The RIK0039A consists of a single 40V Buffer board. It is used in the fixture when voltages other than what can be provided by a tester resource are required. It is configured to be used either with an active or passive carrier.
The 40V buffer board consists of 2 independent voltage multipliers. Each voltage multiplier will multiply an input voltage by 4X, up to 40V out. The multipliers can be disabled (set to approximately 0V) through the /E line, or disconnected through the /EO line. In addition, voltage and current monitors are provided.

|Voltage output 2. When /E and /EO are enabled, then O2 (Vout) = IN2 (Vin) X 4 Unloaded|
|Voltage output 1. When /E and /EO are enabled, then O1 (Vout) = IN1 (Vin) X 4 Unloaded|
|Disconnects the outputs (O1 and O2) when high, connects the outputs when low. Use Cbits for passive carrier drive. Use module strobe lines DS1-4 for active carriers**.|
|When low, enables the voltage multipliers, when high, sets the voltage multipliers to approx. 0V. Use module strobe lines DS1-4 for active carriers**.|
|Voltage input 2.|
|Voltage input 1.|
|Monitor I2. Voltage output is approx. 1V/ma*.|
|Monitor V2. Monitor voltage is approx. 0.28 x O2*.|
|Monitor I1. Voltage output is approx. 1V/ma*.|
|Monitor V1. Monitor voltage is approx. 0.28 x O1*.|
* Monitor outputs are not calibrated.
** SX1xxx enables power where X = number of module slot, x = don't care
SX0xxx disables power where X = number of module slot, x = don't care
SXx1xx enables outputs where X = number of module slot, x = don't care
SXx0xx disables outputs where X = number of module slot, x = don't care
Warning! Do note use Cbits to enable and disable voltages when using this module on a Smart Carrier.
