Disciplined Frequency Standards
2960AR and 2965AR
-
The 2960AR has a rubidium timebase and provides two 10MHz and one 5MHz sine wave outputs. The 2965AR has a rubidium timebase and provides one 10MHz, one 5MHz and one signal generator output. The signal generator output uses Direct Digital Synthesizer (DDS) technology and is programmable from 100Hz to 50MHz via an RS232 serial interface. Both models can be disciplined by a 1pps input signal and provide a 1pps output. The 1pps input is typically provided by the GPS Frequency output from a device like a smart GPS receiver or antenna. The Novatech GPS1 Smart Antenna is available as an accessory to provide a complete turnkey solution.

Audio Frequency Generator
TM530
-
TM530 Audio Frequency Generator is provided with Pinpoint Fault Locator for pinpointing the low resistance fault and detecting cable route. When detecting, TM530 will inject a signal current of 1kHz audio frequency into the cable, and accordingly a magnetic wave of the corresponding frequency will be generated on the cable. Pinpoint Fault Locator will collect this magnetic signal, thus obtains the information of the cable fault and the route.

High Frequency Current Transformers
-
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.
