4.1 PERFORMANCE ANALYZER (GYRO SETUP PROGRAM)

The Gyro Setup program is organized as a main window with several tabs to individual functions. The

application is organized into the following tabs.

1. CAL / STATUS

2. NOTCH FILTERS

3. SCOPE

4. SPECTRUM ANALYZER

5. BODE PLOT

6. LOADER

To begin, the user should select the CAL / STATUS tab and request a status report command. After doing

so, the GCU should reply with the current software revisions for the individual programmable devices. The

user should then request the GCU to report back the current control loop parameters by selecting the “Read

Gyro Contents” command button. At this point, the Calibration Coefficients for the GCU unit are filled in

for inspections. Most values can be modified and sent to the GCU module. If the user desires to save these

values in the GCU flash memory they can select the “Save Calibration” command.
