I truly appreciate these videos. I have been waiting for a HP 3585A to come around for the right price and yesterday I found one. Months ago, however, I went to a forum and some members there were under the impression that I shouldn't get one if I didn't know how to use it. What a way to micromanage! Thanks for these videos.
Just found your channel, excellent content, thank you for posting. I am trying to calibrate a signal generator's modulated signal. I have been doing this on an oscilloscope. Generally, the modulated signal is calibrated at a certain percentage of full modulation. This can be challenging to capture on an oscilloscope and then one has to do the math. Can a spectrum analyzer automatically perform the math and display it so that you can immediately see when you have reached, for example, 60% modulated signal? Cheers!
I started watching your channel recently and really enjoy it. I'm torn on which SA to purchase. I'm looking at a used HP 8590L or new Siglent SSA 3021x ? Any thoughts? I'm a Ham and like to tinker in electronics. I retired from an electronic communication technician over a year ago and want to dabble with this stuff again. I just purchased a used Motorola R2670 service monitor as well. Trying to get my bench populated. Thanks.
In lieu of multi layer PCBs and PCB trace design, how do you eliminate additional noise frequencies in a circuit that you built, such as a function generator. Now I know that square wave and triangle waveforms in a function generator will produce frequency harmonics, but how would you reduce them? or perhaps if you were building a ham radio transcevier and you don't want to get into FCC trouble? I am a ham radio operator--KB2VNG. The 2 is because I live in NJ. Frank Reiser M.S.
What would be some decent models of analyzer to look for on the used market? Something bigger than a TinySA but not as expensive as the HP 8591E and its big brothers? I used an HP when I had a part time retirement job doing rf stuff at a local calibration shop but that is priced way higher than what I need for ham radio hobby use. Or should I just go with a TinySA for anything in the under $500 used class?
@@jdmccorful They serve different purposes. I have a dual trace 100 Mhz Tek scope so I am good there. A spectrum analyzer will tell you how clean your signal is a lot better than a scope. I learned electronics on a scope on Nike Hercules missile equipment in the 70's. My first intro to a spectrum analyzer was at the cal shop a couple years ago when I got bored after retiring from an IT job. I got over that quickly and went back to retired.
Well good brands are: HP/Agilent/Keysight Anritsu Rohde&schwarz Tektronix For just a quick check of things or portability the TinySA might be just fine if 350MHz is enough for you. For ease of use and fewer quirks a used SA will be better. I've owned 5 spectrum analyzers (7 if you count the two TinySa) from 1GHz to 40GHz. The older ones (before 1990) will not be synthesized and the frequency will drift so you will need to check the frequency with a counter or learn how to use a comb generator to calibrate. The HP8590 series was quite successful and most of the used instruments will be HP. You might also consider a radio service monitor like an IFR1500 or HP8920 My personal thoughts: used scopes - Tektronix used spectrum analyzers - HP
you can turn on max hold on the trace and transmit with modulation (talking). The analyzer will capture all the traces and you end up with the widest total.

Glad I could help!
Thank you for making basic videos! I was getting discouraged learning about SA, you changed that for me. Thanks.
A great follow on from part 1. Thank-you.
Just found you channel. This is great, your method teaching is extremely clear. I have the HP 8594E, it's virtually identical. Subbed. Thanks
You're the best sir!
Good teacher
Thank you very much!
Thanks very good .
Thanks for another video, would you mind repeating this section using the TinySA?
Thx!

I would get a siglent with a tracking generator

Good question, one that I am wondering about. Is an SA better than a scope for radio alignments?

Question . 12.5khz is narrow fm. Leaves room for deviation.how do you know your transmitting within the 12.5 khz
you can turn on max hold on the trace and transmit with modulation (talking). The analyzer will capture all the traces and you end up with the widest total.
Thank you Teacher! I am woodworker and I can follow just fine. Sort of. Please, Sir, may I have some more please?
I have 1600 videos so take a look. search my channel for 'spectrum analyzer'
Make Arduino SDR rf spectrum analyser using si4432 or something similar
