Only if you pay for Terapeak... Ebay's for pay, marketing tool, that shows what items actually sold for... which can be surprisingly less than what the listing indicates. otherwise it's just Ebay

Greetings, What is the recommended substitute for the WG1306 diode? 120v 150ma trr=4ns Barry

For appraisals, my go-to is eBay completed items. You’ll see what stuff actually sold for. There have been no recent sales on the -D model, but a -C sold for $270. Seller was asking $300. Put it

> if I understand correctly (big if!), that intermediate frequency is produced by mixing the 2nd LO 2182 MHz output with the 2072 MHz input signal from the 1st converter. I'm trying to understand why

Did you mean 2467B? DaveD KC0WJN [email protected]> wrote:

Ok, thanks. Is there, given the serial number (109003), any indication that some modifications are already executed factory wise ? I will have a check of course on the components both of you

Rebonjour Wilfred Bravo for the new 465. Since the 1970s the successors were improved, so 465B has better control, LED not incandescent etc. Nowadays the last of the analog CRT scopes from

Wilfred, At the age of the scope, recapping is a good idea. The two 1.5A bridge rectifiers should be 4A types. These bridges are known to go bad. Increasing the capacitance is fine. If you replace

Sorry, I should have been more clear. I was looking at the manual step "Check/Adjust the Cavity 2nd LO" which says to connect a microwave counter to the 2nd LO output and measure 2182.0 ±0.5 MHz,

I have a TDS520D ( 2 channel, 500Mhz, 2GS/sec) that I am planning to bring to a local flea market to sell. I'm trying to figure out a reasonable asking price. Doing a Google search returns a very

If you want to finely adjust a 110MHz signal, a 7T11 time base would be useless with its very limited frequency accuracy and resolution. Raymond

If you want to measure frequency, then the 7D14 is probably the tool choice (to get in the ball-park anyway), but GPS locked counter will be better. David

Actually, a 7S11/7T11 combo will give you pretty accurate measurements of RF signals (typically better than a power meter). The signal needs to be large enough though, if you talking 0dBm that's

Hi Mark, thanks for the link. I'll have a good read through it. As for further failed tantalums, that could well be the case as the video amplifier is still not running correctly. Fortunately

Hello Mike, Thanks for your reply. I did some checks on some regulated voltages indeed in terms of voltage level and ripple or other nasty oscillation issues and all looked clean. However, not really

Hi all, I've been trying to troubleshoot an amplitude problem on my new 492, which has had multiple other little problems along the way. At this point, I can get a stable display and frequency is OK,

I prefer to use vintage equipment to calibrate my oscilloscopes, mainly because I enjoy the challenge. I just hate to see these golden age of electronics jewels going to the scrap and being

In the aforementioned link to enable options, follow the process as usual, but instead of sending the command 'WORDCONSTANT:ATPUT 327690, 1'. send 'WORDCONSTANT:ATPUT 327690, 0' (without quotation

James, I do not know if the 494XX type is the same or not in its guts. This site may help: http://www.ke5fx.com/49x_notes.pdf. Page 9 may be of help. The resistors he mentions should be increased to

Wilfred: All of the capacitors that you mention are part of the power supply, and their ripple is not specified, as they are part of pre-regulator circuitry.? Can you check the regulated DC voltages
