4.16 Calibration of Analog Housekeeping Data

Source: R. Gold
Date: Sept. 5, 1985

The analog housekeeping data for LAN are digitized by the spacecraft with an 8-bit A/D converter over the range from 0 to 5.10 volts. Thus the digitized values represent .020 volts per count. The calibration data for the Flight Model are contained in the table below and on the enclosed graph (Figure 4.92).
