Analog Oscilloscope
Is a measurement apparatus capable of visually depicting regular changes in electrical activity, such as an electrical current or signal. The resulting data appears as a waveform drawn on a graph with two axes, where the horizontal X axis represents time and the vertical Y axis indicates voltage. In addition, the luminance of the waveform itself is often referred to as the Z axis, which demonstrates the intensity of the activity measured.

1mV-300V / 2 CH. Milli-Voltmeter
Digital MVT-172D
Is applicable to measure RMS value of sine wave with frequency range 5Hz~2Mz and voltage range 100μV~300V. This instrument has a 4 digit display with high precision, small frequency effected errors and high input impedance. There are three display ways including voltage, dB and dBm, supplying a clear and intuitive display. Auto measuring range switching makes your usage more convenient. All switches are touch switches with high quality, providing good hand feeling and high reliability.
