Hi Martin, I know that dilema all too well. Gladly I was always so scared that I would damage this piece of equipment that cost more than twice my yearly wages that I would always start with twice the

Dave, Odds are I misunderstood what you wrote (said)? Here's the link/URL for the MiniCircuits model VLM-33W-2w-S%2B spec sheet: https://www.minicircuits.com/pdfs/VLM-33W-2W-S+.pdf No where in - on

Yes, addition of the limiter from MCL will add an additional 1.4-inches to your connector (I just measured mine). But it's good insurance. I don't know where Eric placed the inline attenuators in the

That's the dilemma with a lot of kit these days, it was a lot easier back in the day when a $50 attenuator could help save a $50K SA, and a fair amount of embarrassment from the operator's

While it is a little painful to add on another $100 worth of parts to a device that only cost me $150 maybe that's the price of reliability and longevity for this thing.. The other bummer about this

Well, yes, there is something more cost effective: buy yourself a low-capacitance snubber diode (not a TVSS, Transorb, or Zener - far too much capacitance!!!). They're made for the purpose and likely

My comment are regarding the below attached... The, MiniCurcuits: the VLM-33W-2W-S+, is ~$97 That's pretty pricey for our units... ___________________________________________________________

Yes, the tinySA's (classic and #ultra) are too cheap for its performance.

Er, nice thought but not particularly cost effective at about 50% the cost of an Ultra (or 2/3 of an Ultra via DigiKey - are they nuts??). Surely there's something a little more cost effective. 73

The 3 dB attenuator likely has a shunt resistive element at the input. Yes, this will help, but is not enough if the external antenna comes in contact with a "charged" surface, especially during dry

Please explain the use of a simple attenuator for ESD protection. It was my understanding something like? a simple 2 or 3 db attenuator on the input side of an Ultra was sufficient for dealing with

Regarding other interesting things one could measured/ listen to with our devices... Before the big earthquake in 1989 in the bay area/ Santa Cruz (1989 Loma Prieta earthquake), there was a big radio

QUOTE: I'm a sound engineer not an RF engineer let's just start there.. Wondering if I should be always using an attenuator on the input of my TinySA Ultra to protect it or only if I observe a signal

See below Better always have 10 or 20dB attenuator connected to the input Yes, but the damage could already have happened. Yes, but with a 20 dB

Using the antenna in a low power environment (mW), 10db is good. Use the device's LNA. Very helpful... For a direct connect you want to measure---for cleanest signals---something around a 10 MILLIONTH

yes, it would have been best to close (or rather delete) the topic from the very first post

Personally I always keep an attenuator connected, that's how I was taught, and it has saved me from mishaps on many occasions throughout my working career. You don't often need the full sensitivity of

Yes, indeed. You just visited the photo-electric effect. The light from the light saber (flashlight) freed a few electrons from the electrodes inside the NE-2. Uncontrolled conduction occurs (no

Hello, I'm a sound engineer not an RF engineer let's just start there.. Wondering if I should be always using an attenuator on the input of my TinySA Ultra to protect it or only if I observe a signal

I apologize, Erik, I did not see your warning until reading past the posts to which I referred my latest replies. Indeed there is some interesting effects as of late on the HF bands which one can see
