Subject: [TekScopes] Re: Birdies on a 492....what's normal?
I'm still learning my way around the groups. I may have sent replies
to individuals rather than the group. Sorry about that.
I went inside and checked all the cabling and found a few connections
that were a bit loose. Most of them were push-on SMB connections.
After tightening them all up, all the birdies flew away. :)
My 492 has mod UB and kit KE/FE installed. Would you happen to know
what those are?
What's the lowest power signal that this should be able to resolve at
minimum span, max resolution, and with the minimum noise filter
engaged and with video filtering set to narrow?
I'm asking because whatever it is, my HP 8640B won't go that low,
even at its -130dBM range with the vernier turned down all the way.
I'm impressed!
