Silicon pad sensors are proposed as active material in highly granularsampling calorimeters of future collider experiments such as the Compact LinearCollider (CLIC) or the International Linear Collider (ILC). The electromagneticsection of these designs often include O(1000 m$^2$) of silicon pad sensors.For the luminosity measurement, a dedicated forward calorimeter called LumiCalis foreseen. More recently, the CMS experiment has decided to adopt the sameconcept in its endcap calorimeter upgrade for the HL-LHC. The sensors aretypically produced from 6- or 8-inch wafers and consist of a few hundredsmaller cells, each with an area of O(0.1 to 1 $\text{cm}^2$). For theprototyping phase of these projects, several design choices have to beevaluated while for mass production, thousands of sensors have to be tested forquality control. For the electrical characterisation of these sensors, it isimportant to bias them under realistic conditions. To fulfil theserequirements, ARRAY, a compact, modular and cost efficient system for largearea silicon pad sensor characterisation has been developed and successfullycommissioned. It consists of two plugin printed circuit boards: an activeswitching matrix with 512 input channels that holds all controls and a passiveprobe card that connects to the sensor. The latter can then be adapted to anysensor geometry. All design files are open source. The system has been used tomeasure currents ranging from 500 pA to 5 $\mu$A and capacitances between 5 pFand 100 pF. A precision of better than 0.2 pF on capacitance measurements inthat range can be achieved. Examples of calibration and measurement results forleakage current and capacitance are presented.
