## Description

## Product Overview

![](https://www.limpkin.fr/public/sc_ampl_non_isol/sc_ampl_non_isol_diagram.png "")  
This board has been designed with side channel attack measurements in mind.  
It can provide 3 different voltages (3V3, 1V8 or 1V2) to your target and outputs the target current consumption to an SMA connector.  
A potentiometer allows you to vary the inline resistance, another one allows you to **change the overall current to voltage gain**.

## Frequency Response  

The platform frequency response for different shunt and gain potentiometers positions can be seen below.  
From DC to 50MHz:

From DC to 1GHz:

As you can see, **high frequencies get amplified the most**, which will actually be beneficial in an attack measurement setup as wires attenuate high frequencies.  
The above measurements were made using 20dB of external attenuation and a 45R series resistance, so the maximum current-voltage gain the platform can offer is **54dB or 500x**.

## Power Supply Setup  

In side channel attacks, **noise is your enemy**.  
The whole board therefore requires **4x 18650 cells**, and includes battery protection circuitry.

## Measurement Setup Advices  

When performing side channel attacks the following rules should be followed:  
- eliminate any wires you may have, or keep them as short as possible  
- keep in mind that any connection may bring noise to your output  
- perform an FFT of your output with the platform off  
- make sure your output isn't saturated  
- make sure your trigger is repeatable
