| Antennas |  |
Tekbox Measurement antennas are used for standard compliant radiated emission measurements in the far-field. The antenna portfolio includes CISPR bands B, C, D, and E. Every Tekbox antenna is characterised by an antenna factor. The electrical field strength in dBµV/m is obtained by adding the antenna factor in [dB/m] to the measured antenna output voltage in [dBµV]. All Tekbox antennas have a 1/4 inch thread for tripod mounting. The TBMA1 and TBMA4 antennas are bundled with a tripod TBTP2. The TBMA1, TBMA3 and TBMA5 antennas are packaged in a carrying case. | £93.45 View Lowest Price Product Aaronia OmniLOG 90200 Broadband Omni-Directional Antenna 700MHz to 2.5GHz |

<div class="SC_product_table2"> <div class="page_table"> Tekbox Wideband RF power amplifiers and RF signal generators are critical components in both radiated and conducted immunity tests. The combined cost of the requisite immunity test equipment is prohibitively expensive for pre-compliance applications. Tekbox created a low-cost solution comprised of modulated RF power amplifiers driven by spectrum analyser tracking generators. Tekbox amplifiers include built-in modulators that produce the typical modulation forms defined by the applicable standards, as tracking generators provide a CW output signal: 1 kHz, 80% AM, 1 kHz, 50% duty cycle PM, 217 Hz, 12.5% duty cycle PM. The Tekbox EMCview software controls the frequency and output power of the tracking generator during testing. Depending on model, our amplifiers currently cover the frequency range from 100 kHz to 1.5 GHz and the available output power covers the range from 150 mW to 25 W. The modulated amplifiers are suitable for pre-compliance radiated immunity testing in TEM cells and pre-compliance conducted immunity testing with CDNs or bulk current injection probes. <h3>MODULATED

| TEM Cells |  |
Radiated emission tests are typically carried out in anechoic chambers, using antennas to pick up the radiated signals. Due to bandwidth limitations, several antennas are required to cover the complete frequency range. Furthermore, it requires much space and the cost of the equipment for a standard conformant setup is immense. An engineer of a small or medium size enterprise usually has to rely on his experience and on best practice methods in order to design an EMC compliant product. Nevertheless, it is estimated that > 50% of products fail testing first time around. Anytime an engineer sends a new product for compliance testing, it is a shot in the dark. Failing is very expensive. Not only that re-testing costs are high, but also the project schedule and market introduction gets delayed. What is needed is an affordable laboratory set up to measure radiated emissions in the own lab, prior to compliance testing. A TEM cell is the right piece of equipment for desktop testing of radiated emissions. Tekbox developed open TEM cells to cover the complete frequency range up to 2GHz and with usability even at frequencies beyond. Combined with a spectrum analyser, products can be tested before and after EMC related design modifications. A set up with a TEM cell will not deliver exactly the same quantitative results as a measurement in a certified test house, however it will give an excellent indication on whether the design suffers from excessive radiated noise or not. The engineer will clearly see, whether his changes improved or deteriorated the EMC performance or whether it remained unchanged. Using TEM cells eliminates the guesswork. A TEM cell is a stripline device for radiated emissions and immunity testing of electronic devices. It is not a replacement, but due to its size and cost it is a convenient alternative to measurements in an anechoic chamber. A TEM cell consists of a septum, the conductive strip in the centre section and walls which are connected to ground. The geometry is designed to present a 50Ω stripline. The device under test (DUT) is placed in between the bottom wall and the septum. The TBTC1/2/3 are so called “open TEM cells”, which got no side walls for convenient placement of the DUT. It may pick up RF background noise, which however can be taken into account by doing a measurement of the cell output signal before powering on the DUT. Tekbox open TEM cells got a better frequency response compared to standard TEM cells of similar size. TEM cells suffer from higher order wave modes which limit the usable bandwidth. A unique design feature of the Tekbox TEM cells implements resistance perpendicular to the desired propagation direction of the wave. Consequently higher order wave modes and resonances are suppressed. All TEM cells are supplied together with a 50Ω/25W RF termination, a DC block to protect the spectrum analyser or RF receiver input and a N-Male to N-Male coaxial cable. | £421.32 View Lowest Price Product TEKBOX TBTC0 Open TEM Cell |
