Advantage of the NNBM 8124 Series 

All Automotive Standards have differences in specifications.

As a result, most LISN’s are designed for only one standard.

The NNBM 8124 series was designed with a specifications broad enough to meet the requirements of 7 standards.

Example:

Impedance requirement of CISPR 16 goes asymptotically to 50 Ohm while CISPR 25 limit goes towards 47.6 Ohm, both with 20% allowed tolerance. ISO 7637-2 has only 10% tolerance. If you overlay all these standards’ limits there is only a very small range of overlap. The 8124 series fulfills all these standards.

Other Advantages

· Built in switchable termination of 50 Ohm can be loaded with up to 100 Watt (data sheet says only 50W but they are built much stronger). This is useful for Bulk Current Injection or immunity testing.

· Automatically grounded by its metal feet when set up on metal table.

· Calibration adapters automatically available in all major calibration labs world wide.

· Upgradeable to DO-160. The NNBM 8124 or NNBM 8124-200 can be upgraded to DO-160 with a 10 uF capacitor (CAP 10-100 or CAP 10-200) and a CAL DO-160

 

BNC Connector
This connector has many advantages: easy to disconnect and connect. You know when the connector locks it snaps. Like the N Type the BNC is hard to damage. The BNC comes in three flavors. Standard 50 Ohm, 75 Ohm and reverse polarity connector. It is a great Snap-On connector. The BNC’s are usually limited to DC to 4 GHz and it can snap off just as easy as it snaps on. If you are in a high vibration environment the BNC may not be suitable. High power High EMI issues the BNC is known to leak RF. The good ones will be –55dB to 3GHz the lesser ones can be as low as –25dB and even lower if a poorly shielded cable is attracted.

 

N Connector 
The N-type is a thread on connector with a long neck. This provides excellent EMI protection. In many cases > –90 dB for RF leakage which is dependent on the manufacturer and cable type.
The N-type comes in 4 flavors. The standard 50 Ohm, the 75 ohm, the reverse polarity and the 18 GHz version.
Most basic models go to 11 GHz and most high frequency versions go to 18 GHz. The N Type is better in higher voltage 2500 Vrms at 50Hz for most N-Connector types vs. 500Vrms for the BNC-connector types.

The differences between the two connectors are the Vrms and the frequency response.

Schwarzbeck TSC 7042 Toyota Single Path Low-Impedance AMN Automotive LISN 

The main application of the unsymmetrical single path AMN (artificial mains network) Toyota LISN is the measurement of interference voltages in the frequency range from 10 kHz to 150 MHz for automotive purposes according to Toyota standard TSC7042G.

 

An external coil has to be connected to the terminals K1 and K2 (Fig. 1). The inductance of L2 should be adjusted so that the total inductance of L2 and the connected cable (terminal P to EUT) equals 0.5 μH.

Fig. 1. Principle circuit diagram of the TSC 7042 Toyota LISN

 

Interference voltage measurements

The device under test has to be connected to the terminal P at the front panel. The supply voltage has to be connected at the back panel. The 100 μF capacitor located at the backside is connected to ground. The RF-interference voltage emitted by the equipment under test can be measured at the N-connector using an EMI receiver.

Please note: The injected RF-power passes from the EUT-terminals directly to the N connector without any attenuation. Eventually connected RF-measuring equipment may be damaged!

The device under test may drain a continuous current of 70 A and for a short period of time it may even drain more than 100 A.

A sufficient air-circulation must be provided to avoid overheating of the LISN.

Do not cover the LISN! The top and bottom hole-plates must not be covered to provide good air circulation.

 

Impedance at EUT-Terminals (Calibration Adapter KA 8125 required), L2=0.5 μH, BNC-Port terminated with 50 Ω, mains terminals shorted

Voltage division factor EUT-Terminals to N-connector (adapter required) L2=0.5 μH
