Neutronics Manufacturing Co.
Introduction: Measuring the line loop contact resistance by bridges is not the ideal method as the test current is only a few milli amperes. Thus the value is not the true value of the contact resistance. Model HL- 100 is a direct reading tester, and uses a test current of 100A DC, resulting in true v alue and accur ate measurements. Model HL- 100 adopts digital circuit technique and is used for measuring contact resistance of switch control equipments at test current of 100A DC. The measurements are accurate as the test is highly stable.HL- 100 is a new, fully automatic micro controlled tester that measures contact resistance at 100A DC with built in printer. The advantages of HL-100

TYPE HFX-1 -
National RF, Inc
The Type HFX-1 Modulation Monitor is an ancillary piece of equipment, which is used with narrow bandwidth, or older oscilloscopes to allow viewing of RF signals and particularly modulated signals as high as 55MHz. The equipment contains an RF signal source and a broadband mixing circuit which converts the high frequency signal to an intermediate frequency within the oscilloscope’s range. The frequency control dial is simply adjusted until the RF signal is viewed on the scope. BNC connectors are mounted on the rear panel to allow interconnect to the scope and RF probe. This product was previously called "oscilloscope frequency extender" and may be used to view other high frequency signals on older or narrow band scopes.

Type NDB-2 and NDB-3 -
National RF, Inc
National RF’s Type NDB-2 and NDB-3 RF Milliwatt Meters are affordable pieces of test equipment for both the RF laboratory and the home experimenter. Both provide a digital reading of RF power in dB reference 1 milliwatt of power into a 50 ohm load (i.e. 0 dBm). The circuitry consists of a low noise logarithmic amplifier that drives a digital A/D converting meter circuit. The lowest power levels that can be read are about –73 dBm (approximately 40 microvolts or .00000003 milliwatts). The maximum power input should not exceed 10 milliwatts (+10 dBm or .010 watts) when inputed without attenuation. An internal attenuator is provided and described in the next section.

Testing House, Inc.
Design For Test (DFT) is a technique used to implement certain testability features into a product. Testing House can provide an analysis of the CAD data for testability of your circuit board. Access to a board can be very difficult as boards get smaller and designs get more densely populated. We can work with your design engineer to improve testability and maintain an effective in-circuit test. When access to the board is limited and boundary scan devices are present, we can provide the customer a list of key nodes that will require access in order to provide a very effective test. Our analysis will provide a list of all the accessible test points and an explanation for any nodes declared inaccessible.

ITS-9050 -
Innovative Technical Systems
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.

ERAVANT
Dielectric resonator oscillators (DRO) are free running oscillators that utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals with excellent frequency stability. In addition, these oscillators are equipped with an internal voltage regulator that further improves the frequency stability by isolating the external bias pushing and modulation. In general, these oscillators are fixed. However, a small mechanical or electrical tuning range can be achieved by use of a self-locking screw or an integrated Varactor diode. The standard offering covers the frequency range of 2 to 40 GHz. While standard models are equipped with female SMA and K connectors at the RF port, other RF interface options are also available.

SCR ELEKTRONIKS
SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.
