is correct.
SEQ Test. To enter this test, press 7 while in the Diagnostics menu. This is an overall test for parallel acquisition
components. Refer to the Diagnostics menu or to the trouble-shooting tree in
for details. Figure 3-16 illustrates
the SEQ test.
operation: Press START to begin test. The LOOP test and DISP ON/OFF functions are available here. The LOOP test
has four features: OFF, I/O, ERROR, and TEST. These can be selected by pressing SELECT even during
testing. DISP can also be selected during testing. If DISP is OFF, no results will appear on the screen other
than results of the I/O LOOP test. To exit this test, wait until the test finishes, or press STOP, and then press
X. If errors are detected and DISP is ON, some of the following error codes will appear on the screen.
Error codes: 50, 51, 52, 53 (Refer to
Figure 3-15. Display for N counter or DLY counter tests.
