Added a synchronized oscillator to L3 stage in QUAD_MASTER (SUS-ETMY recompilation pending)

Overview

A synchronized oscillator was added to QUAD_MASTER model test mass stage (L3). After re-compiling the SUS-ETMY model there will be two synchronized ossilators in L3 stage that will be used for driving calibration lines: *_L3_CAL_LINE and *_L3_CAL2_LINE.

Removed channel LKIN_P_LO from the list of DQ channels and added L3_CAL2_LINE_OUT into the list.

The h1susetmy model must be recompiled in order for the changes to take effect.

Details

For one of the two calibration lines that we needed to run during ER9 we used a pitch dither oscillator, SUS-ETMY_LKIN_P (see LHO alog 28164). After analyzing the ER9 data we found two problems with this line (see LHO alog 29108):

The second synchronized oscillator was added at L3_CAL2_LINE_OUT and the list of DQ channels was modified accordingly. The L3_CAL2_LINE_OUT was added with sampling rate 512 Hz. LKIN_P_LO was removed from the list of DQ channels.

The changes were commited to USERAPPS repository, rev. 14081.

Dave, TJ, Jeff K, Darkhan,

H1:SUS-ETM(X|Y) were recompiled and restarted, DAQ was restarted (see LHO alog 29245, WP 6117).

The QUAD MEDM screen was updated to show the new oscillator settings.

The MEDM screen updates were committed to userapps repository (rev. 14088):
