[evlatests] ea23 3-bit working fine

[Michael Rupen]

p.s. The module serial number for ea23 is
   ea23-d301  085 111003|1323
   ea23-d303   99 111004|0812

> The 3-bit sampler which used to be on ea12 was moved to ea23 yesterday.
> A quick look at X-band this morning shows nice fringes and reasonable power
> levels on all 3-bit IFs (ea23-A1,C1, A2, C2).
>
> The state count histograms for all samplers now on ea23 roughly match those 
> seen when
> the samplers were on ea12.  In particular, the C1 sampler still shows the 
> largest
> offset of any currently on the array (1.75 bins!).
>
> More detailed testing is on-going.
