HFI 02

RF measurements on signal lines with a throughput of up to 10 Mbit can be carried out with the HFI 02. Controlling a graphic display is a typical example. The corresponding filters can thus be optimized and screenings reduced.
The RF current transformer operates in the frequency range between 100 kHz and 3 GHz and enables RF current measurements in connection with a spectrum analyzer.
A small mounting bracket (accessory) is fixed on the GND of the unit under test, the RF current transformer plugged on and the current to be measured led through the transformer via a CuL wire to measure the current.
The transformer couples an induced voltage to the 50 O SMB output. Common-mode and sheath currents are damped in the transformer shaft. The measured values are transferred to a spectrum analyser or oszillograph via a shielded cable.

HFU 02

RF voltage measurement can be carried out with the HFU 02 on critical signal pins, microcontroller pins, quartz terminals and metallic structural parts with no interfrerence. Due to its high sensitivity the HFU 02 is particularly suitable for modules with a low RF voltage such as modules typical for the automotive industry.
The very high resolution and low interference with the unit under test enable the evaluation of data lines operating at 100 MHz, for example.
The HFU 02 typa A (coupling capacity near 20 pF) is used for measurements on quartz pins or other high impedance pins in the frequency range between 10 MHz and 3 GHz. The HFU 02 type B (coupling capacity near 3 nF) is used for measurements especially in lower frequency range. The HFU 02 is connected to GND of the module and the relevant line is contacted via a tip (included in the scope of delivery).
