Abstract
The invention concerns a method for generating calibration signals for calibrating spatially remote signal branches of antenna systems. In accordance with the invention, a base signal is generated by mean of a timer and is fed to a distributor unit for distribution of the base signal to amplifier circuits on the signal distribution lines respectively allocated to them. At the output of the amplifier circuits, a calibration signal is generated respectively via amplification of the base signal within a specifiable upper amplitude limit and a specifiable lower amplitude limit, which is fed to the respective feed-in point of the signal branch to be calibrated that is allocated to an amplifier circuit.
Claims15
A method for generating calibrating signals for calibrating receiving and transmit paths of antenna systems, whereby the receiving and transmit paths are remotely located from calibrating measuring devices comprising:
- generating a base signal by means of an arrangement for signal generation comprising a timer, a J/K-flip-flop, and a multiple alternation switch;
- feeding said base signal to a distributor unit, said distributor unit distributing said base signal to amplifier circuits on signal distribution lines respectively allocated to said amplifier circuits;
- generating said calibration signals at outputs of said amplifier circuits by amplifying said base signal within a specifiable upper amplitude limit and a specifiable lower amplitude limit;
- and
- feeding said calibration signals to the respective feed-in points of said signal receiving and transmit paths allocated to said amplifier circuits.
