    How to sweep test an IF filter

    http://youtu.be/psMss8DcuTw

    Also, don't forget to read the video description.
    I did this test on some IF filters I am currently selling at the time on eBay.
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

    The bandpass response of that filter looks terrible, probably because the filter was not set up before testing with correct source and load impedances.
    Is it plugged in?

      doesn't appear that the source and load impedances are matched.. what's the working impedance of that filter?

        How Can I test PWM DM0365R?
        by chth96
        Hello
        I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
        So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
        I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
        I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

        test active pfc power with lamp test
        by khelane
        Hello
        I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
        Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
        Is there a way...

        Mats / mods: detected and repaired GPU fault. Cant seem to test after!
        by chronic519
        Hello.

        GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
        Found issue with a RAM block
        Replaced, green lines gone.
        Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
        Used a good card to test and same results low errors 32+.

        I am just search for some form of command to do a full test on the GPU.
        I just ran the mats command with my good GPU and passed after roughly 40 min.
        The repaired one, ran...

        Yamaha 2064 No sound but Test audio working
        by hemant_2222
        Hello Guys,

        Greetings!

        Hope you all are doing well.

        I am looking for suggestion on Yamaha 2064. The problem with this receiver is that it has no sound however when the test tones are activated it does outputs from all the speakers. It is working in two channel stereo mode but when you select other sound modes, it doesn't. The last time it had a problem, I had replaced the DAC
        PCM1681DBQR - IC263 and it worked fine.

        Other issue with it is one of the STK ICs is getting more heated then the other one but that can be looked at later.

        Modding HPF filter
        by madan1
        Hi everyone.
        Recently scored a dead amp from a mackie srm1801 subwoofer and after fixing it, now I'm thinking about a home cinema/party subwoofer project.
        Most likely I will use a 15" JBL woofer, which I already have and a diy box.

        After reading the mackie user manual, I noticed that it has a 40hz HPF (labeled as "36Hz BUTTERWORTH HPF" in the SM) to protect the speaker from low frequencies. Indeed this seems to be good idea for the intended usage - professional music subwoofer, but bad for movies, where one would expect to "feel" the SUBwoofer....
