Is on the fly power sweep available with 5671RF Signal Generator?

[rajeshj]

Hello,

When I tried to sweep the power in 5671, the signal cuts of for a while and then generating the required power level because I have to change the power level by doing an abort, set power level and then initiate the generation. Can I generate without any dwell time?

Regards,

Rajesh.

Rajesh,

Have you tried the power sweep example program?

Let me know if this works for you.

Thanks,

Hi Travis,

I tried the power sweep program. It seems like power is sweeping without any cut off while seeing in a spectrum analyzer. With the same logic I have implemented AM and verified witht the same spectrum analyzer. I got the power sweep. I could see better result when I use attenuator hold. But at some levels ( say at the 5th step) there was a cutoff, but the time it goes off was very negligible.

With that I was satisfied to some extent and tried using for the squelch measurement with my receiver. We sweeped the power to squelch open and while decrease the power the squelch open at the first step itself, but expected is some hysteresis ( means the squelch should not close at the squelch open voltage level). I am sweeping the power at 0.5 dBm and also with 0.1 dBm.

I tested witht the squelch experiment with a stand alone signal generator and it worked. So I concluded that my receiver was not faulty.

Regards,

Rajesh.

Hi Rajesh

Just wondering, what frequencies are you sweeping through?  How wide a band and how many frequencies.

I have an example that shows how to quickly sweep through a single 20 MHz band.  Tune the NI 5600 and NI 5610 to a frequency, leave them at that setting, and then sweep the 20 MHz.
