· But currently there is not enough room for desk ..

2.Hardware(on hand):

·Crate Type A 10U CDF

·Power source( +12V,+5V, +3.3V,-12V )

·CPUMVME 162-532(B0svttest00)

·Oscilloscope (HP Infinium)

3.SVT spare modules (on hand):

·AMS - 1 (for test stand)

·Amboard- 5

·Amplug- 64

·Merger- 1 (for test stand)

·SPY- 4

·HB-1 (for test stand)

4.Status of test stand:

·Standard tests for AM systemworks.

(Am_test_vme, Am_test_data_loop, random tests)

·Investigation the reasons ofAM bugs during commissioning RUN in progress.

5.Real measurements the timing of AMBOARD:

àNo problemsatGLUE2, GLUE1 level

àCritical part- GLUE0!

But,relative positions for edges of signals CLKA, CLKB, CLK1, CLK3 can be improved!

See oscilloscope snapshot 1 and snapshot 2

6.Summary of testingfaulty Amplug fixed during commissioning RUN:

We have 34faulty amplug (from 592 amplug in total ):

à26 – small different timing ( no problem)

à6 – fatal errorsinside amchips (R/W opc – 4,

differentpatterns – 2)

à2 – timing too different

7.Questions/problems

Þ For SVT we are using Power PC Board MVME2304 and

for Test Stand we are going to use M162-537 Board.

The code is not always compatible….
