Category: Meter Counter Circuits / Meters Circuits This circuit is also crossed to: Varius Circuits Views: 4425 Rank: 0 The vertical deflection amplifier uses a 180 degree phase splitter to generate a differential signal. The CRT requires large drive voltages, but almost no current. The oscilloscope bandwidth is limited by the amplifier chain as almost all electrostatic CRTs have a bandwidth extending to several hundred megahertz. visit page. 
Related circuits Buzz box continuity and coil checker Differences between shorts, coils, and a few ohms of resitance The tracer detects the weak magnetic field of any current-carrying house wiring and amplifies this signal to a level that is adequate for driving a magnetic earpiece. Fast Video Signal Amplitude Measurer Circuit Video-signal amplitude can be measured with this simple circuit, which is basically a modified standard peak detector. The device can verify RGB generated by video RAMDACs. Ul is a high-speed buffer and U2 is a latched comparator. CI is a hold capacitor. Reset is performed by Q3. U2 has a latch... The LED is normally lit, but it will be briefly extinguished if the input exceeds a preset (by RVl) level Current Source For Resistance Measurements Circuit Useful for low-resistance measurements, this 1-A current source will produce 1 A in unknown resistance Rx. For best results, R,c should be less than 1 to 2, because only 3 V are available. The design shown is a simple unit for QRP operation on all authorized frequencies up to 30 MHz. based on a toroidal transformer Tl. The secondary winding of Tl samples a small amount o1 rf power. both forward and reflected, which is divided by the bridge circuit and rectified by diodes Dl and... This continuity checker (built around an LM339 quad comparator with open-collector outputs) eliminates false r DC-10Mhz Amplifier for Oscilloscope The DC-10 MHz amplifier shown below is identical for both scope channels. The input FET should be mounted directly on the adjustable attenuator switch for best frequency response. The vertical position pots, R27 and R51, change the dc level of the traces, but do not affect the ac signal. There is... Atari Star Wars on oscilloscope
