Functional Verification
The functional verification procedure consists of the following parts:
H
Self tests and power-on diagnostics
H
Extended diagnostics
H
Self calibration (Self cal)
H
Probe calibration
This procedure provides a functional check only. Perform the functional
verification procedure whenever you need to gain confidence that the DSO
module is operating properly. If more detailed testing is required, perform the
performance verification procedure, which begin on page 4--7, after completing
the functional check procedures.
You will need the following test equipment identified by the item numbers listed
in Table 4--1 on page 4--3.
H
TLA700 Series Logic Analyzer mainframe with one DSO module
H
One P6243 or P6245 oscilloscope probe, with standard accessories (item 3)
H
One DSO probe calibration fixture (item 2)
H
One male-male BNC adapter (item 4)
It is assumed that the DSO module is properly installed and that all accessories
are connected. Refer to the
Tektronix Logic Analyzer Family User Manual for
detailed installation instructions.
Power on the instrument and allow a 30-minute warmup before continuing with
any procedures in this section.
During power-on, the installed modules perform an internal self test to verify
basic functionality. No external test equipment is required. The self tests require
only a few seconds per module to complete. The front-panel ARM’D and
TRIG’D indicators blink during the self test. After testing completes, the front
panel indicators have the following states:
H
READY — Green (on)
H
ACCESSED — off
H
ARM’D — off
