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 VCC (via P15 and

P16) and +VS (via P1). See SA310 datasheet for acceptable voltage levels. The +VS 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: VCC, then +VS

Power OFF: +VS, then VCC

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.
