1. PXIe-5654 RF Analog Signal Generator
2. Power Meter
3. Power Sensor
2. Create a new device session for the PXIe-5654.
3. Configure the PXIe-5654 using the following settings:
•
Frequency: 4 GHz
• Power Level: 0 dBm
• Reference Clock Export Output Terminal: RefOut2
4. Initiate signal generation.
5. Disable the RF output.
6. Check the signal generation status and verify that there are no reported errors or
warnings.
7. Use the power meter to measure the PXIe-5654 REF OUT 2 100 MHz front panel
connector power.
8. Correct the power meter reading for the 100 MHz measurement frequency. Ensure that
the corrected power is between 3 dBm and 7 dBm.
9. Close the device session.
