A method and apparatus for testing mobile communication devices involve utilizing the device's frequency hopping capabilities to substantially reduce the time required to measure operational parameters of the device at a plurality of frequencies across the device's operational frequency band. Prior to conducting the multi-frequency test, a device tester defines a hopping list of test frequency channels and transmits the hopping list and command signals to the mobile communication device for testing a set of operational parameters of the device at all of the test frequencies. The mobile communication device then measures all of the parameters at all of the frequencies by repeatedly sequentially hopping through the test frequencies in accordance with the hopping list. Since the period between frequency hops is shorter than the time required to complete measurement of a parameter at a particular frequency, each parameter measurement at each test frequency is obtained by combining measurement results of plural bursts at each test frequency. The process eliminates the time-consuming need to transmit control signals between the tester and device prior to conducting parameter tests at each frequency. By rapidly hopping among test frequencies across the frequency band, the effect of making operational adjustments to the mobile communication device while under test can be observed in real time across the frequency band, thereby simplifying the adjustment process.
