We found that the DARM_CTRL excitation line reverted to old values on 7/31 (last Friday) at about 11:13 PDT, 18:13 UTC. Perhaps this was the result of an errant BURT restore, but we didn't find a record of one in a quick survey of the aLog.
When we set the lines last week (see this link), we didn't update the SDF (our bad!).
Today, we reset the frequency of the DARM_CTRL line and adjusted the amplitude to give us SNR ~100. We also adjusted the amplitude of the Pcal lines to adjust their SNRs to be near the design values.
The updated settings are:
| Excitation point | Freq.(Hz) | Amp.(cts.) |
Target SNR (10-sec. FFT) |
Range used.(%) |
| DARM_CTRL | 37.3 | 0.085 | 100 | ?? |
| PcalY | 36.7 | 125 | 100 | 0.3 |
| PcalY | 331.9 | 2900 | 100 | 6.9 |
| PcalY | 1083.7 | 15000 | 13 | 36 |
