SatDish 1.1   (details) 49/50 48 ENG   40KB/2KB
ScreenshotA program to determine the transmit gain, receive gain, and figure of merit (G/T) of a parabolic satellite communications antenna. It uses antenna diameter, efficiency, transmit frequency, receive frequency, and receive system noise temperature as inputs. Although developed for satellite communications, it should work with any parabolic antenna system.

SCpower - Power Network Short Circuit Program 5.0   (details) 48 ENG   251KB/12KB
ScreenshotThe SCpower program was written in an HP48G+; it also runs on the HP49G. It calculates three phase and one phase to ground (1LG) short circuit currents at faulted buses as well as fault currents that circulate through the power network. It uses 100 MVA as base power. It does not yet calculate LL or 2LG faults, nor does it take into account fault resistance. It creates and manipulates the positive and zero sequence impedance matrices of the power system.
