#How to use a test tone generator with an oscilloscope generator
Set the controls of the function generator to produce a sine wave of about 1000 Hz frequency and a few volts amplitude. The Oscilloscope : 'An oscilloscope, previously called an oscillograph, is a type of electronic test instrument that allows observation of constantly varying signal voltages. After switching off and removing the test resistance, the reading of the decade box settings or measuring the variable resistor with an Ohm meter gives the value equivalent to the input impedance of the amplifier. Use the BNC cables to connect the main' output of the generator to CH1 of the oscilloscope and the aux' (or sync' or TTL') output to CH2. At this setting the signal is shared equally between the test resistance and the input impedance of the amplifier, meaning that the resistance and impedance are equal. The resistance at the amplifier input should then be increased until the output waveform is exactly half its previously set value. The display on the oscilloscope screen should be as large as is practical and set so that its amplitude and half its amplitude can be easily estimated. It includes waveform examples, to help the operator best adjust the transmitter and amplifier. The waveforms created by a function generator are observed using.

Theyre incredibly handy when learning how to diagnose and test problems with electrical equipment. Function Generators are used to create different types of electrical waveforms. The amplitude of the input signal should be adjusted so that the display on the oscilloscope is noise free (large enough) and distortion free (not too large). This appnote explains how to use a Two Tone Test generator to make amplifier distortion measurements with an oscilloscope. PicBerry is a Digital Oscilloscope and Function Generator created by students at Cornell University.
#How to use a test tone generator with an oscilloscope series
Using a simple circuit where a capacitor is in series with a resistor we can slowly charge a capacitor and measure the voltage across it using an oscilloscope. To determine the capacitance we will measure the time that it charges to a specific voltage. The signal generator is set to provide a sine wave output at 1kHz. In this blog I will show how to measure the real value by using a scope. An oscilloscope or AC voltmeter is connected across the amplifier load (e.g. The oscilloscope is a particularly useful item of test equipment that can be used for testing and fault-finding a variety of electronics circuits from logic circuits through analogue circuits to radio circuits. A variable resistor or a decade resistance box is connected between the signal generator and the amplifier input and its resistance is set to zero Ohms. The set up for measuring input impedance is illustrated in Fig.
