Equipment required
(Item 5) High current hook up wire
(bold line connections)
(Item 12) Oscilloscope
(Item 10) Load Resistor (Item 13) Oscilloscope 1X probe
For each channel sequentially.
1. Plug the DUT into your local line power from the mains.
2. Plug the test oscilloscope into the same mains outlet as the DUT.
NOTE. Some AC Power Sources create large amounts of high frequency noise on
the power line that the instrument may not fully reject. Noise directly on the mains
is typically better controlled.
Use the same mains outlet for both the DUT and test oscilloscope to avoid ground
loops which may cause noise.
3. Power on the DUT and test oscilloscope.
NOTE. Ensure the warm-up criteria has be en met as described in the Performance
Verifi
cation Conditions.
4. Set up the equipment a s shown. (See Figure 7.)
Use the appropriate load resistor depending on the channel being tested. (See
Table 24 on page 22.)
