Hi Erik I have just written a 30 page document on the TinySA with 95 illustrations for the HAM magazine OZ and in this connection used the markers a great deal. They work excellent (using latest firmware) However MARKER OPS is killing me I have not yet found the “secret” behind the idea as it is screwing up the display setting ? I need to spend more time ? Kind regards Kurt

Kurt, ? I'm sure the article will be well received - as is generally the case with your technical publications.? Here's what I have found out about marker ops. 1.? Marker OPS -> Center:? This operation is the one I use most often and is probably the one you are also familiar with.? It makes the current active marker frequency the display center frequency.? I primarily use it to make the active marker frequency the center frequency and then zoom in on it using Frequency->Span button. 2.? Marker OPS -> Start: This operation makes the current active marker frequency the display start frequency.? It took me a while to figure out a good use case for this.? If the active marker is a tracking marker it will move that frequency to the first display point and track the next highest signal to the right.? 3. Marker OPS -> Stop: This operation makes the current active marker frequency the display stop frequency.? For me it has a similar use case as marker->stop.? If the active marker is a tracking marker it will move that frequency to the last display point and track the next highest signal to the left. 4.??Marker OPS -> Span: I expected this operation to change the SPAN setting relative to the current active marker frequency.?I haven't figured out what that relationship is.?? - Herb

Hi Kurt ? Congratulations on your article.? I did a web search but could not find the HAM magazine OZ you spoke of. ? Hoping you can provide a web link for the magazine and your article. ? 73 George ?

Kurt,
you may have replied to Joe, but not as part of this thread. ;)

Hi Karl Sorry, that is because he might have used the subject line then my mail rules put it in the TinySA folder Well, the answer was The OZ is the official Danish Ham magazine like the QST is in your country. My article is in Danish and that language is when spoken called a “throat disease” ?
I might do a English version or a Video which I can dub in different texted and spoken languages.
I am presenting the TinySA at a seminar on Sunday arranged by the Dansk HAM organization EDR and am cresting some power point and video’s so I have then some material to “glue” together in a public presentation. So wait and see what I can figure out to release. Kind regards Kurt ? ? ? Kurt,

Hi Herb Great thank you, now I understand see the possibilities If I figure out the span I will let you know ? Kind regards Kurt ? ?

Hi Herb - Span is described in the WiKi as “Keep the Center frequency but set the span to the offset of the active marker” It is the offset relative the center frequency. If there is two tracking markers then these marker frequencies are set as start and stop frequencies.

? Thanks Kurt, ? ? I read the wiki but I misinterpreted the meaning of "span to the offset".? With two markers displayed it makes sense and is very useful. ? ? - With two markers displayed, selecting Marker OPS->Span will span the start and end frequency range to the lower and higher frequencies of those two markers, respectively. ? ?- Herb

This marker ops behavior is copied from the nanoVNA, I actually never understood how to use it, except for the "CENTER" ops.
Glad you guys helped me understand.....

Hi Erik Yuo are wellcome ? I am producing videoclips right now and I am afraid the Unit V and W are corrupted one way or the other. There are some weird interactions so when changing level per division the ref level changes. Maybe I have forgotten how to do, or I am too tired at this time of the night to figure it out… so Good night Kind regards Kurt ? ? ?

Kurt, ? ?From the beta testing phase, I seem to recall that for V and W units Erik cautioned the following: ? ?1. The units are linear so measurements are best performed in the time domain (zero-span). ? ?2. Both the reference level and and attenuation can only be set in discrete steps of 1, 2 , 5, 10 and they interact to maintain a vertical scaling of 10 divisions.? This can sometimes make it difficult to get a waveform positioned in the display exactly where you want it. ? ?The conversions with reference to a 50Ohm system were correct the last time I checked - unless something has changed recently. I forgot to take notes when Erik was explaining the exact workings, so I'm sure he'll correct me if I miss-spoke.?? ? ? - Herb

There is a bug that causes strange auto reflevel behavior when in linear mode and changing the scale from small to a larger value. E.g. from 2 to 10. This causes the reflevel to reposition after one sweep after changing the scale to try to maintain a multiple of the scale

Hi Erik and Herb Thank you both for the info, which I was aware of. The problem I had was that is did not realize the Ref level and level/division is fixed and frozen by a factor of 10 and no other ratio can be chosen. That is a vital info to convey for a noval user and that I will include in my video clip on the linear Unit modes Kind regards Kurt ? ?

Its a bit more complex. Normally linear modes work in auto reflevel/scale mode where the bottom of the screen is at zero and the reflevel is 10*scale. This because you can not have negative values in linear scale. When you change the scale the reflevel setting moves to manual!!!!! You can set the scale and reflevel to anything as long as the bottom of the screen is zero or larger. If you set reflevel back to automatic it works with the selected scale and the reflevel can only be a multiple of the scale AFTER the first sweep in auto reflevel mode. So if the scale is very small (as can be in a linear scale) it will take many sweeps before the signal can become visible again. This is something I may improve in the future. If all signals are off screen and reflevel is automatic I jump after one sweep to a visible signal. This is all kind of complex but I did not know how to do it better. Any suggestions?

Hi Erik Thank you very much for this info. I will print this info and give I a trial. Thank you once again Indeed it is a complex instrument, and Auto is indeed a huge benefit to the novice and eventhe ?more experienced users Kind regards Kurt ? ? ?
