My 53310A is normal again! I have to wait for next chance to find out what causes the problem. Jack

Hi Peter, Honestly, for sure I'm not. The last time the same problems arose, I finally had to have the YTO repaired. Now I would have a replacement here in case of a case. Armin HB9MFL

Yes and thanks guys, the 3488A is a very robust instrument - virtually indestructible.? Never was an I/O card ever sent back for warranty repair or for out of specification replacement.? Those

Alex, Those Vishay resistors from China are the real deal.? They are pulls and affordable.? That is if they are from the company I have purchased them from previously.? ?A year ago I purchased

Hi Gerald, I sent you an e-mail from my private address, to get news on the manual, but I didn't get an answer. I don't know if they arrived. Dario IU3ARP

I am looking for information to trouble shoot scope that just quit? there is no help or drawing in service manual

Hi Tim, I used two 3488A units for several years, this was a very reliable instrument and very useful. You and your colleagues did an great job with this 3488A. Congratulations ! Regards Yves De :

Brilliant George, Sounds good and if you have a small amount of time during the visit we can potentially meet up. I am only in Stevenage/Luton area (approx 30 miles north of London... simples.

Nigel, I will see what I can do.? The same connector blocks were used on the HP3421A portable data acquisition unit so look out for those.? Unfortunately when you purchase cards, the connector

Hi George, Very nice explanations. I will follow your advice and calibrate the 3478 as well on 4W. Its just that I was a bit less trusting about its calibration than the 3468, so my reasoning went to

Seconded! I have two, and love 'em. They are wonderful units, damn handy. Nice work George and team. -Dave

Hello, now I am awake again. IMHO; the next test we must do is to check if the CPU card is farting out a video waveform. If you see the "marching ants pattern" on the LEDs of the card, it is very

Hi George, Congratulations on a nicely executed design. I love it... simple to use and straightforward to fix. As i said,i have two chassis with various switch or i/o cards in each. What i don't have

Are you sure it is the YTO? Peter

Newly this error appears. Does somebody has a reliable source for spare YIG. In may vna is a 5086-7718 mounted. Armin HB9MFL

Tim, Tell me what it is you are looking for and I can help you.? I was the analog design engineer on the HP3488A. I designed the 444XX series of I/O cards and have a large supply of all the parts for

George, Nice work. I still have a few, one of my sons used a couple for a High School project with a 3456A to plot the discharge curves of several different types of cells. These are a great bargain
