    Maximum voltage generated by a function generator

    Hello, I have a very basic question (since I am not familiar with generators !). I would like to buy an arbitrary function generator (like Agilent 33210A). In the data sheet of this generator its written that the generated voltage is 10 Vpp for 50 ohm charge résistance. So, I want to know if I...

    Techniques for testing PCBs in temperature chambers

    Dear all, I would like to know if someone has an experience with testing PCBs in temperature chambers following the production stage. In fact, we have to check 200-300 PCBs in 3 differents temperature : -40°C, 20°C and 60 °C. In our company, we have a temperature chamber allowing to acheive...

    RC oscillator and Quartz frequencies

    Dear all, I have a microcontroller for which I use a quartz crystal, and an RC oscillator circuit, both to produce an axact time measurement. My quartz has a frequncy of around 32 KHZ and my RC oscillator around 33 KHZ. I have a question regarding to the choice of my RC oscillator: - before I...

    Effect of parasit capacitor at the input of my digital circuit

    Dear all, I have a digital circuit (ASIC) designed for some specific purpuses. The circuit works well in most cases. However sometimes, it does not work i.e. I dont see any output. I am investigating if this problem could be related to parasit capacitor at the input of my circuit. The input of...

    Capacitor discharges rapidly

    Dear all, I have a very strange problem. I have the following circuit (picture attached): The circuit receives discrete pulses with 7.5 V amplitude and 2.5 A of current over 1-2 ms. The voltage is then stabilzed by a zener voltage at around 5.6 V. Then the capacitor of 150 uF will store the...

    What could be the failure cause of a circuit when it works 18 times over 20 times

    Dear all, I have a big problem which makes me crazy!! I have a circuit containing three blocks : - block 1: RC parallel circuit - block 2: Asics circuit - block 3: two transisitors (1 bipolar and 1 mosfet P type) The main job of the circuit is to receive a single rectangular pulse at the input...

    Effect of mechanical shock on Tantalum capacitors

    Hello, I have a circuit with a tantalum capacitor Inside. The capacitor is connected in parallel to a DC generator (a coil and a magnet). The generator charges the capacitor correctly. For some reasons I should provide high linear acceleration to my circuits (something like 80'000 m/S2)...
