I am at 07.74 on Firmware, so I should be ok. ?

the E will work just as well as the ES/ET and even the D will work but the D only works if you have the flash based CPU board , in any case the analyzer must have FW 7.68 or higher

I just looked it up and your 8753 needs FW 7.68 or higher for the ECAL to work as well as the 85097B PC interface , only 85090 series ECAL are supported

no , the older VNA required the use of either a 85060C controller or a 85097A PC interface ,? there were also some FW requirements on the 8753 as far as i remember?
on a side note i want to caution you on ECAL kits , having used ECAL on both Rohde and Agilent units i have to warn you that ECAL units are very easy to damage and extremly sensitive to ESD?

i have a 8341B that has SN 2804A however my 8510C testset requires a source with SN 2812A so i am trying to figure out what changes so i can possibly upgrade my 8341B?

Hi Roy,

In your subscription to this group, go to Advanced and you will see the maximum attachment size option, below:

…
Max Attachment Size

?? ?? ?? ?? ? Unlimited ?? ?? ?? ?? ? 0 (no attachments) ?? ?? ?? ?? ? 100KB ?? ?? ?? ?? ? 500KB ?? ?? ?? ?? ? 5MB ? ? ?? ?? ?

Maximum size of attachments sent to you in emails. For attachments larger than this size, links to retrieve them will be provided instead.

You can control the attachments which are sent to you.

Also, you can change Digest or Summary rather than All Messages, which allows you to choose individual messages.

Take care,

Larry

I'd be interested in the power supply if it is available.

Cheers!

This is what I got.

pin 3: 13.80V
pin 4: 13.05V
pin 5: 13.06V
pin 6: 13.83V
pin 12: 27.5V
pin 13: 27.77V

-----------------
Most likely U1 is good. You have one Vbe drop from pins 3/6 to pins 4/5 which is correct and collectors at pins 12/13 are balanced.

In the plots you attached I thought there was an imbalance in pin 4/5 voltages but the scales are different and they match. Input section looks fine.?

From a brief analysis of the output stage, pin 13 voltage swing looks too high (2.4Vpp), even pin 12 swing is high . U2 and surrounding components look like a transimpedance stage and should keep pin 12/13 swings very small. Given the signal swings, U2 is not doing its function, but it could be because of bad components around it so it doesn't mean U2 is bad for sure. I recommend looking around U2.?

DC voltages at pins 2/3/5/6/7 may give clues.?

This is a mailing list, not some web thingy. At least that's the way *I* access it, my mail program hits the groups.io servers and downloads this stuff...

While DSL was at one time considered "broadband", it's a poor performer compared to what some folks do with cable, etc. Unfortunately this rural location doesn't provide a whole lot of choices.

The point here is that when one of you guys attaches a multi-megabyte file to one of these emails, I get to download it whether I want it or not. Which ties up my connectivity until the download is done.

I don't mind the occasional pictures and such, but those big files are something else!

I'd appreciate it if you guys could simply put such large files where somebody can get at them, and provide a link, for those that want it, rather than forcing those of us who get things this way to download for no immediate benefit.

Last night I upgraded the monitor on my 8594E to the NewScope LCD that you find for sale on eBay.? The SA was in good shape but you could not read the text on the monitor because of burn in and no focus. I have many years of experience in TV repair but this CRT had no hope. The install of the LCD went well, just some adjustments of the no glare screen was needed.? The new image is one thousand times better than what was there.? Some people say the price is too high for the LCD but I saw a NOS CRT for sale at the same price. I rather go to the modern LCD.? The NewScope LCD did not come with instructions. You had to go online to get them.? Also you will need the service manual to remove the old CRT and disconnect various connectors to prepare the SA for the new LCD. You have to have a iron ready to jumper a resistor on the video board with another resistor.? So the install is not plug and play.? I think I was done in a hour and a half but I was taking my time.? Did not want to mess up something.? I now have an old CRT sitting in the floor. Who wants it?

Some time ago, due to the SYTF failure on an 8596E, the modification was proposed to transform it into 8593E, using the YTF, more available, the modification also consists of removing R485 and putting R515 (unclear), the problem is that these R in A7 card 08595-60022 do not appear.
