Fair enough, least not vulnerable being kept off the internet. I believe Win10 support finishes up soon. Cheers Dave [email protected]> wrote:

Dave, some do some don't, unfortunately some of the old R&S and HP do not work. I don't mind using an older OS in the shop,I do not need the newest, after all that computer never goes out to the

Hi John, Have you tried running the old apps in Compatibility mode under win10/11, I had a similar prob and worked fine in compatibility mode. Dave [email protected]> wrote:

*? Tested on Windows XP (Virtual Machine)* Just a quick note to confirm that the current 32-bit version of *WinSpectrum III* has been successfully tested on a *Windows XP virtual machine

Dave, there are two versions, one for WIN 10/11 and one for legacy devices like WIN7 and XP. Since most of my gear in my hobby shop needs WIN7, XP and in a few cases DOS I am maintaining the shop

The developers may have more qf an idea but I wouldn't expect recently developed S/W to reliably function on a OS less than Win10. Dave

I played around with a win7 computer in XP mode the 32bit version and my original ultra. Markers do not work at all, no matter what information entered. The curser does not stay hidden and shows up

Well done developing WinSpectrum, easy to use. The only very minor issue I've found is when selecting the Marker tab, the Accept and Cancel options are in Spanish, tested with 64bit Win11,?

Using an external attenuator is the preferred method with any RF generator. Some measure the output and use it as feedback to control the RF level, so that it is consistent over a large frequency

Of course, adding a resistor in an RF-path with impedance target is quite dangerous (only 0402 would constitute a limited risk). Regarding the 'roughly' 50 ohms output impedance: I forgot to mention

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
