Fully operational, at last! WTI anechoic chamber rental & EMI countermeasure verification services

Hello, everyone. I’m Akatani and I’m a manager for anechoic chamber rental and EMI test & solution service.

Now, let me tell you a little bit about our equipment that you’ve been waiting for.






The two pieces of equipment in the front are line impedance stabilization network (LISN) and the one on the left is a popular type called V-LISN. The one on the right is called Δ-LISN, which can measure a common mode noise and normal mode noise independently. By using Δ-LISN, you can efficiently perform EMI suppression measures.

The antenna behind them is a horn antenna, which can measure 1 to 6 GHz.


This is a loop antenna for the frequency range from 9 kHz to 30 MHz.


This is a hybrid antenna that can measure from 30 MHz to 1 GHz in a single unit.
Using two antennas like a bi-conical antenna and a logarithmic periodic antenna, especially in the phase of EMI suppression measures, makes measurement of this often evaluated frequency band quite troublesome because you have to exchange the antennas. If you are an engineer who usually struggles with EMI suppression, I’m sure you can agree with me.


This is a comb generator that produces signals ranging from 150 kHz to 1 GHz in periodic frequency set beforehand. By using this, we perform the system checkup as daily inspection. It can also be used to confirm a correlation with your or a certified body’s anechoic chamber and WTI’s one. We also have a comb generator for 1 to 6 GHz.

Everything is ready to go. All that’s left is customers use.

Customers who visited our anechoic chamber tour said:

“I didn’t know there is such facility nearby”
“Our anechoic chamber is fully booked up until next month. How about yours?”
“The Electromagnetic Field Visualization System seems good, but can I use this one too?” (Yes, of course)
