HIGH FREQUENCY DC BIAS
6565 SERIES
The 6565 HF DC Bias Unit is intended to be used with a Wayne Kerr 6500 analyzer, either the 6500B Precision Impedance Analyzer or the 6500P HF LCR Meter. Its function is to provide a source of DC bias current through the Device Under Test (DUT) while the analyzer is making AC measurements. Each 6565 unit can provide up to 10 A of DC current, and up to six 6565 units can be connected in parallel to supply a maximum 60 A. A digital ammeter on the front panel allows the user to see the dc bias current value and an indicator LED shows when the bias current is enabled.

2-18GHz Instantaneous Frequency Measurement Unit
DR058-F2
Teledyne Defence & Space’s Instantaneous Frequency Measurement (IFM) module, also known as a Digital Frequency Discriminator (DFD), offers high speed frequency measurement across the full operating bandwidth.The IFM measures the frequency of RF signal present at its input and presents a result at its output as digital data. The RF input signal is conditioned by an RF amplifier that provides sufficient drive for the frequency resolving circuits. The raw video from the resolvers is digitised and processed into the required output format. There is additional timing and control circuitry which initiates the measurement process and provides handshake data to the host system processor.

SparkFun Coulomb Counter Breakout
LTC4150
Odometers are extremely useful for cars, they tell you how far you have gone, wouldn't it be nice if you were able to have a device that does the same for electrical current? The LTC4150 SparkFun Coulomb Counter Breakout is here to be your odometer for current. If you are wondering: a coulomb is defined as, to put it simply, one amp for one second. This breakout is capable of constantly monitoring the current your sensor is using, is able to add it up, and will give you a pulse each time a given amount of amp-hours have been used. When used effectively and if you start with a full battery, you’ll always know exactly how much of it is left!

High Frequency 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.

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.
