MOS-01, -01A -
Compact Power Company
The MOS-01 manual oscillator module is used as a quality, general-purpose sinewave oscillator and digital readout monitoring system in the MAC-01, -02, or -03 AC Power Sources/Frequency Converters. The unit has guaranteed operating range of 20 HZ to 20 KHZ which is covered in three one-decade scales. The LCD digital metering system is switch-selectable to readout either frequency, voltage or current. A toggle switch selects the input for the attached AC Power Source/Frequency Converter to originate from the manual oscillator itself or from an external laboratory or programmable oscillator source. With oscillator mode switch in Internal position, the BNC connector delivers the signal to drive additional slave units or for oscilloscope sync or monitoring. BNC input/output is completely isolated with 1500 VAC breakdown and excellent common mode rejection. The oscillator modules must be factory installed and calibrated.

HFDF -
National RF, Inc
National RF's Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum. Due to the nature of a Faraday shielded loop, the antenna exhibits a sharp null through the diametric center of the loop. This null is used to determine the direction of incoming radio signals or to locate electrical noise being radiated from some source. The internal high gain amplifier is used to compensate for the inherent inefficiency of the actual loop at the operating frequency. Overall, the system dynamic response is about +6 dB as compared to the dynamic response of a dipole. To aid in the direction finding process on strong signals, an internal 30 DB attenuator is provided. As the loop antenna presents a bi-directional response, tri-angulation may be required to eliminate the ambiguous signal direction. The line of site of the incoming signal is determined by listening for a signal null on the receiver or by watching the receiver’s S-meter.

YD-Series -
Chongqing Gold Mechanical & Electrical Equipment Co.,Ltd
YD series HIPOT tester is applied to test the insulation ability of electric power equipments and insulation materials at power frequency high voltage. The insulation test result of the tester is go or not go. Also the YD series HIPOT tester is a universal power source in HV test. The maximum output voltage and capacity could be customized according the requirements of custom.The tester is consists of single HV transformer and main control box. There are two kinds of HV transformer according to the insulation materials of the HV transformer.They are dry HV transformer and oil HV transformer. For the dry HV transformer the insulation material is epoxy resin.For oil HV transformer the insulation material is insulation oil. The dry HV transformer has a smaller size and less weight than oil HV transformer. But the maximum output voltage is less than 100kv for dry HV transformer. The functions of the main control box are voltage output regulation, protection in emergency and voltage/current value indication

Signals & Systems India Private Limited
GPS Master Clock System – MCS-GPSMC-1010 is a 3U Card rack type, 19” Rack-mountable Redundant GPS Time Server which synchronizes and maintains the timing and frequency requirement of power and process industry equipment using a signal obtained from any one of the sources like GPS or GLONASS or Time protocols such as NTP and IRIG. It distributing the same time signal through several types of interfaces. It provides redundancy for Power and GPS receiver to increase reliability and offers protection against time synchronization failure. The system is field-upgradeable and an extremely flexible system, designed to handle time synchronization requirements today and in the future. It provides nanosecond accuracy when external time references are not available. It has a storage facility to store the system log file. It delivers NTP, SNTP, IRIG-B, PFC-Pulse, DCF77, BCD parallel data, Ethernet Fiber Optic & RS485/RS232 outputs. System enables configuration and monitoring through Web-based application. It supports a wide range of power supply either 90V-260V AC/DC or 18-36VDC or 36V-72VDC. Power supply model can be mixed and matched as required by the user, depending upon power supply options available at the installation site.

AG-51 -
Potomac Instruments, Inc.
The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements.
