program NI-5660 with labview

[yy2822205]

I'm using NI-5660 RFSA. how to program RFSA with LabView to convert a
2MHz-wide block of spectrum centered at 14MHz down to baseband or other
lower frequency? Is it related to NI-TUNER? I can find the NI-TUNER VI in
labView but I can't find NI-TUNER by "Start > Programs > National
Instruments > NI-TUNER" for HELP information, how to solve it?
Thanks,

Hello YY,

I will suggest you open the shipped example called: ni5660 Occupied Bandwidth.vi
Then you will see three parameters that are common for Spectrum: Center Frequency, Span and Resolution Bandwidth. By specifying this, the driver will place the "Span" arround "Center Frequency" in base band in software, when in fact came from this higher frequency. NI Tunner will not play in this example.
In your specific example I suggest to make center frequency 14 MHz and Span of 2 MHz.

In brief, you specify the spectrum frequency you want to read and the hardware will do the rest. Then, you will get the data back into your program.
