VECTOR-GUN HANDHELD DIRECTION FINDING ANTENNA SYSTEM
HFDF
-
National RF's Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum. Due to the nature of a Faraday shielded loop, the antenna exhibits a sharp null through the diametric center of the loop. This null is used to determine the direction of incoming radio signals or to locate electrical noise being radiated from some source. The internal high gain amplifier is used to compensate for the inherent inefficiency of the actual loop at the operating frequency. Overall, the system dynamic response is about +6 dB as compared to the dynamic response of a dipole. To aid in the direction finding process on strong signals, an internal 30 DB attenuator is provided. As the loop antenna presents a bi-directional response, tri-angulation may be required to eliminate the ambiguous signal direction. The line of site of the incoming signal is determined by listening for a signal null on the receiver or by watching the receiver’s S-meter.

Vibration Unit Tester
BK2020B
-
We developed the BK2020B as an upgrade to our BK2020 to test the electrical specifications (RPM, current, drop pulse, start up voltage) of your cylindrical or coin type vibration units. You can also test vibration level, noise, isolation resistance, and the DC resistance. The DUT power supply and all measurement components are self contained, so external devices aren't needed and the tester uses DSP, making it capable of fast, highly accurate and reliable measurements. The BK2020B is very versatile. It can be set up as a stand alone machine, or used with a PC and software for access to more information, and to save the data for analysis. Either version is great on the product line but you may also use it for QA, QC and development.

-
The 40-830 is a 75 RF Switch available with 3 or 6 separate SPDT relays in a single PXI slot. Both versions have been designed to exhibit low insertion loss and VSWR through the use of modern RF relay technology at an affordable cost. The switch banks have been carefully designed to ensure excellent and repeatable RF characteristics to frequencies of 3GHz with each path having a nominally equal insertion loss. The design of the 40-830 minimizes the injection of noise and unwanted signals into the signal path by careful attention to the mechanical and electrical design.
