Jeff found out that the VXI has not been doing its self calibration during start up. Even when he changed the vxi setup file (hpvxi.setup, calibrate_option), it still didnt seem to do it. Therefore,to do it manually, bring up the menus in IDeas (ctrl+m) and find the perform calibration option.
I called Kaman and left a message about the capacitor in the frequency demodulator. I checked the broken capacitor, it is a 1.0uF, 35V capacitor.
I called Jeff Chang at measurement specialties about the status of our 4000A accels.
I worked on the rejection ratio test for Fast GVT. The gains for the circuit (2 in/sec/Volt) are set based on the calibration factors of the sensors. Thus if the sensor's cal is different, the circuit will not perform the same. In my case, both sensors are different than the ones used to tune the gains on the circuit. The cal on the disp sensor can be changed to account for this, however the cal on the accelerometer cannot.
Brad asked me to get John Harmon to organize the BNC cables from Yuma.
