I managed to get it sent to me by FNIRSI, and in this video I'll perform some dedicated measurements to verify the bandwidth and its interesting features, such as the ability to generate Bode plots up to 50 MHz and the production of spectral analysis with 3D visualization and waterfall. I don't want to reveal anything; I've formed my own opinion, and you can form your own from the images. In the first part of the video, I use Bode plots to examine the frequency response of various passive components, such as a carbon resistor, a wirewound resistor, a 230V mains filter, a ceramic filter, and an intermediate frequency. This device is very useful for identifying the frequency response of passive components up to 50 MHz. In the second part, I test the oscilloscope's bandwidth with various measurement setups, using a 50-ohm matched coaxial cable, the supplied probe, and the matched probe with high-frequency probing. We'll discover the specific signal processing this oscilloscope performs above a certain frequency. ⏰ Index: 0:00 Prologue and Theme 1:30 Introduction 4:00 Unboxing and Specifications 7:55 Boot Time and Function Explanation 10:20 Bode Plot for Carbon Resistors 14:10 Bode Plot for Wirewound Resistors 15:50 Bode Plot for Loudspeaker 10:20 Bode Plot for Mains Filter 21:50 Bode Plot for Ceramic Filter 24:10 Mid-Frequency Bode Plot 25:00 Bandwidth Measurement with 50 Ohm Matching 29:00 Bandwidth Measurement with Supplied Probe 32:00 Bandwidth Measurement with Probe and HF Probing 33:20 FFT, 3D, and Waterfall Analysis #repairs #electronics #amplifiers #lab #tools #oscilloscopes #tutorials #projects #tv #audio #pieraisa #electronicscientists
