ETS-Lindgren's MF-9F Series of RF Leak Detector/Attenuation Meter Kits are designed to simplify the performance evaluation of shielding enclosures. These kits offer the ability to make measurements for military and commercial standards. The receiver module can store up to 63 attenuation levels per frequency to be downloaded to a PC. Windows compatible software is included for viewing, processing, and printing data.

The Model MF-9F-LF is intended for testing at lower frequencies: 10 kHz, 156 kHz, 1 MHz, 10 MHz. The Model MF-9F-HF is intended for testing at higher frequencies: 8 MHz, 16 MHz, 32 MHz, 64 MHz. The Model MF-9F-VHF is intended for testing at a 128 MHz frequency.

All transmitters and receivers feature backlit LCD displays, easy-to-use keypads, and rechargeable NiMh batteries. The receiver's LCD display frequency, attenuation level and battery condition. The keypad can be used to select MIL-STD or EN testing, and to set an attenuation threshold level for activating an audio alarm. The receiver also has USB port to download data to a PC. The transmitter LCD displays frequency and battery condition.

For testing per NSA 65-6/IEEE STD- 299/EN 50147-1, the receiver is placed inside the enclosure, at a point opposite the transmitter located outside of the enclosure. Included spacers maintain correct distance of the receiver and transmitter and the shield barrier. The attenuation can now be read on the receiver's LCD and stored in memory for later downloading.

For testing per MIL-STD-285, the receiver is placed inside the enclosure, at a point opposite the transmitter located outside of the enclosure. Included spacers maintain correct distance of the receiver and transmitter and the shield barrier. Place the transmitter and receiver in vertical orientation to each other to attain the minimum attenuation value. The attenuation can be read on the receiver's LCD and stored in memory for later downloading.
