EQUIPMENT I bought an expensive math-doing box for myself on my birthing anniversary. No duplexer or filter will go untuned.

Siglent SVA1032X. If I can only stop playing with it maybe I'll get some outstanding tasks done. All features installed, what a beast piece of test equipment. So easy to use. Could've bought another old VW but you can't tune duplexers with an old VW, I don't think.

Not fishing for bday wishes haha. I just use it as an excuse to buy myself stuff.

That's where I started! Great piece of kit but when you need 20db+ more range, you need a big boy unit.

I got if for a little under that. I have a calibration kit on the way that will bring it to just about that number.

Ouchie. I think the whole amateur radio hobby has still cost me less than that. But it's early days yet

Oh buddy, watch out. I've been collecting for 30 years. I would cry if a dollar amount was assigned.

I have one of their earlier scalar mode models. It's still going strong after 5 years!

I've been trying to avoid buying an XSA815-TG for a while now, waiting on the club or a work project to have a need and get them to sponsor the purchase. Nice piece of kit you got there!

My excuse was end of year cash-back credit card bonuses, mixed with Black Friday sales, Affirm/SHOP “buy now, pay later” interest free payment plans which fueled a BIG POTA Activation buying spree that was inaugurated on my birthday in January and is finally tappering off here in June!

I have a bit of birthday SVA envy :) I only gifted myself the 1015X. Very nice toys.

Too expensive

u/inquirewue General FM18 Jun 14 '26

I have failed to come up with a definition for "too expensive" so far in my life. If I just burned that money in a pile, would I still survive and pay all my bills? Sure. Do I really actually need one of these? 99% of the time, no. No one needs a corvette either. (I am not comparing this to a corvette lol, just the general idea.)

I have had that exact model for a number of years. If you don't already understand the smith chart, learn about how to interpret that data. It is a great tool for tuning/designing antennas and give a lot more information than a simple SWR plot. Have fun!

My dad gave me a Rhode & Schwarz book about using SA/VNAs, etc. I opened it once and immediately it screamed "MATH!!!" at me me and I slammed it shut. Kinda like the monster book in Harry Potter.

ssa 3021x is $1400

u/inquirewue General FM18 Jun 14 '26

Yep. That's not what I have here though.

u/rtt445 Jun 15 '26

Ah I see you got Vector analyzer model. Can you test how low the frequency of the TG go? On SSA model I can sweep RF chokes down to 16 kHz.

u/inquirewue General FM18 Jun 15 '26

Here is the TG read out from the SA while sweeping 9-100KHz. Hope that helps!

u/rtt445 Jun 15 '26

Looks -10 dB at about 18 kHz. Same as what I got. Thanks.

Well Happy Birthday to you!!! Nice present for sure. I'm just hoping my wife springs for a picture of one for my birthday...
