    Remote Control PA1000

    Hello together, I am trying to connect remotely Tektronix power analyzer PA1000. There are measurment i need to read but one not. For example i can read from power analyzer desired values such as voltage, pf, current, amps harmonics, which i can set to be even or odd, up to which harmonics...

    Folks i need some schematic for metal detector...

    If it has 5 pins connector i suppose that there are 2 ends of each coil and the 5th is GND, common etc. As i think there should be something like this: The coil with bigger numbers of turns should have more resistance and due to high frequencies from primary coil,the primary should have less...

    Folks i need some schematic for metal detector...

    Hello everybody, I can't find anything about mcCheck sx 3300profi metal detector, except the price of the device. I would appreciate any kind of help for this issue. The problem is that the detector's coil has been broken from the body and the person who tried to attach the coil, somehow...

    Problem with LT3092 current source

    I have decreased supply to 15V and when supply them from external power supply they dont stop working but when i connect them on transformer via voltage regulator on the same voltage (15.5V) current is decreasing, as it was before with greater voltage. Circuit is behaving different on 15V when...

    Problem with LT3092 current source

    There are 10 Lt3092's in group of two connected parallel so there are 5 separete output. Each group of them is acting almost similar. Definitely i should cool them more because one output dissipate about 5,6watts and they have thermal coefficient about 20 Cell/Watts so they get more then 100...

    Problem with LT3092 current source

    Yes it is heating up and it has no copper area or any heat sink. They are supplied with externall adjustable supply from 12V-36V, but they should work with permanent 36V. When 12 V is input Vout is 11.2v, Vin=36V Vout=35.something V. They should be able to generate 200mA but they have 185mA out...

    Problem with LT3092 current source

    Hi everyone, I am trying to get stabille em field in inductor so what i need is inductor and some current source to drive that inductor.The inductor is wounded and have cca 2000 turns, which in this case isn`t so important. Problem i have in this case is with current source.I need stabile and...

    Converting 5vdc to +/-2.5vdc???

    Hi guys I need this bipolar supply for ADC, and all i have of volatges is 5 volts. I dont wanna to use LM7660 for converting 5 to negative because i am confronting with 31 bits converter and i need very stabile supply.Positivie reference i made from REF02 but that IC have also +2.5v on its...
