Tiny Sa and a SDR are good pair. I think checking modulation close to carrier and checking spurs and harmonics are two different things. It is not IMO necessary to do both at same sweep.

That is the same? as what I see with my MSI.SDR SPR1 clone. But is soon as you apply an input signal the spurs start to explode

I have been experimenting with an MSi.SDR RSP1 clone from China for a short while and must admit I have only used it for relatively narrow span measurements. IMHO the RSP SA software has many nice

I tried a cheap RSP1 Chinese clone with the RSP SA PC software. It works very well for small RBW but when doing wider sweeps I saw many spurs and I was never sure if they where really there or where

Greetings, IMHO the major advantages offered by the tinyVNA concept are handheld portability and cost. The instrument concept is ideal for many portable field measurement needs. Professional field

That will take a bit of time to configure my linux system for that. I started with installed version to get a handle on "normal" operation. Doesn't have to work perfect that way only to get a

Yes. Please make sure you install the new FW as indicated on the wiki You can choose to use ch.dfu or ch.bin or ch.hex

Received mine today and installed a 450mah lithium battery for familiarization and testing. Quick question is the using set up to charge the battery from a USB

Have a look at this post where I show the side band suppression measurement using a softrock RXTX and a tinySA /g/HBTE/message/1126

I have been able to check side band suppression and carrier suppression by using a 2.5kHz tone as input. Of course this gives limited dynamic range but 40dB is possible for the opposite side band

========================================================== Erik, I believe he means that if your lowest resolution bandwidth is much wider than the modulation frequency then the modulation cannot be

Can you explain what you mean with "going close to the carrier"? Can you give a practical example?

Thank you all. I have checked SDRs in the past and I thought that only a few or one could go very close to carrier. Once again, thank you. For your info, I have one SA from Aaronia Spectran

Hi Erik, Sounds like you have the linear Y scale and sweep rate functions already nicely implemented! I imagine you will also come up with some innovative triggering modes. Best Regards, Tom,

Tom, I already added the ability to have linear Y axis. Triggering is something that makes sense in zero span mode anyway. In the setting/scan speed/point time menu option you can set the time per

Greetings Erik, Here are some additional comments which I hope are helpful: Although the screen view at " /g/tinysa/message/37 " shows a time domain capture of a signal the trace

OK, very good to know. Thank you for the information. Joe Joe Joncas WA7MHB Lincoln County Radio Amateur Club 541-272-3207 joe1@...

The tinySA uses a downconverter, selectable band pass filters and signal strength measurement all in one integrated device. As a consequence the output of the band pass filters stay's inside the

Below is the reason that I took interest in the tinysa. I had hoped to see and demonstrate how modulation works in the HF and VHF bands. The old SA that I have now can barely do that. Even if the

Hmmm, now that I think about it a bit more, the tinysa and an SDR could make a very nice complementary pair. Paul WB1EMK
