The safer, easier way to pay online! GPS Monitor Kit for the Trimble Thunderbolt GPSDO. Now supports more instruments and Prologix GPIB adapters. Now you can put to good use these cheap ARM microcontroller boards! Keysight, Tektronix, Fluke and many others. QST, the publication of the ARRL. Electronic Circuit Design, software tools, Computer Audio tips and tools and a number of projects you can build. I frequent and more details about selected projects.

The unit was dead, when powering it on I could see a led blink on a front panel, but nothing else. It also turned out that someone already worked on my unit, many screws were missing, front panel was not fitted right to the frame and so on. ABSOLUTELY EVERY electrolytic capacitor in the PS leaked. MHz and many additional tones near the main were displayed. GHz PLL for the second mixer, that is used in lowest band only. I also fix broken screen cover, and assembly everything right. I already know that the circuit driving main YTO is faulty. GHz band drags the sweep signal down a bit. Last thing is burned out screen, it is still visible, but poorly. I have a 640×480 LCD panel with the right dimensions, but it is a bare panel. NT68676, this is the only controller that works with the strange synchronisms generated by the SA. Anyway did You used composite signal generated by the R3271 for display or something else? Yes, making a new power supply was not really easy, it took me a very long time. In the end I used the same signal for the CRT and through a buffer and some resistors I sent it to the RGB inputs of the LCD controller. The screen is now black and white but by varying the signal levels at the RGB inputs you can get any color. Anyway I am working now on a project that will use one of the lcd panels I have, so maybe after having fully working display with my own processor I will came back to the analyzer. If that turns out to be some strange passive element problem in a even more strange place I will get angry. YTO coil and that gave me an idea that adjustment is completely messed up on larger spans. Then I found an option in calibration menu that is not mentioned in service manual. I have the same unit, R3271A with tracking, working quite nice. The only issue I see is that amplitude reading is not as stable as it should. B it is so much as resoution is 0. Can anyone give me a suggestion? Im quite scared to unassemble the unit without a schematic. You can however check, before disassembling the entire SA and the power supply, if the various voltages have an excessive ripple which can cause the defect found. I will finish project then I will disassemble the analyzer. As per my experience it is a long way to complete. Do you know if your LCD kit replacement of CRT would work on an Advantest R3261 or R3361 spectrum analyzer serie ? R3361 SA so I cannot guarantee that it will work. IMHO it looks similar enough to try. But it does have a weird screen resolution. There are small lies, big lies and then there is what is on the screen of your oscilloscope. Pictures of my disassembly and repair work can be found at my w3afc. A couple days ago there was a smell like a blown electrolytic, and the unit shut off. It will actually start up but then shut down during boot. It was tested and verified fully functional before I bought it.
