Hi Yan,
You should only pass only one value in the second member. Try :
pmt.cons(pmt.intern("freq"), pmt.to_pmt(2.4e9))
Cheers,
Timothée.

Yan,
simply convert "freq" and your frequency to a PMT before passing into cons().

Yan,
check the PMT manuals. cons()
Yan,
check the PMT manuals. cons() takes 2 PMTs as input.

Hi all,
I want to change the frequency in "USRP source" automatically, for example
2.37GHz-2.43GHz with each time stepping 2MHz.
1. As you know, the USRP source has an input message port, so I want to connect
it to a "Message strobe" to control the frequency change. But after I see
