5. Current Sense Resistor

Figure 6. Current Sense Resistor Location

Each device site has a 1.0

 resistor in series with the VDD supply of that device. Both sides of that resistor are

connected to a set of test points. This test point pair can be used to measure the voltage across that supply

resistor, which indicates the supply current consumed by the respective device.

6. Outputs

Figure 7. SMA Outputs

Each device site output is connected to a SMA connector through a series resistor. J1 is the SMA connector output

of the on-board Si504, with J2 through J4 corresponding to evaluation sites U2 through U4.
