Testing of a frequency converter device

摘要

A user interface is presented for a tester that tests a frequency converter having an input port, an output port and a local oscillator port. In a first area, a user can specify frequency for an input signal to be placed on the input port. In a second area, the user can specify frequency for a local oscillator signal to be placed on the local oscillator port. The tester calculates expected frequency values of an output signal on the output port output based on values entered in the first area and the second area.
