3.
Connect the PXIe-5450 CLK IN front panel connector to the PXI-5650/5651/5652 REF
IN/OUT front panel connector.
4.
Generate a signal with the following niRFSG properties:
•
Frequency (Hz): 400 MHz
•
Power Level (dBm): 0 dBm
•
Generation Mode: CW
•
Reference Clock Source: Onboard Clock
5.
Use the spectrum analyzer to measure the frequency of the peak tone using the following
spectrum analyzer parameter settings:
•
Center frequency: 400 MHz
•
Reference level: +5 dBm
•
Resolution bandwidth: 100 Hz
•
Span: 100 kHz
•
Reference clock source: External
•
Frequency counter resolution: 1 Hz
6.
Verify that the measurement in step 5 is within the 9 ppm test limit, with respect to
400 MHz.
If the results are within the selected test limit, the device has passed this portion of the
verification.
Adjustment
To adjust the PXIe-5673 to meet published specifications, you must adjust the modules that
comprise the PXIe-5673 system. To calibrate the PXI-5650/5651/5652, PXIe-5450, and
PXIe-5611 modules individually, refer to their calibration procedures at
ni.com/manuals
.
Reverification
Repeat the
section to determine the as-left status of the device.
Note
If any test fails reverification after performing an adjustment, verify that you
have met the
before returning your device to NI. Refer to
for information about support resources or service requests.
