o +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 RMS,and the following user selectable filters: Highpass:50HZ,300HZ,and 3KHZ Bandpass:None,1KHZ,10KHZ,19KHZ,38KHZ,and Distortion The CBITS/MBITS board Card solt five contains the CBITS/MBITS board,which provides 32 control lines to the performance board,and 16 readback bits(MBITS) form the performance board. The large timer board The large timer board is located in card slot six,and is used to measure the elapsed time between two events,or to count the number of events which occurred during a known time interval. The handler control board The handler control board provides the interface between the DTS and the device handler or receives a start test signal from the handler when a decice is sitting in the handler`s contacts and is ready for testing has been pleted,the handler control board provides a bin result and the end of test signal to the handler. Audio source board Card slot eight contains the audio source board,which is a programmable waveform generator capable of producing arbitrary wav。
