GW Instek GLN-5040A Line Impedance Stabilization Network (LISN) Upgrade option for GSP-Series

The GLN-5040A accessory is used for EMI testing.
It provides a 'stable impedance for the EUT terminals and reference ground in the 'conducted emission range. It is able to isolate unwanted mains signals from the power supply and couples only the noise voltage of the measured device to the receiver. Product performance is in accordance with the standard requirements of CISPR16-1-2 for V networks with an impedance of 50μH + 5 Ω) || 50 Ω in the
frequency range of 9 kHz to 30 MHz.

It uses a standard BNC output connector with a 50 Ω impedance output to fit any measurement device such as receivers and spectrum analyzers.
