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

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

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+

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,

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.

Trying to replace Input RF switch U22:? AS179-92LF LNA U14: BGA2817 might need to be replaced Attenuator U28: PE4312C-Z Good luck.

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
