The Probix adapter HX0093 is a specific accessory for the SCOPIX oscilloscopes of the OX 9000 and OX 7000 series. It serves as a connection adapter for measurement devices with Ø 4 mm plugs, particularly for voltage measurements. The adapter features an integrated low-pass filter of 3rd order with a cutoff frequency of 300 Hz, which can filter out the fundamental frequency of 50 Hz or 60 Hz. This is particularly useful for analyzing PWM-controlled electric drives, where the fundamental wave is often superimposed and precise representation of the modulation structure is required.

Applications

The adapter is designed for professional applications in electrical engineering and power electronics. It is used to remove high-frequency interference or unwanted fundamental wave components from measurement signals, thereby improving signal quality. The application is particularly relevant for diagnosing and developing drive systems operated via PWM control.

Functions and Equipment in Detail

The adapter enables direct connection of accessories with Ø 4 mm plugs to the oscilloscope via the Probix connector. The integrated filter function with a bandwidth of 300 Hz ensures that only frequencies below this limit are passed. The attenuation is 1000:1, meaning a high signal reduction for frequencies above the cutoff frequency. The safety class 600 V CAT III ensures safe use in industrial environments with high voltages.

Technology Explained Simply

A low-pass filter of 3rd order reduces the amplitude of frequencies above the cutoff frequency in a steep slope. The attenuation of 1000:1 means that signals above 300 Hz are reduced by a factor of 1000. This is crucial for filtering the fundamental frequency (50 Hz or 60 Hz) during PWM measurements without affecting the low-frequency modulation components. Power supply and calibration are provided directly by the oscilloscope, enabling quick and error-free commissioning.

Compatibility and Accessories

The adapter is exclusively compatible with SCOPIX oscilloscopes of the OX 9000 and OX 7000 series. It is part of the PROBIX accessory system, which enables automatic detection and configuration of connected devices. The oscilloscope identifies the adapter upon connection and automatically adjusts to its properties.

Installation and Mounting

Installation is performed by directly inserting the adapter into the Probix connector of the oscilloscope. Connection to measurement probes or other devices with Ø 4 mm plugs is made via the integrated socket. Automatic detection ensures no manual settings are required. Power supply and calibration are handled by the oscilloscope, ensuring simple and safe operation.

Advantages in Operation

Using the adapter reduces complexity when measuring PWM signals, as the fundamental frequency is automatically filtered out. The high safety class 600 V CAT III allows use in industrial applications. Direct power supply and calibration via the oscilloscope reduce error susceptibility and speed up the measurement process. Automatic detection and configuration enable quick commissioning without manual adjustments.

Scope of Delivery

The adapter is delivered with documentation. The documentation includes technical information and operating instructions for safe and correct use of the adapter.
