Can't you use the "shrink to fit" print option in Adobe Reader?

In the UK "Doxdirect" print stuff for me quickly and cheaply and I suspect there will be equivalents throughout the world.

Luca, After booting with the jog weel pressed to the side do a CONFIG/CLEAR CONFIG and a PRESET/STORE/STORE AS STARTUP This should solve the crash on boot problem. --

Hi Erik
Sorry fo the late answering, I'm currently touring and have little to no free time
Since last time I wrote you my tinySA has been working nicely and only recently has started again prompting me the stack dump, every time I've managed to start it again by holding the jog wheel right during boot; I still haven't managed to snap a clear screenshot of the stack dump, sorry (touring life...)
Currently is easier for me to try and resolder or replace the diode, since i have both soldering stuff and diodes with me on tour and I need the tinySA daily for work
I'll keep you posted
Thanks for the wonderful assistance!

Re: Measuring SSB 8W Tranceiver Power
#ultra
8W will destroy the TinySA, the absolute max i/p is 100mW, but this level is way too high for accurate measurements .
To get to a sensible level you will need at least 60dB of attenuation!!

Re: Measuring SSB 8W Tranceiver Power
#ultra
The max input power is specified on the case of the tinySA For a 8W transmitter you should indeed use at least 1 external attenuator. To be safe, calculate the external attenuators such that the input level of the tinySA is below -20dBm This because you may want? to measure harmonics and for this you need the headroom of the internal attenuator to check your measurement --

Measuring SSB 8W Tranceiver Power
#ultra
Hi,
I am just starting out with the TinySA Ultra and still working my way through the documentation and videos which are great! Thank you.
I was looking at video #14?Testing a Transceiver and noticed that with the TinySA connected directly to the transceiver, on transmit, input attenuation on the TinySA was at 30dB and power was measured at 1.9W, which looked like max scale.
My question is, can I connect the TinySA Ultra directly to an 8W SSB transceiver (40m band) the same way and measure the power (W) or will I need external attenuation between the transceiver RF out and TinySA Ultra as I suspect? I was thinking of using a 50 ohm 20dB 10W attenuator followed in series with more 'low power' 20dB and 10dB attenuators if needed. Would this work and if so what sort of reading (W) would I expect to get on the Ultra at 8W TX?
My thought was to use the Ultra to align the BPF (Band Pass Filter) on the 40m band (7MHz) and also check the transmission power.

Re: TinySA Ultra Menu-Tree Chart pdf file in landscape mode
? Hi Ctoyan No TinySA ULTRA does not have a 1Hz RBW. When measuring phase noise it is common to normally the standard to mathematically convert the measurement as if the TinySA ULTRA had a 1Hz RBW. The various RBW has all an equivalent conversion factor in relationship to 1Hz RBW. It is a rather complex mathematical process being done in the firmware Kind regards Kurt ? ? Hello
Kurt, Thank you very much, especially for info about calibration!
One question about page 8 - is it true Ultra has 1 Hz RBW?
In the specs minimum RBW is 200 Hz...
May be it mean 1 kHz?

I also don’t have experience with editing PDFs, but I could print the pages, mark them up by hand, then scan those. Would that work for you?

Re: filter measurements with tinysa ultra
Hi Dave,
I have in the meantime 3 of them. TO be more precise 3 TinySAs
and 3 NAnoVNAs. :-)
It is so amazing? what can be measured with this little units!
In many cases they outperform some 20 years old heavy units,
degrading them to paperweights.
I have one TinySA all the time at my audio equipment repair
place, to test for rf oscillation.
The Ultra is with the NanoVNA 2 in my tool box for installation
and service of locking systems, to monitor the ISM band for
communication in this systems and to check the antennas.
The other two boxes are ión my RF test bench as handy tools to do
fast checks when repairing RF measurement equipment. I love the
fact that the TinySA has no grounding, so it dosn't make graund
loops.
To conclude, it is a good idea to have a lot of this little
helpers around :-)
All the Best,
Isidro

Thanks for all the replies and guidance.
Agreed - I think Erik has covered noise pretty well and
I'll be sure to follow his video and warnings (especially
total power). This seems like the best approach using the
Ultra.
Thanks for the note about a slow sweep and max hold. I
hadn't thought of that.
I haven't gotten around to getting a nanoVNA yet.
Maybe?it's time! It's definitely on my wish list.

The total power the SA can see is
the result of all frequencies the noise source

He published it within the last two
weeks I think, but I didn’t keep it.
You can also use a well calibrated

Can the tinysa ultra be used with
a tracking generator or in some other swept mode?
I see the video for the tinysa.
Also I see the ultra has an "LO" checkbox. Would
one use that LO out to drive a mixer or does the
ultra accept an external LO?
I'm interested in sweeping a
filter. I've seen the noise-generator based method
so perhaps that's the best approach.
