Please do not modify the tinySA HW, you will make it worse. The output impedance is roughly 50 ohm but for best impedance matching you can consider adding a 6 dB external attenuator. I never do this

A 64 bits update is now available. Additionally, following your suggestion Stephen, a 32-bit version targeting .NET Framework 2.0 has been added for better compatibility with older systems. Feel free

That means that the output is low impedance, i.e. not 50 ohms? Could I insert a resistor at an appropriate place behind the mux, in the signal path from the generator? -- Erstellt mit Operas

For good output impedance you must insert a attenuator of at least 6 dB -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Today, as I was going to measure the frequency (sensitivity) plot of a 500 MHz Keysight oscilloscope, I found that the measured amplitude was going to increase by approx. 6 dB from approx. 150 to 300

Ok, i got it. All references when not given are 0db = 1wThanksSent from my Verizon, Samsung Galaxy smartphone

The tinySA measures absolute power in a 50 ohm load and can display in various units such as dBm, volt and watt dBm is log of watt dB is relative. -- Designer of the tinySA For more info go to

QUOTE: So, the TinySA is probably relative to mW or -10db down from 0.001W = 0.1mW or 0.0001W ? ** NO N O......... NO..... N O Just POWERS OF 10 ! ! 1 Watt = 1.00.... Watts = 0

So, the TinySA is probably relative to mW or -10db down from 0.001W = 0.1mW or 0.0001W ?Sent from my Verizon, Samsung Galaxy smartphone

The standard of power measurement for most things RF these days is the: Watt or dBW Milliwatt or dBm This assumes measurements are made in a non-reactive (resistive only) 50-ohm system.

Quick dumb question. Since db is a relative measurement of power, in this case,? and I'm not sure to what standard that is, what units are tinySA db relative to? mW, W, uW or voltage or current level

Yes, only after doing a full range sweep and confirming there are no strong signals (above -20 dBm) you may remove the 10 dB attenuator if needed for the measurement. -- Designer of the tinySA For

Oh and can you use metal dust caps on the connection not being used when using a TinySA or NanoVNA? I have these nickle plated ones for equipment but was wondering if they would cause interference.

Those will work but can find much cheaper on Aliexpress.? Yahoo Mail - Email Simplified On Thu, Mar 20, 2025 at 7:38 AM, asron87 via groups.io<asron87@...> wrote: If I'm

If I'm understanding you correctly I should leave a 10db attenuator connected and then the antenna connected to that? Like this Constant Attenuator (10db)? https://a.co/d/fuqc3Gc (Or do you recommend

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

Hi, Our of the above mentioned items, I bought a set of EMC SMA probes for a few €. They are very useful for servicing radio equipments without disturbing their circuitry. You can measure

Erik.... are you really the guy that made these? That's awesome to be a beginner and get an answer from the creator. So thank you for that. What accessories would you recommend? Is a VLM-33W-2W-S+
