Re: LISN Calibration

Dear John, Thank you so much for teaching me. I will keep your suggestion (fix a training session with Agilent) on my wish list. I did browse Agilent's training courses yesterday. Due to the current ecomonic downturn, it is not easy to obtain an approval for an out of state training. Instead

Re: LISN Calibration

I ran into that exact problem (a floating power source) a few years ago. The conducted emissions test results on a power supply at an outside lab were 4-5dB higher than our precompliance bench in-house. I sent the LISN's back to the manufacturer for performance verification, and they were fine.

RE: LISN Calibration

Joe, For piece of mind. The LISN provides repeatable results for different line impedances. Making sure that the LISN impedance is what it is supposed to be and the insertion loss is satisfactory will give you a better comfort level when going to the test house. If you have not already done so

Re: LISN Calibration

I would say that if it came calibrated from the manufacturer and has not suffered visible damage it should be okay. It is easy to check a few spot frequencies or use a spectrum analyzer with tracking generator or separate sweeping sig gen to check performance. Either way it is not a big deal. o
