I am still waiting for some advice. In the mean time I checked for poor connection solder joints. Clean the A4 timing board. [email protected]> wrote:

Hi Thomas. Long time. How are you? Thanks for the link.

I'm very interested in the topic of 'recapping.' I know there was a problem with some brands of electrolytic capacitors, coming from China, circa 1999... and that has an effect on those things

If you have an A or B series, you can get the calibration values back in the NVRAM with this utility (or with GPIB, if you have the equipment):

Hello Paul thanks for the info I have just ceck the 100 Mhz oscillator but thats up and running ? any other problems to check ? best regards Hubert

Jon, many thanks but: 1) I have hopefully a good capture video of all the CAL 02 values. 2) I found a lab that claims they have all the required equipment to fully calibrate it I was wondering: a)

Dear tektronix fans To introduce myself Hubert ON6JZ living in Belgium and an electronics repairer for 45 years I now have a tektronix 2712 on the table that does not work. It has been idle for over

What do you do with the values read from CAL/EXEC function. is there a way to enter/change them? I am asking as I have a 2465 as well that just had 04 10 which is describes by Tektronix as just out

Giuseppe For the parts, contact me yachadm AT gmail DOT com Menahem

Giuseppe, I did post a photo of the parts list for my higher s/n B model. The part prices and some parts will be different. Maybe some parts will have to have a different series due to Nichicon

Check to see if the 100MHz oscillator has output. It is just to the right of the CRT looking from the front. If there's no output then that is likely the source of the issues, but may be other

Old A 5 bd, battery backup, easy to change Use EXER function to read RAM cal.values, or gpib bus f has the option CAL requires correct test equipment, see service manual Usually a complete Cal

CHECKSUM I would kindly like to know, assuming I dumped correctly the CAL 02 values, if there is a sound method to verify the checksum for my scope before fiddling with the battery. Any pointer before

If anyone is interested in old GPIB adapter hardware and has a USA mailing address, I can offer for free: - HP 27209-60001 GPIB 8-bit ISA card, or - IOTech Micro488/EX Bus Controller (this is a

I run Linux with the linux-gpib driver, which from personal experience works fine with the NI GPIB PCI card and the Keysight 82357B. For windows, I'm certain other users can jump in with some

Well, my KISS-488 is one of those "pricey" adapters, at $129 single piece via my www.hxengineering.com, but it does way more than just USB. USB/serial at 115.2 KBPS, Telnet, HTTP (any standard

Yes, it also works with the 2465 (meaning not A or B versions). With the 2445 or 2465, you will get 200 calibration values returned instead of 256. If you don't have any options installed, I believe

Just for completeness of the information, what kind of cable is needed to do the GPIB backup into a windows PC? I know there are those rather pricey HP GPIB to USB adapters floating around ebay for
