H1 SUS ZM2 Electronically Functional (using OM1 signal Chain), and Mechanically Free
J. Kissel, B. Weaver, S. Pant

After yesterday's connection of ZM2 to the single functional 4-OSEM electronics chain in HAM5/6 --> readout as "OM1", and re-arranging the control setup (i.e. changing the OSEM2EUL and EUL2OSEM matrices) from an OFIS to an HTTS, we were able to grab the first transfer functions functions of the brand-new HTTS in HAM5 -- ZM2. The results look excellent. The suspension is free, resonances look quite similar (read: close enough) to a previous reference of OM1, and the DC scale looks right-on target. Nice!!

I attached screen-shots of the results.

We'll wait for chamber close-out to really make these TFs official with the full matlab analysis suite, but for now, the new data (again, still using channels that claim "OM1" as the suspension) live here:

        2017-11-30_1724_H1SUSZM2_M1_WhiteNoise_Y_0p01to50Hz.xml

(Note that, in committing these to the SVN, I've created two new corners of the SVN to make space for ZM1 and ZM2).
