UPS (Uninterruptible Power Supply)
-
The UPS (Uninterruptable Power Supply) by Allied Edison is a light weight (7.2 lbs), portable, non-variable source that converts a 12 Vdc Lithium Ion battery to output 110 vac sine wave at 60 hertz. It also has four 12Vdc output jacks, and 4 USB ports to power electronic equipment such as computers or used to supply cell phone chargers, etc. It has a strong built in flashlight. The UPS plugs into a standard 120 Vac, 60 hertz receptacle for charging and indicates percent battery capacity remaining on a digital meter located on the front panel. The UPS can also be charged by a solar cell, sold separately or can be plugged into a vehicles cigarette lighter receptacle for use in remote areas. The UPS is an excellent compliment to the VS-3 power supply where a technician needs a variable AC/DC source and cannot run a power cord due to the remoteness of the work area.

Proximity
-
Proximity detection sensors measure reflected infrared (IR) energy to detect the presence of an object or person. The devices include an integrated LED driver and, in some devices, an integrated LED. The proximity detection devices provide four programmable LED drive currents and IR pulse repetitions. The proximity detection circuitry compensates for ambient light, allowing it to operate in environments ranging from bright sunlight to dark rooms. The wide dynamic range allows operation in short-distance detection applications behind dark glass, such as mobile phones. Proximity detection sensors can be used to replace a mechanical switch or to sense human gestures.

RSE Wireless EMC Spurious Emission
TS8996
Test System
The R&S®TS8996 RSE test system is designed for EMI and radiated spurious emission testing on wireless devices in semi-anechoic or fully anechoic chambers. The modular design makes it easy to extend the system to include new communications technologies. Typical devices under test include mobile phones or radio sets along with radiated measurements of other short-range devices. Standards require a wide range of test setups and a wide and high frequency range (up to 40 GHz). ESW or FSW frequency ranges are extended up to 325 GHz with option B21 using receive units TC-RSE for 5G FR2. Dedicated RSE test routines are also covered for this frequency range.

Omnidirectional Antennas
-
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.[1][2] When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. Note that this is different from an isotropic antenna, which radiates equal power in all directions, having a spherical radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.

Chip Scale TVS Arrays
-
ProTek's patented* Flip Chip TVS Arrays are designed for small circuit board applications with limited size and space availability. To reduce installation costs, the Flip Chip can be mounted directly onto the printed circuit board; similar to chip resistors and capacitors. These devices are ideal for use in portable electronics such as Cellular Phones, Cellular Phone Accessories, Personal Digital Assistants (PDAs), Laptops and Pagers.
