EMC Pre-Compliance Testing  
The GSP-9300 EMC Pretest function is a comprehensive suite for 
performing, debugging or estimating radiated or conducted 
emissions as well as the ability to troubleshoot immunity tests.  
The EMC Prestest function is divided into 5 main functions: EMI 
Test, EMI-M Probe, EMI-E Probe, Voltage Probe and EMS Test.  
The EMI Test function is used to perform radiated or conducted 
emissions tests. These tests include inbuilt support for a number of 
EN and FCC standards to test against. 
The EMI-M Probe functions allow you to simulate the radiated 
emissions at 3 meters and 10 meters for a number of different EN 
and FCC standards.  
The EMI-E Probe function is used to debug sources of 
electromagnetic emissions using the GW Instek EMI-E probes. This 
function also allows you test against EN or FCC radiated emission 
standards. 
The Voltage Probe function allows you to estimate the conducted 
the emissions from the power lines without having to perform 
conducted radiation tests with the increased cost of a LISN device. 
It can also be used to debug sources of conducted emissions on 
your DUT. 
The EMS Test function allows you to debug radiated 
immunity(susceptibility) weakness in the DUT by outputting a 
source signal from the TG Output with user-defined characteristics.
