TSCM TEMPEST
RF attenuation meter
- wanted item
- this page is a stub
MF-130D was a portable RF Leak Detector/Attenuation Meter Kit, introduced
around 2001 by ETS-Lindgren in Eura (Finland)
as the successor to the analogue 4F-130.
It is intended for testing the performance of EMC shielding enclosures,
such as the RF-shielded rooms inside embassies that are used for
confidential conversations.
The 4F-130 can be used as a countermeasures device (TSCM)
as well as TEMPEST certification tool.
Around 2010 it was successed by the MF-9F.

The diagram below shows the positioning of receiver and transmitter
for each of the measuring standards. The transmitter is always
placed outside the enclosure, whilst the receiver is inside. With the
military standard MIL-STD-285, the transmitter and receiver are placed
in a horizontal plane with the antennas facing each other. This is known
as coplanar or in-line orientation.
With the NSA 65-6 standard, transmitter and receiver are placed
vertically with the antennas in parallel on a common axle, as shown in
the lower part of the diagram. This is known as coaxial or
parallel orientation. It is believed that the NSA method provides
more coupling between the transmission and reception antennas, and
therefore offers a better indication of leakage.
For both standards, the transmission and reception antennas should be
held 30 cm from the RF-shielded wall. The removable measurement rods
can be used to measure this distance accurately. Any contact between
the measuring rod and the metal shielding of the wall should be avoided.
Calibration is done in free space, with a gap between the tips of the
measuring rods that is equal to the thickness of the RF shielded
enclosure under test – as shown in the diagram above – and clicking
the MODE button on the receiver. The devices can be placed
on tripods for more stability.
