Verifying Frequency Accuracy
Use the spectrum analyzer specified in Table 1 to measure the frequency accuracy of the
NI 5404 module. Connect the SINE out of the NI 5404 to the input of the spectrum analyzer
using an SMB to SMA cable.
Generate a 10 MHz frequency using the NI 5404 module by completing the following steps:
1.
Call
niFgen_init()
to initialize the module you are testing and to create an I/O session.
Set the following parameters:
•
vi
—The output that is passed in by reference to the verification functions as
