Power amplifiers that are universally used for radiated immunity testing either cover the range below 1GHz or the range above 1GHz. This means that if the test requirement extends both sides of this 1GHz point, the power amplifier needs to be changed over. Generally, this involves three connections.

- the RF signal from the synthesiser to the PA

- the RF output from the PA to the antenna/cell

- interlock/standby connections

The LETIS handles all these connections automatically. Each is switched via a high performance RF relay under the control of a USB interface. Software issued with the Laplace Synthesisers automatically detects the presence of a LETIS and handles the switching automatically.
