Quick Setup Guide
!Warning: The generator can produce lethal voltages, please note the
following before powering it on:
• The device must be properly grounded before the mains voltage is
applied. The device is intended to be mounted on a flange of a vac-
uum apparatus and grounded to it. Check the ground resistance in
case of any doubts.
• The output circuit must be connected by short wires with sufficiently
low impedance, please do not neglect skin effect. The generator
produces high-amplitude, high-frequency voltages. If not properly
connected and grounded, it may cause RF emissions with a high in-
tensity that may interfere with other devices. Thin output wires with a
high inductance will not provide a sufficient connection between the
output transformer and the load. This may lead to high-frequency
oscillations at the transformer output accompanied by high-
amplitude voltage peaks at the MOSFETs of the power stage. This
may limit the amplitude of the output voltage or even damage the
power stage.
• The device has been adjusted to the frequency and load specified
by the customer. For the exact test conditions, see the test protocol
provided with the device. When the device is put into operation,
compare the supply values with the test protocol and do not proceed
if there is a significant difference.
Connect the mains to the IEC inlet Line Input on the front panel (see
Fig. 1) via a standard line cord with the universal IEC mains lead. Turn
the device on via the switch integrated into the IEC inlet. The LED in-
dicator Driver Power should change color several times and, after the
startup sequence finishes, it should light up green — this indicates
that the device is enabled. Short the BNC socket Enable with a 50 Ω
terminator or apply a logical 0 to the input in another way. The LED
indicator should change to yellow, indicating that the generator is dis-
abled.
!Warning: If the LED indicator has any other color, see the section
"Technical Data" for an explanation of the indicated states and consult
the section "Troubleshooting". Do not proceed until the failure has
been resolved.
If the device works as expected, turn it off again and disconnect it
from the mains. Mount it to the flange and connect the electrodes to
