I used a SBL-1 in a circuit to convert 10kHz - 500kHz signals up to a ham band - worked pretty good. Still works after about 50 years !

Great, thanks! i did not know it was that good.

Thank you!

I have an HP 3585B that goes down to 20 Hz. It's a great spectrum analyzer for everything from mechanical vibrations, to audio, LF/MW/HF, and on up to 40 MHz. But it weighs about 90 pounds so it's useless for anything I can't put on my bench. (I had to ask a friend to put it on the bench to begin with.) So this converter would be helpful.

Hi John, that HP seems very nice, goes so low!... bit heavy also :)

G,day from Sydney Australia.
This question may sound peculiar.
Is it necessary nowadays with components having such a wide band tolerance? e.g 50-6000 MHz
🤔💡

[@TonyAlbus]

Great isn't it. as long if the gain is sort of flat its usefull too.

Ik zou er een 10 Mhz tcxo inbouwen, scheelt weer een kabeltje en nauwkeurig genoeg voor zoiets.

Het is zeker een idee, maar je moet wel bedenken.
Het punt met een SA is vaak toch dat je het in sync wil hebben. of dmv gezaamlijek lab ref of de uitvoer van de SA.
Ook op hogere freqenties is een hertzje meer of minder wel okey, als je erg laat gaat zitten als 20 Hz ofzo... dan gaat het wel meespelen.
