1. A signal generator for broadcasting signals to a device under test, said signal generator being configured to test said device under test for location based services by simulating multiple access points, said signal generator comprising:
- a broadcasting unit configured to broadcast a single composite signal to said device under test, the broadcasting unit having a single broadcast antenna;
said signal generator comprising a controller unit configured to create said single composite signal which emulates several individual signals that do not come from said multiple access points but are generated by the signal generator to simulate coming from said multiple access points, said single composite signal being a multiplexed composite signal,said controller unit configured to forward said single composite signal to the broadcasting unit to broadcast over said single broadcast antenna, andsaid signal generator configured to use a single baseband for transmitting said single composite signal, such that multiple broadcast antennas simulating several access points in a test system are not required.

16. A method for testing a device under test, for location based services by simulating multiple access points, the method comprising:
-
providing a signal generator for broadcasting signals to said device under test, said signal generator comprising a broadcasting unit configured to broadcast a single composite signal to said device under test, said signal generator further comprising a controller unit configured to create said single composite signal which emulates several individual signals that do not come from said multiple access points but are generated by the signal generator to simulate coming from said multiple access points, said controller unit being further configured to forward said composite signal to the broadcasting unit having a single broadcast antenna; and broadcasting said single composite signal that emulates said several individual signals from said multiple access points, in order to test said device under test for said location based services by simulating said multiple access points, wherein a single baseband is used to transmit said single composite signal, and wherein said single composite signal is a multiplexed composite signal, such that multiple broadcast antennas simulating several access points in a test system are not required.
