Fluke 9000A-Z80QT, Instruction Manual

Page: 54 / 108

ZSOQT
An
8
MHz
clock signal is appliedto the clock input of the pod. This clock
signal replaces the clock normally supplied by the UUT to operate the
pod.
All
forcing
lines and
interrupts
are set to the active state. Setting these
lines allows testing of the individual hardware
or software buffering.
+5V dc is applied
to pin
11
to simulate UUT power and check the power
fail sensing circuit.
Ground
is applied through
the
ribbon
cable to
pin
29 to
notify the
mainframe that
the pod is
in the self test configuration.
To perform self test with a 9000 Series, proceed
as
follows:
1.
If not alreadyconnected,connect the interface pod to the mainframe
as shown in Figure 2-1.
Secure the connector
using the sliding collar.
2. Open the pins of the self test socket
by
operating the adjacent
thumbwheel. Insert the
ribbon
cable plug
into
the socket and close the
socket using the thumbwheel.
3.
Turn the
mainframe
on and press BUS TEST to initiate self test.
4.
If the mainframe
and pod are operating
normally, the mainframe
display reads
POD SELF-TEST
Z80QT OK.
5.
If the pod
is
defective
but not
completely dead, the mainframe
displays
POD SELF-TEST
Z80QT
FAIL
xx, where xx represents the
pod
fault
listed in Table
5-1.
Refer to the troubleshooting procedures to
further
isolate the problem.
6.
If
the pod
is
inoperative, the mainframe reads
POD TIMEOUT
-ATTEMPTING
RESET. This message indicates
that
the pod is
not
responding to
commands issued by the mainframe. Refer to the
troubleshooting
procedures to isolate the problem.
To perform
self test with a 9100 Series, proceed
as
follows:
1.
If not alreadyconnected,connectthe
interface pod to the mainframe
as
shown in Figure
2-2,
Secure the connector
using the sliding collar.
