EM TEST
6.4.8.
Verification on coaxial output
Verification Setup with 1000 load
Procedure of verification
-
Switch on the EFT 500Nx
Disconnect the line power from the EUT supply input at the rear of the EFT 500Nx
-
Set the input impedance of the oscilloscope to 50
-
Select Quick Start mode and set the following parameters under Change for further operation.
-

Perform the verification by the following steps
-
1. 1000 loaded condition (KW1000)
For verification connect the oscilloscope via the 1000:1 high impedance attenuator KW1000 to the coaxial
output of the EFT 500Nx and measure as specified. Set the oscilloscope to the 50 input impedance mode.
2. Measure the rise time tr, pulse width td and the peak voltage.
