Automotive Solutions
Over the years, we have acquired profound, specific expertise in a number of areas, especially with respect to RF assembly and antenna technology testing. To give an example, we have acted as general contractor for implementing a number of rotary indexing tables for testing and labelling antenna amplifiers. The implementation as a rotary table has a number of advantages, since all mounting and test processes, as well as the handling of defective parts, are interlocked and concatenated, thereby effectively eliminating possible error sources during these process steps.

Voltage Probe
KHZ43201
Beijing KeHuan Century EMC Technology Co,.LTD
The KHZ43201 voltage probe is a standard low resistance test probe, which meets the technical requirements for this product in the CISPR16-1 and CISPR14-1 test equipment. When measuring the interference voltage of the power grid, the artificial power supply network cannot be used at the load port, and sometimes it is necessary to use a voltage probe to measure the interference of the signal port, the load port, and the antenna port. The input impedance of the voltage probe to the ground wire is greater than 1.5KΩ, which can protect the input terminal of the receiver.

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

Ocean Signal RescueME PLB1 (Personal Locator Beacon)
RescueME PLB1
The RescueME PLB1 is the world's smallest 406mhz & GPS enabled PLBOperation of the rescueME PLB could not be simpler. To activate the PLB: Pull the retractable antenna out by its end tab, flip open the spring loaded cover over the activation button, hold the button for 1 second until the lights blink. Visual instructions are clearly printed on the case. When activated, the rescueME PLB1 will transmit accurate position data from its 66 channel GPS for a minimum of 24 hours while the integrated strobe light ensures maximum visibility.Ocean Signal has ensured that rescueME, like all of its other safety products, exceeds statutory requirements. RescueME PLB provides an incredible 7 year battery life, and is covered by a 7 year warranty. Even after more than 24 hours of continuous operation, and when the battery power is insufficient to transmit the satellite signal, the PLB1's homing beacon and strobe light will continue to operate. This high intensity strobe light features a molded lens to enhance the visibility of its efficient LED and it gives a powerful 1 candela light emission.Self-test of the PLB can be carried out with a simple button press with the start of test and results clearly indicated by a green flashing light. The antenna is easily extended like a normal tape measure and can be retracted using the winding mechanism on the top of the unit. This unique feature greatly facilitates user training and familiarization as it is not a one time deployable antenna similar to existing PLBs.rescueME comes with a snap-in mounting bracket and universal rubber mounting strap which can be fitted permanently or with each use. It is also supplied with a detachable flotation lanyard to accommodate all scenarios out of the box.

Active Monopole Antenna
AM-741
The 41 inch Monopole antenna is required for making electric field emission measurements below 60 MHz per Military standards (MIL-STD-461) and FAA (DO-160) specifications. This antenna is for emissions measurements only. It cannot be used for transmitting. The Active Monopole antenna is generally used in a shielded room or in a screen room, with the equipment under test (EUT) placed on a metal ground plane. The 41 inch rod and the ground plane behave electrically as though a mirror image of the rod were located below the ground, and the ground removed. Since the stainless steel plate does not have enough surface area to mirror the entire 41 inch rod, it is bonded to the surrounding ground plane during use. The AM-741 is battery powered to prevent measurement errors that maybe caused by external power cables. The ANSI equivalent capacitance substitution (ECSM) method is the recommended method for calibrating AM-741 monopole antenna. The individual calibration data will be included with each antenna.

Testing Large Radar Sensors with CATR Technology
CATR Radar Test System UTP 5069
Modern driver assistance systems must recognize increasingly complex traffic scenarios and convert them into appropriate vehicle reactions with the help of artificial intelligence (AI) and specific algorithms. Imaging radar sensors with a higher spatial resolution, so-called imaging radar sensors, are therefore required. These can better distinguish larger from smaller objects and, due to the larger antenna apertures, also require larger dimensions of the test environment or larger far-field distances. Testing these sensors in the direct far field ( UTP 5065 ) would therefore require very large absorber chambers up to ten meters in size and more.Our efficient test system UTP 5069 offers exactly the right solution:By using CATR technology (Compact Antenna Test Range), 4D, imaging and other radar sensors with large far-field distances are calibrated with high precision in a small footprint. With the extremely low-reflection NOFFZ absorber chamber, the system is very well suited not only for validation, but also for EOL tests.

MMW Field Sensors
ITS-9050
The Innovative Technical Systems ITS-9050 Detector is a sensitive, harmonic mixing detector designed to measure millimeter-wave free-space radiation. It is ideal for measuring radiation patterns of antennas inboth the near and far-field. The ITS-9050 employs a free-running dielectric resonator oscillator (DRO) and an integrated harmonic mixer with a waveguide RF input that either connects directly to a circuit under test or to an antenna for radiation detection. The resulting IF is amplified and detected by an IF log-detector that drives a front panel LCD voltmeter to provide an indication of signal strength. A DC output voltage from the log detector is available on a BNC connector to drive external data acquisition instrumentation. Also, a sample of the IF output is provided for measurement on a spectrum analyzer.
