TEMP 8400, 9 kHz - 1 GHz,Tempest AMN (LISN)

The symmetrical AC-network TEMP 8400 consists of two identical channels for the lines "A" and "B".

It is constructed with air-core inductors, in order to avoid intermodulation interference. For the evaluation of interference phenomena, the unsymmetrical interference voltage of a conductor to ground reference in the frequency range of 9 kHz to 1 GHz can be measured. Lower-frequency interference that may cause damage to the measuring receiver input shall be mitigated by additional high-pass filters.

Application

The N-terminals "A" and "B" represent the reference plane for high-frequency measurements on the EUT-side of the TEMP 8400. For the connection of the EUT, the N-terminals are annoying. Therefore the adapter TEMP 8401 wing connectors / N male connectors must be attached to the connectors "A" and "B" of the front panel.

The EUT is connected to the wing terminals of the adapter. The power supply or mains (AC) connectors are at the backside of the TEMP 8400 (AE port). The wing terminals are not removable, so hook type cable lugs or 4 mm laboratory plugs can be used for contacting. More adapters are available i.e. TEMP 8401 GB - N to BS1363 (British type G connector) or TEMP 8401 DE - N to CEE 7/3 (Schuko). The maximum allowed continuous current of the EuT is 16 A. The voltage drop is approximately 22 V at 50 Hz and 25 °C. For a short time 25 A may be drawn. The temperature of the integrated inductors must not exceed 150° C when currents higher than 16 A are drawn.
