Document Type and Number:
Japanese Patent JPS5523397
Kind Code:
B2
Abstract:
A spectrum analyzer is provided with a horizontal sweep generator that causes the analyzer to sweep at a fast rate when no signal is being detected. When a signal is detected the sweep generator stops sweeping, backs up and tunes the spectrum analyzer slowly through the detected signal to produce a calibrated display. After the signal has been detected and the analyzer has been tuned beyond it, the sweep rate is again increased until another signal is encountered.
