SLITEST: S-LINK Tester
(Circuit no. 680-1110-350)
DESCRIPTION
The
SLITEST is a board in VME form factor that can be used to test S-LINK
Link Cards. The card can be used on a desk top with a seperate 5 Volt
power supply. It can also be powered from a VME crate (only power is taken
from VME, there is no control over VME possible).
For testing Link Source Cards, the SLITEST
has to be used in conjunction with a SLIDAS, while
for testing Link Destination Cards a SLIDAD
is needed.
With the SLIDAS you can generate different datapatterns that are sent
at full speed into a Link Source Card. A Link Destination Card in combination
with a SLIDAD can be used to create an S-LINK data
sink.
Basically the SLITEST is made to use SLIDAS and a SLIDAD cards "upside
down". Normally those cards are used to test S-LINK Read-out Motherboards
or Front-end Motherboards. As the S-LINK protocol is rather symmetrical
on both sides of the link, the rather passive SLITEST board makes that
the SLIDAS and SLIDAD can be used to test links.
The SLITEST features:
-
Reset buttons for Link Cards and SLIDAD/SLIDAS
-
Buttons for selecting datawidth
-
Button for setting cards in test mode and receiving test data
-
Three seperate error counters
-
Errors in datablocks
-
Errors in data words
-
Errors in control words
-
Link Down status indicators
-
Phase Locked Loop for regenerating clock
