Hi. I have this 492 which was working. Last week a friend donated a largely stripped 492 whose remaining parts I thought could be tested in the working unit. First thing to test was the

HI Bill, You said " but it quickly turned back to monochrome within a few seconds." Was that with the LCD screen fed from the VGA signals from the rear panel as I assumed (foolishly) that an external

Hii all, the PSU is now ok. After adjusting the DIP Switches the SA is starting and I can see the 100 MHz signal I injected. But I think the Signal is not locked. Down to 100 kHz ResBW the signal is

In the 22xx scope's power supply the 8.6V rail acts as a reference for all other voltages, so if 8.6V is low, all other rails will also be dragged down.

The possible options are only the ones which are listed in the datasheet! For example the number of sampling points can not be increased in a TDS6xx because of the other sampling technology of the

Yes, color Proc boards are different from monochrome. Thay have additional color video schematics. Regarding 1M and 2M, If we look inside the oscilloscope, we can see which type of memory is being

Yeah, shame about the probe for sure. I had the same schematic up and it seems quite do-able, just a handful of resistors, a cap, and a 6110. I'm not familiar with the plug type so maybe that's

As far as I know, the VGA output provides exactly the same image as on the CRT. So a monochrome scope will output a monochrome image via VGA. As for enabling options, the link provided above by

Speedy reply from VintageTek Museum, unfortunately it's: "We no longer have the volunteers who had the time to look for parts and ship worldwide. Sorry we can’t assist in these kinds of parts

Hey all, I picked up a RM15 (rackmount 515) a few weeks ago and aside from missing most of its tubes it is in impeccable condition. What's peculiar is next to the s/n is a plate that says MOD 801C.

I replaced the crt on my 640 w/ an LCD. I smiled for a brief second when i saw colored text on boot, but it quickly turned back to monochrome within a few seconds. I'm guessing this is exactly what

Dave, Yes, for 2F no any hw changes needed, only unlock by EEPROM modifying (don't forget to unlock EEPROM when modifying EEPROM ;). The color TDS with NuColor using non-VGA signals on the connector

You are missing the attenuator probe... so you can't generate the various calibration voltages. (So, how will you use it?) I've never seen one of those probes for sale. The plug is a Cannon plug, I

hi brian i am interested in model 2465b with serial b0655.... regards saroj [email protected]> wrote:

Thanks.

If you decide to sell it, I’m highly interested in it. I’ve been working on collecting Tektronix in house test equipment. It will have a good home.

HI, Thanks for your swift reply. So what you are saying is that :- 1). The FFT math function will already be installed and just needs 'unlocking' via one of the two methods you describe (2F Advanced

Hi Dave, You can unlock the options via GPIB. They are locked in EEPROM. See https://www.eevblog.com/forum/testgear/enabling-options-in-tektronix-tds500-tds600-and-tds700-series-scopes/ for example.
