Operation
1. Connect all cables as shown below.
2. Switch all units on.
3. The LETIS should default to Auto, Emissions mode.
4. The system can be used for emissions testing only at this stage.
5. For auto operation and immunity testing, connect the USB cable from the
LETIS and the PC.
6. Run the RFSynth software.
7. The LETIS will switch to a power amplifier only when actually running an
immunity test.
8. If you need emissions testing, simply close the RFSynth software.
9. For immunity testing, leave the mode in Auto. The power amplifiers will
automatically switch at 1GHz.
NOTES
∗
If not using the RFSynth software, the mode selector switch can be used to
operate the system in Manual mode.
∗
If the switch is used to exit Auto mode, the RFSynth software must be
restarted to resume Auto operation.
