The ASBus is intended to connect modules of the same type i e of the same model number although some exceptions to this rule might be possible If modules with the same model number but different memory length options are connected only the shortest memory length can be used The ASBus connector is located on the front panel of each module Bridges are used to connect adjacent modules for synchronization which is then activated through software by defining a master module and the trigger source Up to 7 modules may be synchronized with the ASBus More detailed information and the commands required to set up the ASBus clock and trigger distribution are included in the Programmer s Guide and Reference manual User Manual Family of 12 bit Digitizers Page 41 of 65 acqiris 3 8 Special Front Panel Inputs and Controls Connector Function MMCxX CLK IN External Reference or External Clock MMCX I O A User configurable see below MMCX TR OUT Signal occurs after an accepted TRIGGER MMCX I O B User configurable see below The I O A and I O B signals are 3 3 V compatible CMOS This means that on input low is lt 0 7 V and high must be in the range 1 7 V 5 0 V An unconnected signal will be high This definition ensures TTL compatibility On output the low level will be in the range 0 V 0 7 V and the high level in the range 1 7 V 3 3 V for HiZ The high level output will typically give 0 8 V into 50 Q The I O A or B

The External Clock function is available in AcqirisLive only when using the control panel in Transient Recorder mode The input frequency should be keyed into the clock frequency selector outlined in red on the control panel in order for the proper timebase to be displayed on the waveform display window The time window displayed can be manipulated by allocating more or less memory to the acquisition The External 10 MHz Reference in AcgirisLive is designed to work either in Oscilloscope mode or in Transient Recorder mode The timebase and sample rate for waveform capture is fully selectable when using the external reference just as it is when using the digitizer s own internal reference clock 4 8 Additional Waveform Information The Options menu also includes possibilities to obtain additional information about the waveform In both cases described below the display will be updated after each acquisition The Show Segment Timestamps option shows a display like the one below eee ains It gives you the information needed to better understand the trigger Average Sev times of the individual segments of an acquisition By definition the first trigger of an acquisition occurs at t 0 0 There are two columns for each digitizer For the n th row the first column contains the difference ta ty and the second column contains ta The top line contains the average value of the t in the left column and the standard deviation of the
