Hi Jose, Sorry to revive an old thread, did you ever track down a copy of this software? I am trying to get a N4430A ECal working. Best regards, Roger

correct Jack, the processor is clocked, but apparently he can't acces the ROM (I think it is one of the 8355 ICs) and doesn't find the opcodes necessary to boot the machine. To correctly identify you

Hey Yves, I had some more findings in the meantime. I will do the proposed measurements later today. I was looking in the plt/print menu when I saw Show options, There i noticed that the SA displayed

Had a thought. Since I can measure the 3.333MHz clock signal, doesn't that mean that the uC is working?

Thanks Wolfgang! I suspect you are right. All of the voltages are spot on so it would likely have to be a failed uC.

as nothing works, it looks as if the processor is not booting. First check all supply voltages. A signature analyzer as for many instruments of this vintage will be of great help to determine what

Hi Marco, I'll look into a way to test the A12 module, but here are a few notes... The test you did injecting the 300 MHz reference directly to the Spectrum, the measurement on the screen was -5dBm,

Hey Yves, Thanks once more for all your fast and helpful replies! Many (paid) customersupport isn't as helpfull as you are. There is no jumper on a14W1, option 130 is installed and the jumper was

I could very well be that there is indeed a upgrade in PLL sensitivity or Sweep ADC. I can't open the 85102C as it is borrowed, but it is very interesting to understand the differences/improvements.

Anyone have a good deal of experience fixing an HP 1980B Oscilloscope? I’ve just got one and it worked for 5 seconds after I got it then the screen and buttons faded out. I replaced all the

Hi Marco, Just to be sure, is the A14W1 jumper there or not. Because, if there is a jumper installed at that position, it must be removed according to the documentation on that option 130. Yves De :

I recently came across this website and found it interesting. The user does not identify themselves so I am not aware as to if they may be a member of this group. There is an interesting category

There’s also a ceramic disc capacitor fitted between if memory serves, pins 1 and 4 on the back side of the motherboard. I don’t recall the exact value, maybe 1 or 10nF. The part specified has a

Found some info about differences between A and C, but not B versions of 85102. I think, you need to compare partnumbers of A16, A20 and A23 of both 85102B you have. A16 Remote Applications 85102A -

Hi Marco, The A12 module acts on a range determined by the Reference Level, between 0dBm and -50dBm. With the following configuration, I was able to verify that all the attenuation jumps are

To my knowledge there is no 8673 support at all in the 8510. Apart from that, the whole architecture is built around its source being a sweeper, not a CW signal generator. -Dave -- Dave McGuire, AK4HZ

Question - is your 85102 a "native B" model or an upgraded A model.? If it is an upgrade, there were two different upgrades for the A.? It is possible that only one of them was made.? There is an

Hi, does anyone know of the 8673G being able to be used with the 8510C please? regards Charles Edmonds VK3CLE
