Method and apparatus for testing mobile communication device employing frequency hopping

Communication testing device for measurement of a communication device for operation with at least one network comprising frequencies or frequency channels, comprising:

• means for performing a testing operation by measuring an operational parameter of said communication device under test in at least two frequencies or frequency channels, said communication device being adapted for a frequency hopping technique, said testing operation being controlled according to a pre-defined test frequency list according to the frequency hopping technique;
• and
• means for displaying measurements of the operational parameter for said at least two frequencies or frequency channels nearly simultaneously such that effects caused by adjusting or trimming the communication device in said at least two frequencies or frequency channels are observable in real time.

A method of testing operation of a communication device within a frequency band, comprising the steps of:

• (a) defining a hopping list of plural frequencies;
• and
• (b) measuring an operational parameter of the communication device at each of the plural frequencies by frequency hopping through the plural frequencies in accordance with the hopping list, wherein a period of time between frequency hops is less than the time required to measure the operational parameter at a single frequency, such that each frequency hop burst results in a partial measurement of the operational parameter at a single frequency, and an entire measurement of the operational parameter is formed at each frequency by combining partial measurements of the operational parameter from plural bursts at said frequency.

Method of testing a mobile communication device to determine performance of the mobile communication device at each of a plurality of frequencies or frequency channels, the method comprising the steps of:

• (a) supplying control information from a communication testing device to the mobile communication device, the control information specifying a testing operation involving each of the plurality of frequencies or frequency channels;
• and
• (b) performing the testing operation by measuring an operational parameter of the mobile communication device at each of the plurality of frequencies or frequency channels in accordance with the control information, such that a value of the operational parameter is determined at each of the plurality of frequencies or frequency channels, thereby determining performance of the mobile communication device at each of the plurality of frequencies or frequency channels.
