it measures AC/DC voltage, Current, Continuity, Resistance, Frequency, Capacitance
it measures AC/DC voltage, Current, Continuity, Resistance, Frequency, Capacitance it has a basic dc accuracy 0.5%, CAT III 600 V safety rated, diode and continuity test with buzzer, small lightweight design for one-handed use, rugged, durable design, and automatic shutdown

I used it for checking the continuity of the traces by rotating the nob to the Ohm fuction which have mutiple testing modes like finding resistence, to checking wether a diode is working or not, and finally checking continuity we need to press the yellow button on the right side to navigate through these options.

### UNISOURCE DS-1100 100 MHZ, 2 CH, Digital Storage Oscilloscope
<img class="zoomD" src="../../images/photo_2022-03-09_19-15-47 (2).jpg" alt="osciloscope.jpg" style="width:70%;">
The digital storage oscilloscope is an instrument which gives the storage of a digital waveform or the digital copy of the waveform. It allows us to store the signal or the waveform in the digital format, and in the digital memory also it allows us to do the digital signal processing techniques over that signal. The maximum frequency measured on the digital signal oscilloscope depends upon two things they are: sampling rate of the scope and the nature of the converter. The traces in DSO are bright, highly defined, and displayed within seconds. it have 100 MHz bandwidth, 1 M Memory, USB storage, RS232C & J45 interface,4000 point record length for each channel,Multi-waveforms math, FFT Function, Cursor & Track measurement, Waveform Record & Recall, Trigger Mode for Edge, Video, Pulse Width, Slope & Alternate

we can find the speed of the board/program by checking the signals using oscilloscope upload a program to the board wich turns a pin high and low without any delay

### INSTEK AFG-2100/2000 SERIES ARBITRARY FUNCTION GENERATOR
<img class="zoomD" src="../../images/photo_2022-03-09_19-15-47.jpg" alt="function gen.jpg" style="width:70%;">
A function generator is a specific form of signal generator that is able to generate waveforms with common shapes. Unlike RF generators and some others that only create sine waves, the function generator is able to create repetitive waveforms with a number of common shapes. The AFG-2100/2000 Series Arbitrary Function Generator is a DDS (Direct Digital Synthesized) based signal generator designed to accommodate the Educational and Basic Industrial requirements for an accurate and affordable signal source covering the output of Sine, Square (Pulse), Ramp (Triangle), Noise and Arbitrary waveforms.it have 0.1Hz to 25MHz with in 0.1Hz Resolution, Sine, Square, Triangular, Noise and, Arbitrary Waveform, 1% ~ 99% adjustable duty cycle for Square Waveform, Waveform Parameter Setting Through Numeric Keypad Entry & Knob Selection, Amplitude, DC Offset and Other Key Setting Information Shown on the 3.5" LCD Screen Simultaneously, AM/FM/FSK Modulation, Sweep, and Frequency Counter Functions (AFG-2100 only), PC Arbitrary Waveform Editing Software
