The CWS 500 is a single unit designed for 150 Ohm system testing to EN61000-4-6 and includes a kit containing necessary leads and 6dB attenuator.
The CWS 500 unit essentially has a built in signal generator, a power amplifier, and a directional coupler with volt meter.
The unit has its own calibration and test routine run from the front panel.
You will require an additional ground plane (Item 817) along with either a BCI Probe (Item 258 & 251) or EM Clamp (Item 254) as shown in the pictures above.
NOTE: BCI Clamp Injection will require additional 50-150Ω adaptors (Item 256).
