Re: 8516A cable question
With the 6 foot cable my system seems to be about 40% working. From 20-40GHz S12 and S22 sometimes fully work. S11 and S21 only up to ~30ghz works, then the NO IF FOUND errors comes up. Changing the

BTW the 4438C has reverse power protection but there are a few differences depending on the frequency! The 4438C was available in 2GHz , 3GHz , 4GHz and 6GHz , versions to 4GHz were protected up to

One word to this subject, some generators had RPP offered as option so you might want to double check

If component level data is available, look at the diagram and parts list to determine the type of DC protection. Cheers! Bruce Quoting Radu Bogdan Dicher <vondicher@...>:

I guess my question would be why you want sweep to begin with ? If you want to measure filters than sweeping is only half the rent, you still need some way to display your response in a dB linear

Honestly, probably worth its separate topic is how many of these units have AC and/or DC protection on their output. DC - far more important in my book. In a hobby environment of experimenting and

Ruben, You're right, there's just two sweepers on that list, which complies with my original requirements. But I decided to keep the list a bit "looser" than how I started it; besides, there's just

They usually do; people have to learn somehow. But who do you think is writing that example code? Adafruit and SparkFun are staffed by far younger people than you and I. It's not all gloom and doom.

So you are telling me that the modules sold by adafruit or any of the other stores don¡¯t come with any example code and integration examples because I sincerely doubt this

I am not trying to be dismissive or negative just stating observations , as far as driving kids away I got a 5 year old grand daughter that just learned how to solder a DB9 connector for a wiring

ABSOLUTELY DISAGREE - Different yes - less challenging or technical NO. Natively the module knows little except a protocol at sole level. DOING something with that basic functionality is the

If it comes to DSP or SDR one line of code wont get you too far ? SDR is a amazing field and you can do a lot of things which is why the technology has been found its way into both military and

Re: BS, was Re: [HP-Agilent-Keysight-equipment] Spread the word -- Swap Meet Returns!
I agree, but that's not all they're doing. Don't be so dismissive; the only thing that will accomplish is make you bitter and drive the kids away from their interests. -Dave

Buying a Bluetooth or zigbee module and tacking it on a mcu module is not the same as designing a circuit all the way to the circuit board and then building and testing it just saying

Absolutely agree with Dave - how any of the buiders canwrite a line of code, that might just replace a piece of hardware or make it easier to use ?? Quoting Lothar baier <Lothar@...>:

...and Bluetooth and Zigbee and LoRa...They certainly ARE doing RF, just mostly not the same RF that you did. And that is ok! True, all true. But to assert that it's somehow not an area of interest

They might be building stuff but nothing that has to do with RF , maybe microcontrollers robots and drones .... As far as HAM RADIO goes ( and I am a HAM btw ) 'giving them out " is about correct

No, the kids aren't buying microwave parts at hamfests. This is what I was meant when I said "it is DIFFERENT now". They are buying parts from Adafruit, SparkFun, and Amazon, and hundreds of other
