Equipment Requirements
3-2
3.1
Equipment Requirements
The following test equipment is required to use the EVM kit.
Power supply, 60 VDC at 6 amp minimum
Oscilloscope, 4 channel preferred (3 voltage probes and 1 current probe)
Digital voltmeter (DVM)
The availability of additional DVMs simplifies EVM use.
3.2
Verifying the EVM Operation
The following procedure steps may be used to verify functional operation of
the EVM after receipt.
3.2.1
Equipment Setup
1)
Do not connect the power supply to the EVM boards (HPA016 and
HPA018).
2)
If installed, remove the EVM main board (HPA016) from the P1B
connector of the EVM backplane board (HPA018).
3)
On the EVM main board (HPA016), set switch S1 to MANU.
4)
On the EVM backplane board (HPA018), set switch SW1 to OFF.
5)
Turn on the power supply. Set the output voltage of the supply to 48
±
0.2
VDC. On the supply, verify the output current limit control is set to allow
sourcing of at least 6 A.
6)
Turn off the power supply. Connect the power supply to the EVM back-
plane board (HPA018) as shown in Figure 31.
