Line Impedance Stabilization Network

6.0. Calibration

Before calibration, to abvoid electric shock or damage to the instruments, power off the

instrument.

LN2-100A Calibration Jig (CA-002-LISN)

Calibration Jig Connection

LISN’s calibration has to meet the impedance curve specified in CISPR 16. Because it is needed

to get the same result even in changed places or repeated tests.

LISN needs the exclusive jig for calibration.

Output BNC for measuring is terminated with 50

resistor and measure separately L1 and L2.

For the detailed impedance measurement, sweep measuring is needed. Calibration at a few

frequency may not show all the characteristic of LISN.
