Standard Gain Horns
-
Standard gain horns can be used to experimentally determine the gain of other antennas by using the substitution method. The standard gain horn and the antenna under test are alternately connected to a well matched detector system in order to compare their relative power levels. The power level difference is then added to the appropriate level of the calibration curve to determine the absolute gain of the antenna under test.View more Standard Gain Horn Antennas

High Frequency Current Transformer
HFCT Ø 140mm
-
Techimp Clamp High Frequency Current Transformer model 140 is an inductive sensor for partial discharge measurements. It is suitable for online /off line PD tests on : large diameter cables ; grounding rod bar ; etc. A TNC termination is available to connect the Clamp HFCT 140 to the TechImp PD analyzer : PDCheck , PDBase etc. The arrow indicates the requested input current (Iin) direction to get coherent output voltage (Vout) polarity respect to ground. When the sensor is installed with the arrow directed to ground, the detected voltage signal (Vout) has the same phase of the input current (Iin).

Becker Nachrichtentechnik GmbH
Modern receivers for broadcast have a large number of antenna inputs for the different radio bands. The devices of the FDMX series can be used to supply the antenna inputs with RF signals. The devices of the FDMX series splits a sum signal in frequency division multiplex into the individual broadcast bands and the L1 satellite navigation band (GNSS). Additionally, DC loads are provided for each antenna input to simulate active antennas. The presence of remote power supply is indicated by an LED on the units.
