EVM Setup

The following instructions are for setting up the EVM:

  1. The control inputs and signal lines may be loaded by soldering components to signal path pads as needed. describes which load pads correspond to what pin on the DUT. SMA connectors can be soldered to corresponding pads accordingly.

  2. The board is powered by attaching ±5 V to ±22 V dual power supply or 5 V to 44 V single power supply to the screw terminal J2, with VDD, VSS, and GND oriented as specified in Table 6-1.
  3. Jumpers should be placed according to desired functionality. Figure 5-1 displays a generic four-pin jumper, with the indicating white corner to designate position 1.
