A system and method to allow the control and command of a measurement instrument from a remote wireless handheld mobile terminal for obtaining, dynamically, the trace information, in the frequency and time domains, that represents satellite and terrestrial signals by means of a wireless communication with a server, in such a way that measurements and trace information taken by the measurement instrument are shown in real-time on a remote wireless handheld mobile terminal graphics screen. In particular, the invention provides the means for performing remote line-ups on up-linked satellite carriers, including the cross-polarization isolation measurements, from remote wireless handheld mobile terminals such as cellular phones or handheld computers (PDA) equipped with a wireless communication transceiver such as a cellular telephone or Wi-Fi (IEEE-802.11). The invention also provides concurrent access to a common single measurement instrumentation shared, transparently, by multiple remote wireless handheld mobile terminal users for performing simultaneous and independent alignment operations on up-linked satellite carriers without coordination with the satellite control center or hub station personnel.
