Just took a whack at it myself. It went better than my "08340-90021 Vol 4 Process Attempt" I think. Peter and Dave, both of your processed files appear good to me. That final schematic (page 26

Hello Yves, Thank you for your screenshoot. Here is what I got on my board. TP20 B (with look cable between port 1 and port 2): TP18 A (OPEN loop between port 1 and port 2): TP16 R: I check the

Don't know where I read this, but it said: better use high resolution with JPEG compression than low resolution without. For the same file size, that is. My experience: 300dpi is largely sufficient

Sorry, test point TP12, TP10 and TP11 are ground from sampler…no signal on that. Input signals are on TP16, Tp18 and TP20. Output R, A and B are -6dB lower than input (TP 9,8 and 7). Signal at

If anyone has a copy of the manual for this old amplifier I'd appreciate a copy.? Even just the schematic diagram would be appreciated.? I have had this amplifier for years and use it once in a

I should have said: [...] scan 600dpi, ==greyscale== .tiff-s !!ONLY!!

I don't want to have to dig for that so give me a link, I'll post process and get back to you. I have long since and flat out mastered document scanning and restoration, I've done 1,000s upon

No, the "tabs" are not re-usable. They're a part of the battery. I've replaced these in a variety of equipment, unsoldering them and then installing a socket and new battery as you describe. The

If the three signals are absent, there would have to be a common point between them, so there is the local power supply. Signal A, B and R on DIGITAL IF come from of the 3 outputs of samplers

Using JPEG for those will result in nasty artifacting around the text, border box, etc. I'd not recommend that at all. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Yves, Thank you for your analyse. I have exactly the same board as you for A10. The ADC test pass with no problem. I was not able to get any signal with the scope on TP R, A or B. Quite strange!

This is version of board DIGITAL IF of my 8753ES.

Hi, To make a short summary: You have tested several RF paths, <300kHz, <16 MHz, CW 1GHz, sweep up to 6GHz. In all cases the signal is noisy for all S parameters, but always PHASE LOCKED.

I didn't bother with any sharpening; the original scans really aren't too bad. One example of a page in that document that has a schematic is page 20. I did a quick pass in GIMP on each TIFF

I've had a play with GIMP on Linux, and I can (to my eye anyway) sharpen things up quite nicely. But, as yet, I've not hit a file with a schematic!. Can you tell us which file(s) have schematic

I sure would like to get my hands on one of those scanners. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

I took a whack at it and didn't get anywhere near as much of a size reduction as you did. But, the file looks great, passes a PDF/A validator, and has been OCRed. And, no embedded ads. ;) I've
