9.

Create a USB digital output channel for the Port 0, Line 0 of the USB digital output
device.

10. Configure the channel to be Active Drive.
11. Enable the output on the channel created in step 9.
12. Start the USB digital output task for the channel.
13. Sweep the signal source analyzer and read the marker. This value is the

OnPower

.

14. Stop the USB digital output task.
15. Clear the USB digital output task.
16. Repeat steps 9 and 10, disabling the output of the USB digital output channel.
17. Sweep the signal source analyzer and read the marker. This value is the

OffPower

.

18. Verify that the following equation is true.

OnPower

-

OffPower

≥ 80 dB

19. Close the device sessions.

Adjustment

This section describes the steps needed to adjust the PXIe-5654 to meet published
specifications.

Adjusting Frequency Reference Accuracy

This procedure adjusts the PXIe-5654 frequency accuracy performance using a signal source
analyzer. This adjustment yields a more accurately tuned voltage-controlled oscillator (VCO)
frequency.
1.

Connect the PXIe-5654 RF OUT front panel connector to the signal source analyzer RF
input connector using the K(m)-to-K(m) cable as shown in the following figure.
