NI PXIe-5653 Calibration Procedure
Reverifying 10 MHz Reference Amplitude Accuracy
This reverification ensures that the internal 10 MHz reference circuitry is adjusted for correct
amplitude accuracy following adjustment. Complete the following procedure to determine the
as-left status of the NI 5653.
1.
Connect the NI 5653 REF OUT 10 MHz front panel connector to the power meter.
2.
Connect the signal source analyzer REF IN rear panel connector to any rubidium frequency
reference output connector.
3.
Create a new device session for the NI 5653.
4.
Set the RF frequency to 4 GHz and commit the settings to hardware.
5.
Check the signal generation status and verify that there are no reported errors or warnings.
6.
After correcting for the measurement frequency, use the power meter to measure the
NI 5653 REF OUT 10 MHz front panel connector power. Ensure that the power is between
4 dBm and 7.5 dBm.
7.
Close the device session.
Reverifying 100 MHz Reference Amplitude Accuracy
This reverification ensures that the 100 MHz reference circuitry is adjusted for correct amplitude
accuracy following adjustment. Complete the following procedure to determine the as-left status
of the NI 5653.
1.
Connect the NI 5653 REF OUT 100 MHz front panel connector to the power meter.
2.
Create a new device session for the NI 5653.
3.
Set the RF frequency to 4 GHz and commit the settings to hardware.
4.
Check the signal generation status and verify that there are no reported errors or warnings.
5.
After correcting for the measurement frequency, use the power meter to measure the
NI 5653 REF OUT 100 MHz front panel connector power. Ensure that the power is
between 4 dBm and 7.5 dBm.
6.
Close the device session.
Reverifying LO1 Amplitude Accuracy
This reverification ensures that the internal LO1 circuitry is adjusted for correct amplitude
accuracy following adjustment. Complete the following procedure to determine the as-left status
of the NI 5653.
1.
Connect the NI 5653 LO1 front panel connector to the power meter.
2.
Create a new device session for the NI 5653.
3.
Create a list of test frequencies from 3.2 GHz to 8.3 GHz in 100 MHz increments, including
endpoints.
