Tests for TDC full Crate Test
			25-Nov-1998

For each of the following tests want to measure slope and T0.  In addition 
look at RMS from pulsing at a specific pulse delay.  

1. One TDC vs many TDCs: compare performance of a single TDC in crate with 
performance of same TDC when pulsing many TDCs in crate.  Try this with 
several different TDCs.  Try this with TRACER at end of crate and in middle of 
crate to see if our clock problems affect the calibration.

2. With all TDCs: performance of TDCs as a function of power supply voltage
try 4.9, 5.0, 5.2V.  The crate may not work at 4.9V, I have had problems with 
this before.

3. With all TDCs: Time/temp stability.  Performance as a function of time 
after turning on crate (eg every 10 minutes for 1 hour).  Turn crate off and 
on and repeat.

4. With all TDCs: Long term running stability.  Run for several days 
continuously.  Look at:
	Stability of slopes and RMS
	Number of readout errors etc	

5. Stability of TRACER calibration signal.  Analyze above data for for 
stability of difference between TDCs and channels on a single TDC.  Are any 
variations coherent or incoherent?

6. Effect on power supply stability: while pulsing and reading out all TDCs 
look at power supply voltage on scope.  Compare to quiescent state.

7. Measure readout speed with MVME2301

8. Connect to VRB and test full readout.  
   a) Test TRACER SPY mode operation
   b) Measure link error rate (how?)
   c) Readout timing
