Thanks Herb Erik has kindly told me Thanks Dave

The hardware design for the tinySA Ultra is not open source so I really can't say.? Suffice to know that the CAL output derives from the main clock source, so by monitoring it while using Eriks

Ok thanks Erik I can not wait until this ultra arrives, as my spec an in my HP test set has only got a span of 10mhz, it does go up to 1ghz, Thanks Dave 2E0DMB

30MHz TCXO -- For more info on the tinySA go to https://tinysa.org/wiki/

Search for the level correction menu in the wiki -- For more info on the tinySA go to https://tinysa.org/wiki/

To reach the required resolution both the LO and the IF are "tuned" where the LO does the course steps. So you never can scan a small span wit a TG using a fixed IF frequency source I do not recommend

I got within 4 Hz at 100 MHz.? Now, how do I calibrate the amplitude? Wes? N7WS

Once I figured out how to do it, it works fine. Wes? N7WS

Hi I have been reading this as I have just ordered the ultra yesterday, Can you tell me what frequency does the main clock oscillator run at, Thanks Dave 2E0DMB

My understanding is that any time there is a change in impedance, there is a reflected wave.? This is the definition of Gamma, the Reflection Coefficient.? The RF power amplifier has a certain

The frequency correction setting is lost after each firmware update.? You can save yourself some time by writing down the CONFIG->MORE->EXPERT CONFIG->FREQ CORR value that got your error down to 9Hz

Hi Alex, I will try to explain my setup. First a bit of background: I am a professional firmware developer for many decades. I have been using SVN (TortoiseSVN) for many years without any issues. I am

Thanks, Erik! I was able to get the error down to about 9 Hz. -- Ed, K0KC k0kc@... http://k0kc.us/

The tinySA Ultra has a minimum output frequency step-size of 44Hz as stated in the Wiki.? ?So, if for example, after frequency correction you are still 20Hz off you will not be able to get any

It will correct both input full range and output below 800Mhz and "highest accuracy mode" above 800Mhz in the same way. Cleanest signal mode above 800MHz is less frequency resolution. I need to update

I would like to calibrate the output frequency for my new TinySA Ultra when in Signal Generator Mode. I am using an amateur radio Flex-6700 for a receiver which is disciplined to a GPSDO. The

Thx Erik, My build of v1.3-563-g1da836e for tinySA looks also good. Martin

All very well. I liked the new text font, it greatly improved the visualization of the number in Big Number mode. do you consider putting the marker frequency display in big number mode?

A tracking Generator is possible to be build but not for low span and resolution. Whenever I go below 1Mhz span I see chopping of the trace even if the external source and the IF are within a few khz.

New ULTRA FW release Version V1.3563 Changes: - Improve touch defaults so touch calibration is not needed after FW update - Marker ->Ref level now sets ref level to exact level of marker WARNING: this
