器。 Consists of a plurality of output terminals, a switch for obtaining multiple outputs for the output terminal, a wattmeter for output level monitoring, an attenuator for level adjustment, and a control device for controlling these switchers, wattmeter, and attenuator. , the control device retains errors in attenuation due to differences in frequency characteristics and transmission system lengths to the switching device and output terminal as correction data, monitors the output level based on the correction data, and monitors the output level by the attenuator. A communication device characterized in that the amount of attenuation is varied and set to a corrected value, and after setting the amount of attenuation, the switch is operated to output a signal from one of the output terminals. Multi-output signal generator for measurements.
