Wavetek 75 - Communication Option 001 Troubleshooting; IEEE-488 Sample Check out Program

Table 6-27. Communication Option 001 Troubleshooting
Non-responsive, in whole or
in part.
Fault
Cycle power and reset
instrument. U2-3, -5, -7
thru -1 4, -37,
-38, -39.
U2-6.
U2-4, -1 6,
-1 7, -1 8, -21,
-22, -23, -25,
-26, -27, -29
thru -36, -40.
Setup
No stuck bits.
1 MHz.
All high.
Check
Connect instrument to
IEEE-488 controller. Set
controller in loop that
"talks to'' and "reads
from" the Model 75. As
part of loop, generate a
programming error
(A1 01) and then serial
poll the unit.
NOTE: Figure 6-6 shows
a sample program
written on a Wavetek
Model 6000.
Results Desired
U2-21 and
-29.
U2-22.
U2-40, U3-1
thru -9, -1 2
thru -19,
U4-1 thru -9,
-1 2 thru -1 7.
Logic levels
on bus side
of U3 and
U4.
Both high.
A low.
No stuck bits.
