1. In the "niGPS Write Waveform To File.v",   which format is the data written to the file , fixed-point or float point? 

2. In the "niGPS Write Waveform To File.v",  can I adjust the power of signal to test the sensitivity of the receiver?  If not, how can I do it?

    Thanks!

to 1) it's I16

to 2) consider using the property "Waveform Scaling Factor"

Thanks Christian.

Can you explain more about ""Waveform Scaling Factor" parameter?    How does it work quantitively to change the power of signal?  Its default looks like 0.5,  how many is the power of signal?  Thanks..

I am still confused if I16 format refers that the data is stored by fixed-point format.  Who know it.  Thanks!

i16 generally refers not to a fixed point format but to a 16 bit integer number.
