9 LED RF Output
When the RF output is active this LED on the front panel is illuminated to indicate that a test signal is
applied to the test object.
10 RF-Output
At this output the RF power is available. The 6dB-attenuator is connected via coaxial cable. For conducting
tests together with CDN’s, EM clamps or current injection clamps, the generator must always be loaded
with a 6dB-attenuator as per IEC 61000-4-6 (see chapter Test Setup).
11 Current Probe Input
For tests with a coupling clamp where the EUT current has to be monitored, the current probe can be
connected to this input.
ATTENTION: Do not connect the RF output directly to this input otherwise the
CWS500 might damage.
