1. An error rate measurement apparatus that measures an error rate of an input signal from a device under test for a measurement time, the error rate measurement apparatus comprising:
a display unit that displays a setting screen for setting a measurement condition of the error rate; and
a processing unit that calculates the measurement time prior to measurement of the input signal,
wherein the setting screen includes:
a target confidence level input portion for inputting a target confidence level,
a transmission rate input portion for inputting a transmission rate of the input signal,
a target error rate input portion for inputting a target error rate of the input signal,
an assumed number of errors input portion for inputting an assumed number of errors during the measurement time of the input signal, and
a measurement time display portion for displaying the measurement time of the input signal, and
the processing unit calculates the measurement time satisfying the target confidence level based on the target confidence level, the transmission rate, the target error rate, and the assumed number of errors, which are input to the setting screen.
