Update. So I think I've got it figured out. The service manual is a bit confusing as it only references the older 486 style processor w/computer function which requires a graphics card. Newer Pentium processors with the attached daughter board do not. Turns out the processor board I bought with B15 was dead. When I added the daughter board to my non-B15 Pentium processor, and swapped hard drives and it works. Now I need to figure out how to swap cal data and serial number.

BTW, let me know if anyone needs a image. Firmware 4.0 w/MSNT seems impossible to find. I also have images of 3.2 and 2.1.

Thanks for the help all.

Hi Sbvr4

I have a ZVR with Bios 3.3 which run a Windows NT 4.0. However, unfortunately the HDD has died

I would be interested in the 4.0 Firmware with or without the instrument drivers (ZVR drivers are still available for download).
Thank you in advance

Andreas

Hopefully you got your ZVR up and running Andreas

Yes, it works again.
Turns out the CF replacement card was at fault

Hey you folks!
I've got a ZVK network analyzer that won't boot, and looking through your thread on the FSEA I notice that the CPU board looks exactly the same.
Couple questions:
- my unit doesn't do anything at power on. Nothing on the screen or on either VGA port, no beeps, no blinking lights on the Floppy. All the power supply lines are good and flat and in spec. Anybody solve this kind of problem?
- If my CPU board is dead, where can I find a replacement? Some place in Germany?

Thanks in advance!

Hi all,

This very first message to try to answer the last post (I will later make a more complete post about the repair of a FSIQ3 unit that we had at work).
On the FSIQ that I did repair, the CPU board was also faulty (same behaviour as paul above. Power up but screen stays black and nothing else).
After some long 'reverse' of the board, I found that there's a small PIC16 microcontroller underneath the HDD (you must remove the drive and caddy). Long story short, This PIC16C has a 4MHz resonator that was dead on my board. I replaced it with a new resonator and the unit started again (more details in the post I will do to share all the things I collected during this repair).

I hope yours has the same fault (to ensure, simply sold a wire to the resonator pin next to the LT1431 SO8 chip, close to the PIC16C, and hook a scope. If there's only a flat 2.5V, then the resonator is dead).

Regards, Jerome

P.S : I'm trying to find a way to enter BIOS, does anyone succed doing this ?

Hi Jerome,
Nice bit of detective work finding that bad crystal! I had tried swapping the pentium, the memory, and checked all the voltages, but no digging like that. But then I happened upon a cpu board on ebay that fixed it. See my post here: https://www.eevblog.com/forum/testgear/rohde-schwarz-zvk-network-analyzer-wont-boot/msg3117922/#msg3117922
I'm tempted to look at that crystal but I think I'll wait until something else forces me to open up that unit. I was not able to get into the BIOS either.

hello, I ask for help, I have a rohde & schwarz fsea 30, I would like to replace the hard disk because it causes problems, I cannot access the bios screen, I read in the forums that the procedure to access is: connect a keyboard and start repeatedly click the DEL key on the keyboard, but it remains still at the booting screen but does not access the bios. I ask for your help, thank you and goodbye

analogRF · « **Reply #83 on:** January 19, 2021, 01:49:07 am »

I am not 100% sure about this but I believe you can only access the BIOS if you have option B15. They call it computer option or controller option.
That gives you a "separate" VGA output that does not show the SA screen but instead you get a WinNT or DOS computer screen.

analogRF · « **Reply #84 on:** January 19, 2021, 03:21:24 am »

why do you need to access BIOS anyways?
I replaced my HDD with CF card and never needed to access bios.

All,
For anyone interested in a solution in removing the old 2.5 HDD, I can confirm these will work even with older DOS 2.1 version. Best part is you aren't limited to HDD size. Mine booted just fine with a 256GB micro SD card. Ironically, its slower to boot with this conversion (even with a 2GB SD card) than the old 2.5 HDD. I'd recommend buying the card and 3D printed mount. Makes install easy. No affiliation with seller, just have personal experience and can vouch that it worked well.

I am very interested on the details and the long story.

Is there a chance that FSEA image will work on a FSEM30 ??
I have a rather disturbing problem on my unit; Its working all fine from 0 to 26.5 GHz but somehow some options are disabled or replaced by the EMI RECEIVER mode. Plus the I\Q CAL does not save the cal data on the disk because of that(I believe). Before it was doing just fine, I just added some Firmware options and somehow one of them got stuck at some eeprom memory address and wont go away

YetAnotherTechie · « **Reply #88 on:** July 05, 2021, 09:03:04 am »

I have some fsem firmware, i'm not sure if it's also for the unit you have which is latter than mine. I can only get it in a couple of weeks, and i don't know were it is, but i need to get it anyway, so when i do i'll let you know.

Extrasolar · « **Reply #89 on:** July 05, 2021, 08:13:55 pm »

Thanks for the response. I will really appreciate it if you send me a FSEM image, it makes no difference if it is FSEM20 or 30, should work nonetheless.
Hopefully will restore the Spectrum Analyzer ...
Thanks again and kind regards !!

Hello you all,

I hope someone can help me with my problem.

A friend of mine had 2 FSEA 30 analyzers, an old one (version 1.63) and a newer one (3.2).

The old one was still in use so we started with the newer one to upgrade the HDD to Compact Flash.
This went with no problem at all. cloned the HDD wrote it to the 2GB CF, mounted the CF with converter board in the analyzer and booted fine.

Now it was the turn for the old version.
cloned the HDD, wrote it to the 2GB CF card, mounted the CF with converter board in the analyzer and nothing. okay, changed the converter board, nothing... changed the CF card ... nothing.
The analyzer still booting fine fron the original HDD.

Can someone help me out with this problem ??

It looks like the older bios version has no auto HDD detection or something like that.

Ik hope someone can take a moment to answer my question, the HDD is making more noise every day, R&S can't help with this problem anymore and I'm afraid the HDD can stop at any moment now.

YetAnotherTechie · « **Reply #93 on:** September 21, 2021, 04:15:45 pm »

Are you using industrial CF cards?

paul@yahrprobert.com · « **Reply #94 on:** September 22, 2021, 05:18:49 pm »

hi,
On my ZVK I replaced the HDD with a SD card solution, see this post:
https://www.eevblog.com/forum/testgear/rohde-schwarz-zvk-network-analyzer-wont-boot/msg3117922/#msg3117922
Not sure it would work for you but its pretty cheap to try.

I have a Rohde&S FSEM30 20 Hz-26.5 GHz. Unfortunately, it has a completely damaged HDD and I have been unable to extract information from it.
If possible, could you re-upload the disk image that you suggested in August 14, 2021?
Thanks and kind regards!

Please post if it works, original disk has 3 partitions, i don't know if this set recreates them. Did you try DDRescue? disk is 6GB but only aprox 25MB used.

No, I did not use ddrescue, my HDD failed catastrophically(
