I am a reader, not a sender of messages, usually. However the Windows application sounds (is sound the correct word for a written message?) very useful. What might make it even more useful is to run

Yes DC block for when measuring with any DC offset and at least 10, 20 and 30 dB 2 Watt attenuators. Leave the 10 dB always on the input and it will be safe. When trying to probe (low or high

Oh and can someone link to a 0-1Ghz LNA worth buying. And also a link for a backup 50ohm calibration kit? Or how do I test if i buy one to see if its 50ohms? Links to attenuator worth buying? And

Re: TinySA Ultra Calibration Fail.
Dear all, Finally the parts arrived, and I started the IC changes. First, I removed the U22 0 ohm resistor, working as jumper, and place the RF Switch, and do recall. During recall it fault again,

Re: What accessories do I need for a TinySA Ultra?
No need for self righteousness. There are RF environments where strong signals can flood an antenna. I can see why such devices would be useful. But I am nowhere near such a RF environment.

Re: Manual fault finding
Thanks. I inaugurated my cheap hot air station and the RF switch gently came off. Now i could jumper it to check the attenuator, but i prefer waiting for the spare part and soldering paste, and keep

tinysa ultra attentual and signal level fail
Hi I bought tinysa ultra from facebook. It fails attentuator and signal level. Can it be fixed? can it be used as a signal generator?

Re: Manual fault finding
Hi Erik, yes i performed the manual routine and think it is useful. I have a low signal level on my Ultra 407, down by 40 dB, i.e. at -75 dBm. Now your manual says that even with a bad RF switch, if
