Transmitting a Continuous Wave (CW) signal using ADALM Pluto with GNU Radio

Yes, there are two ways to accomplish this task.

1. Send a purely real tone to Pluto (zero out the I or Q signal).

2. Generate I and Q tones which are in-phase with one another.

Thanks for the advice Travis! Just to clarify with you, if I use those methods you have mentioned above and I visualise the output waveform transmitted from the Pluto's transmitter on my oscilloscope, would that mean that I would see the pure real signal riding on the carrier signal as it is being multiplied with the LO frequency before it is being transmitted out from the Pluto's transmitter?

My objective is to transmit a purely real tone out from the Pluto's Transmitter without the "Q"(Imaginary signal) signal and the carrier signal present in the output waveform when I visualise it on my oscilloscope. Any advice on that?

Yes, zeroing out I or Q will provide a signal at LO+tone frequency.

You cannot bypass the mixer stages, so if you want to view a baseband tone you will need another device.

Thanks Travis for the advice once again!

Hi John,

Kindly, can share with me the CW flowgraph? I am a beginner in this field and tried to find an example of the CW flowgraph but couldn't find any online. I just need a real simple example of how it looks like.

Thanks

Dear MJohn887,

are you able to provide me your chart? I would like to transmitt 1 CW signal but I am not able to get signal higher than -50dBm and from datasheet its possible to transmitt almost +9dBm. 

Thank you for help.

Hell, I just purchased ADALM-Pluto and I am trying to understand how to use it. I want to transmit CW signals using ADALM but couldn't find and information to help me doing that. Can you give me some guidance to do so. I am using Simulink and dowloaded the support package for this kit. Your help is well appreciated.
