I continued to check on the fault and got a little further: I checked the analog switches and cannot make any sense of the way they are controlled. But the signal BPW on the more modern schematic is

Hi, Ray ELGY, EI3DQB here. I had a working 4015 before the psu developed a fault. Unfortunately the diagrams I have are nothing like the installed psu which I understand was made by a sub contractor.

Okay, I reply to myself about how the fault finding proceeds. The schematics I have are for a board revision 06 but my board is rev. 03. Reverting to the original 1.41 firmware and the fault stays the

Hi! For many years I had a 4015 lying around with lots of errors, broken PSU and non working keys. End of last year I pulled all parts from the different shelfs and ESD packaging and went through by

Sorry for replying late, but I was on the 4 day training... Yes, I know the FEX + Duplex arrangement, I have one unit with FEX working and a prototype unit with some strange modifications on that

Hi Ulrich, I have an extender card, but do not have any service s/w. The s/w may be the trick to calibrate any small signal path error, similar to the IFR COM120! The Duplex + FEX unit combined with

Hi Gerald! Do you have any service adapters? Do you have the Extended Service Software SRAM Card? Or could you open the Duplex, Output and FEX unit, leave the unit on the side with a good look into

Hi All, The 4032 I have been working on has developed a Duplex +FEX failed self test, however all TX/RX functions are fine to 2300 MHz. It does not fail self test at initial power up, after power up

Hi Tom! Getting to the front-panel is pretty easy, just you need to detach the ribbon cable led under the blue cover of the side of the unit. The you can remove the PCBs from the panel. Find the

Hi all, (cross posted from the W&G group) recently I repaired a W&G SNA1, spectrum network analyzer 100-180MHz. It had a broken through-cap (Durchführungskondensator) and one of the large caps in the

I have a Stabilock 4032 with a burned out power switch lamp. ?Does anyone know how hard it is to change out the switch? ?I have a diner machine so the part is not a problem. Thanks Tom

Now sold.

Great! Just email me directly when you have time then we can try to combine what we have and get something organized and put online. I am ready. But it should be possible to get in contact with "old"

Oh, I wonder if that chart really exists... I talked to a field service tech of Schlumberger and he told me, that he made his own charts of working firmware combinations to help out his customers. But

Yes. And it would be nice to have a compatibility chart from Schlumberger/Wavetek with corresponding SW and HW versions. The software can be upgraded to latest versions for the specific HW, but we

The EPROMS would be very fine to have but unfortunately with Stabilock the EPROMs very closely connect to PAL and PCB revisions. And the required matching revisions are across the PCBs! So if you use

EI3DQB. Ray Elgy. I have some manuals & a spare 4031 for spares. Power supply is missing. The one I was using packed up with a fault in the power supply. Problem is it is nothing like the manual. It

I'm selling off my interest in Wavetek/Stabilock, as I'm busy enough with other projects. This SI4015 seems to have a power supply problem, as it had many shorted 1000uF 40V caps in supply. It did

Hi Peter, The Australian BMARC radio club has a 4031 donated by Mark Williams. A user manual perhaps. Keep up the good work. Alan VK2ZIW On Wed, 01 Nov 2023 05:08:41 -0700, Peter Andersen wrote

Hi all I am reading all eproms from the 4031/4032 Stabilock's I have in my lab and I am going to make a page with info, manuals, eproms, pictures etc. on my website: https://peel.dk/Stabilock/ If
