Just compared the spec sheets and they are almost identical - even the ordering of the specs is the same.? Performance graphs have slight variation.? Digi-Key has stock and they ship overnight for a

Attached is a translation of the data sheet.? You can get 5 of them shipped to the USA by registered mail for $9 USD.?? If you want them quick FedEx or UPS is also available but costs much more.

Reading the FAQ: Under general questions the AS179-92LF is listed as the internal switch. Under tinySA Ultra questions input switch U22 is type number XA17-G4K. I cannot find a supplier for the

BTW, The generic level correction tables were based on the assumption that the manufacturing tolerance would be within ~+/-2dB for all devices and preproduction testing on a small sample of units was

Ed, If you don't mind, I'd be interested whether you noticed the same discrepancy if you used one Ultra in the signal generator mode and the other in the spectrum analyzer mode and then reversed the

I did this earlier with the help of nanovna, I used 3 harmonics

For those who do not have a specific source to generate 5.34 GHz, they can use the tinySA classic as source, if they have one. 5.34 GHz / 6 = 890 Mhz 5.34 GHz / 7 = 762.857140 Mhz. Using HIGH OUTPUT

Thanks for the idea, Jeff. I did some tests with an attenuator in line to reduce the input signal level and still observed the discrepancy. Ed, K0KC k0kc@... http://k0kc.us/ | |

I received a replacement synthesizer from Q5 Signal today and ran some tests which definitely showed that the two TinySA Ultra devices respond differently at the higher frequencies. I made sure that

OH Hell! I forgot to tell you to download thee dfu utility. Go to where Erik told you to go. larry

Erik, you may have seen my posts in this thread: /g/tinysa/topic/97851892 Trying to measure a? 2.2 kHz tone at 2.5 to 3 kHz deviation, sometimes the 3 markers would be all on one

Jim is correct. Having been in the two-way radio business (years ago) I know about pre-emphasis.? You'd think I would have considered that before making the comment about the deviation being the same

I thought this might be of interest to group members.? It is an easy to read tutorial on? three methods to measure Noise Figure.?? Two of the methods are applicable to the tinySA.

As do I. ?On the wiki page is a command: *dfu-util -a 0 -s 0x08000000:leave -D tinySA.bin . * Download the firmware and remove the part of the title showing the version number i.e. everything after

Wim Thanks for the feedback, I will improve the spec. -- For more info on the tinySA go to https://tinysa.org/wiki/

Eric, Where can I find the tinyPFA release? Mike N2MS

In the spec of the ultra rf -generator is says step size of 44 Hz, but i measured 57.2 Hz. Step size of 57 Hz, gives freq gaps on chosen output frequency between 0 and +28 Hz or 0 and -28 Hz. My cal

Looking good Thanks Erik
