Re: Thoughts About Modern Tek Scopes
prices of used scopes never go up because of "paying attention" to them or praising them on this forum or other forums.
the only things that raises their prices are publishing repair or upgrading

Re: Thoughts About Modern Tek Scopes
tds5054 for $1000!!!?? who in the world would buy that? That would be a rip off. Even TDS5104 doesn't sell for that kind of cash. This is not TDS7000 series,
although even TDS7054 is not worth $1000

Re: Thoughts About Modern Tek Scopes
Hi Jeff,
My post really was meant tongue-in-check, in reaction to Roy Thistle's earlier post. We've seen prices of some models of equipment increase after more attention was paid to them on the 'net.

Re: SUCCESS! The "sick" 475A is now the "fixed" 475A!
Rats, I hate when that happens. That's usually when I put things down and walk away. Time to clear my head. Hopefully if something is broken now it will be easier to identify.

Re: Thoughts About Modern Tek Scopes
Raymond,
all the scopes I'm watching have "Buy It Now" prices, so I doubt there will be any immediate increase.
I assume, however, that you think the prices would go up because you would praise this

If you have a printer, you can also do it in paypal, BUT, the problem there is paypal would see they're being shipped to people who paid F&F and charge Dennis the fee.

Re: Asking for Help with Verifying Genuineness of 2465B from Ebay
It's incorrect to say BW can be measured by measuring rise time. It depends on the 'scope's characteristics, the exact step shape (slew rate, over/undershoot, flat). Rise time gives an indication of

Chuck,
When I take the rise time measurement, I'm using the var knob of the volts/div in order to scale the flat top and bottom of the squarewave to the 0% and 100% graticules. I then use the deltaT
