TEST ASSEMBLY
EQUIPMENT NEEDED
1. Power Supplies
2. Digital Controller or 6+ Channel Pattern Generator
3. Oscilloscope
4. Proper Heatsinking System
TEST SETUP
Make sure all supplies are turned off before connection. Connect the power supplies V
CC
(via P15 and
P16) and +V
S
(via P1). See SA310 datasheet for acceptable voltage levels. The +V
S
LED will be visibly bright for
voltages 30V and above. For lower voltages, consider using a smaller-value resistor for R8.
When sequencing power supplies, use the following order:
Power ON: V
CC
, then +V
S
Power OFF: +V
S
, then V
CC
It is recommended to first test the device with no load attached. Ensure the output waveform follows the
expected results before connecting a load. Consider power dissipation in the amplifier, sense resistors, and
the load.
The BNC connectors P3, P4, and P5 are designed for coaxial measurement of the output; these are not
meant to carry significant current. ONLY USE P1 FOR HIGH-CURRENT CONNECTIONS. To use P3-P5, for volt
-
ages within the oscilloscope's input rating, BNC cables may be used to connect directly to the oscilloscope.
For higher voltages, use a high-voltage oscilloscope probe with a probe-tip-to-BNC adapter. Alternatively, use
high-voltage BNC attenuators in series with the BNC cable.
