WGxx Arbitrary Waveform Generator First Steps
• In case of replacement of fuses it has to be guaranteed that the replacement
components show the specified current/voltage rates and the
specified interruption characteristic (standard/fast/slow).
Any bypassing of fuses (shortage) is strictly not allowed!
• To avoid the risk of injury by electric current it has to be guaranteed that
any opening of the instrument in case of repair has to be performed with
disconnected power cord exclusively by qualified service personnel.
• In case of the possibility of a broken protective earth ground connection
the instrument immediately has to be taken out of operation; furthermore,
it has to be guaranteed that a inadvertent re-operation is avoided. This
also is true for the case that the instrument shows mechanical damages
or in case that the display remains inactive if the instrument is turned on.
• Capacitors inside the instrument can show dangerous voltages even if
the instrument is disconnected from the facility power outlet!
• The instruments WG810 and WG820 are operated with a wall-outlet
power supply unit. The arbitrary waveform generator shows a nominal
input voltage of 12V AC (safety class II). The instrument has to be
operated exclusively by application of the included power supply device.
The cabinet of WG810 and WG820 (which are supplied by a wall-outlet
power supply) is not connected to the protective earth ground.
Isolated Signal Output
The instruments feature isolated signal output which is of advantage for many
applications which require testing signals not referenced to protective earth in
order to avoid ground loops or to minimize common mode noise.
The BNC-output terminals of the WGxxx instrument family are not connected
to the protective earth ground (case). However, the voltage between signal
ground (BNC terminals) and protective earth ground must not exceed 42V:
max. voltage between BNC terminals and protective earth ground: 42V
