Remote Probes – the next evolution in power analysis technology

Remote probes function as decentralised analyzer cards, transmitting digital data through fibre optic cables to the mainframe. This allows remote probes to be positioned close to the measurement object, with short, high-voltage cables from the device under test to the remote probe. This configuration minimises EMC influences caused by long cables and enhances safety due to the use of fibre optic connections between the remote probe and mainframe.

In contrast, power analyzer cards are centrally located in the mainframe, necessitating longer high-voltage cables from the device under test to the analyzer card/mainframe, leading to potential EMC disturbances and requiring additional safety precautions.

Calibrating remote probes is straightforward because they are not located in the mainframe. Simply disconnect the signal connections and power receiver card to send them to HBK for calibration.

Remote probes transmit digital information through fibre optic cables to the input card in the mainframe. To support two remote probes, a GN800B power receiver card is required in the mainframe, along with one fibre optic cable per remote probe. These components can be conveniently ordered through HBK.

The maximum length for fibre optic cables between a remote probe and the GN800B power receiver card in the mainframe is 100 m. Remote probes are equipped with a length compensation mechanism, ensuring real-time data accuracy regardless of the fibre optic cable length. The lengths of two remote probes connected to the same GN800B power receiver card can vary. Each remote probe has four channels and requires one fibre optic cable per probe.

HBK provides two types of remote probes designed for measuring either voltage or current. Each type can be used independently or together on the same GN800B receiver card to measure, for example, electric motor power.

Remote probes are designed to function within a temperature range of 0°C to 40°C and can operate under a relative humidity of up to 80%. They have an IP20 protection rating, and are certified for vibration and shock resistance, ensuring safe and accurate handling even in demanding measurement environments.

Yes, the remote probes are designed to perform the same real-time calculations as other Genesis HighSpeed products. These high-speed, high-accuracy devices greatly enhance any high-speed measurement system.

Unfortunately, the artificial star adapter^TM cannot currently be used with the remote probes.

The remote probes require an external power supply of 115/230 V.

When using zero-flux current transducers such as the HBK CTS-series, you have the option to order a remote probe with an integrated power supply for the current transducers. In this case, there is no need for an external power supply for the current transducers.
