Abstract: A signal generator and a method for controlling the signal generator, capable of suppressing variation in the intensity of signals inputted to multiple devices under test are provided. An attenuation amount setting unit 15 sets a reference attenuation amount, obtained by subtracting the maximum amount of the losses stored in the cable loss storage unit 16 with respect to the cables 4a to 4f connected to the output ports 12a to 12f from a target attenuation amount, to the first attenuator 11, and sets an output attenuation amount, obtained by subtracting the losses stored in the cable loss storage unit 16 with respect to each of the cables 4a to 4f connected to the output ports 12a to 12f, from the maximum amount of the losses, to each of the second attenuators 14a to 14f.

Abstract: There is provided an attenuation amount setting unit that sets, in a case where signals are simultaneously output from all output ports of a plurality of interface units at the same signal level, one of the plurality of interface units as the reference interface unit, and adds a difference between an attenuation amount of a second attenuator stored in a storage unit of the reference interface unit and an attenuation amount of another second attenuator stored in another storage unit of the other interface unit to an attenuation amount of each of a plurality of third attenuators of the other interface unit to correct the attenuation amount.

Abstract: There is provided an attenuation amount setting unit 19 that sets, in a case where signals are simultaneously output from all output ports 17a, 17b, and 17c of a plurality of interface units 12a and 12b at the same signal level, one of the plurality of interface units 12a and 12b as the reference interface unit 12a, and adds a difference between an attenuation amount of a second attenuator 14 stored in a storage unit 18 of the reference interface unit 12a and an attenuation amount of another second attenuator 14 stored in another storage unit 18 of the other interface unit 12b to an attenuation amount of each of a plurality of third attenuators 15a, 15b, and 15c of the other interface unit 12b to correct the attenuation amount.

Abstract: To provide a signal processing device which enable the user to rapidly repeat an operation of changing to a different resolution with a fingertip touch in the line of sight to a displayed graph. A display unit 31 that displays a graph, a touch panel 32 that is provided so as to correspond to a display screen 31a and includes a touch sensor for outputting positional information associated with a touch operation, and a parameter data table 44 that stores a plurality of processing parameters corresponding to each positional information item. A control unit 50 includes a processing parameter output unit 54 that reads the processing parameter corresponding to the positional information from the parameter data table 44 and outputs the processing parameter to the processing parameter setting unit 21, if the positional information is input.
