Resume of collected problems

We experienced a number of problems both sampling the optical IF and collecting FF data. such problems seem to be related to the modes definition (see previous log for optical results, and through the following for the electrical)

While collecting ff data, both zonal and modal, the last 3 modes were not applied. This was verified

Activity

FF_MATRIX acquisition: 1 iteration, modal, 650 working acts: tracknum = 20110311_102733

the last 3 modes are empty (

Marco found that the SWITCH_MAP.ENABLEACCCORRECTION bit set to 2: this corresponds to clearing up the reconstructor gain for the last 3 modes (see doc. 641A006E_ElectronicDesign_ext.doc) -----> modes applied are empty

A check was inserted in ff_acquire_v2, to verify that the bit is set to 0 (modes are not affected in any way)

New acquisition of FF_MATRIX: 650 modes, zonal: tracknum= 20110311_105554. the last 3 modes are not empty. the problem seems to be fixed

New acquisition of FF_MATRIX: 650 modes, 5 iterations, modal, tracknum= 20110311_111051. no residuals on act 147

This new FF_MATRIX is now used as system FF (stored in configuration).

New acquisition of FF_MATRIX (with new ff linked), for verification: 1 iteration, modal, tracknum= 20110311_120059.

New acquisition of FF_MATRIX, with new Accelerometers software re-enabled: tracknum= 20110311_123655: no missing modes ---> acc software is not a problem

Calibration

New acquisition of FF_MATRIX: 650 modes, modal, 20 iterations: tracknum= 20110311_130523

New OptIntMat:
