【正文】 digital backplane for controlling each digital backplane is connected to the puter via the IBUS cabling. The power V/I source is a special instrument that ,when installed in the system ,is mounted inside the back door as opposed to being in the card rack. The measurement board Card slot one contains the measurement measurement board is a differential DC voltmeter with a maximum input voltage of +65V to measurement board has three measurement ranges,65V,20V,and 2V. The cross point matrix board Card slot two holds the cross point matrix cross matrix board consists of three sections:a timer interval generator,a sixteen input measurement matrix,The time interval generator is used to time and control program waits in the DTS measurement matrix is input matrix for the measurement provides sixteen that can be used to connect the measurement board to different measurement points on the load board. The voltage source/nanoammeters(vs/na) board Provides eight individually programmable voltage sources capable of forcing voltages from 65V DC to +65V DC at currents up to sources one through four also have built in current measurement VS/NA board is located in card slot three of the instrument card rack.。 The VS/NA board has two voltage forcing DS and 10V has two current measurentment ranges,a 20uA range ang a 2uA range. The audio voltmeter(AVM) board Card solt four holds the audio voltmeter board,which provides the capability of measuring AC signals in the audio frequency AVM board provides DC suppression and filtering of the input signal,and has an input frequence range of 50HZ and AVM has six voltmeter ranges:16,4,and
