    Installing the board in the system Hardware Installation Installing a board with digital inputs/outputs The locks on the top and bottom side of both CompactPCI brackets need to be unlocked and opened before installing the board into a free slot of the system. Therefore you need to press the little buttons on the inside of the fasteners and move them outwards (see figure). Now slowly insert the card into the host system using the key ways until both locks snap in with a „click“.

  • Page 15: Installing Multiple Boards Synchronized By Starhub

    Spectrum ships the boards together with the needed amount of synchronization ca- bles. All of them are matched to the same length, to achieve a zero clock delay between the boards.

  • Page 16: Installing Multiple Synchronized Boards

    Hooking up the boards Before mounting several synchronized boards for a multi channel system into the chassis you have to hook up the boards with their syncronization cables first. Spectrum ships the boards together with the needed synchronization cable. All of the possible four boards must be wired with deliv- ered synchronization cable.

  • Page 17: Software Driver Installation

    Most available drivers and also the Spectrum driver for your board can manage interrupt sharing. But there are also some drivers on the market that can only use one interrupt exclusively. If this equipment shares an interrupt with the Spectrum board, the system will hang up if the second driver is loaded (the time is depending on the operating system).

  • Page 30 C/C++ Driver Interface Software Function SpcSetAdr This function is only available under Linux. It is intended to program one of the FIFO buffer addresses to the driver. Depending on the platform (32 bit or 64 bit) the address parameter has a matching pointer size of 32 bit or 64 bit. This function can be used with Linux 32 bit as well as Linux 64 bit installations.

  • Page 31: Delphi (Pascal) Programming Interface

    Type definition All Spectrum driver functions are using pre-defined variable types to cover different operating systems and to use the same driver interface for all programming languages. Under Delphi it is necessary to define these types once. This is also shown in the examples delivered on CD.

  • Page 32: Visual Basic Programming Interface

    Visual Basic Programming Interface The Spectrum boards can be used together with Microsoft Visual Basic as well as with Microsoft Visual Basic for Applications. This allows per example the direct access of the hardware from within Microsoft Excel. The interface between the programming language and the driver is the same for both.

    These registers are set by the driver after the PCI initialization. The information is found in the on-board EEPROM, and can easily be read out by your own application software. All of the following PCI registers are read only. You get access to all registers by using the Spectrum function SpcGetParam with one of the following registers.

  • Page 37: Hardware Version

    Hardware version Since all of the MI, MC and MX boards from Spectrum are modular boards, they consist of one base board and one or two (only PCI and CompactPCI) piggy-back modules. This register SPC_PCIVERSION gives information about the revision of either the base board and the mod- ules.

If on no synchronized board the starhub option is installed, the boards are synchronized with the cascading option.

  • Page 39: Example Program For The Board Initialization

    Powerdown and reset Every Spectrum board can be set to powerdown mode by software. In this mode the board is therefore consuming less power than in normal operation mode. The amount of saved power is board dependant. Please refer to the technical data section for details. The board can be set to normal mode again either by performing a reset as mentioned below or by starting the board as described in the according chapters later in this manual.

  • Page 40: Analog Inputs

    Channel Selection One key setting that influences all other possible settings is the channel enable register. An unique feature of the Spectrum boards is the possibility to program the number of channels you want to use. All on-board memory can then be used by these activated channels.

  • Page 42: Automatic On-Board Calibration Of The Offset And Gain Settings

    As all settings are temporarily stored in the driver, the automatic adjustment will only affect these values. After exiting your program, all cal- ibration information will be lost. To give you a possibility to save your own settings, most Spectrum card have at least one set of user settings that can be saved within the on-board EEPROM.

  • Page 43: Standard Acquisition Modes

    General Information The standard mode is the easiest and mostly used mode to acquire analog data with a Spectrum A/D board. In standard recording mode the board is working totally independant from the host system (in most cases a standard PC), after the board setup is done. The advantage of the Spectrum boards is that regardless to the system usage the board will sample with equidistant time intervals.

  • Page 48: Fifo Mode

    Overview FIFO Mode FIFO Mode Overview General Information The FIFO mode allows to record data continuously and trans- fer it online to the PC (acquisition boards) or allows to write data continuously from the PC to the board (generation boards). Therefore the on-board memory of the board is used as a continuous buffer.

  • Page 49: Programming

    Each FIFO buffer can be a maximum of half the memory. Be aware that the buffer length is given in overall bytes not in samples. Therefore the value has to be calculated depending on the activated channels and the resolution of the board: (c) Spectrum GmbH...

  • Page 50: Buffer Processing

    2 x [Samples in Buffer] We at Spectrum achieved best results when programming the buffer length to a number of samples that can hold approximately 100 ms of data. However if going to the limit of the PCI bus with the FIFO mode or when having buffer overruns it can be useful to have larger FIFO buffers to buffer more data in it.

  • Page 53: Clock Generation

    Overview The Spectrum boards offer a wide variety of different clock modes to match all the customers needs. All the clock modes are described in detail with programming examples below. This chapter simply gives you an overview which clock mode to select: Standard internal sample rate PLL with internal 40 MHz reference.

  • Page 54: Using Plain Quartz Without Pll

    Using plain quartz without PLL In some cases it is useful for the application not to have the on-board PLL activated. Although the PLL used on the Spectrum boards is a low- jitter version it still produces more clock jitter than a plain quartz oscillator. For these cases the Spectrum boards have the opportunity to switch off the PLL by software and use a simple clock divider.

  • Page 55: External Clocking

    Standard/FIFO How to read this table? No matter what sampling rate you activate, the external clock range always has to be set to EXRANGE_SINGLE. (c) Spectrum GmbH...

  • Page 57: Trigger Modes And Appendant Registers

    Trigger modes and appendant registers General Description The trigger modes of the Spectrum MI, MC and MX A/D boards are very complex and give you the possibility to detect nearly any trigger event, you can think of. You can choose between seven external TTL trigger modes and up to 18 internal trigger modes including software and channel trigger, de- pending on your type of board.

  • Page 58: Edge Triggers

    External TTL trigger Trigger modes and appendant registers If you choose an external trigger mode the SPC_TRIGGEROUT register will be overwritten and the trigger connector will be used as an input anyways. Register Value Direction Description SPC_TRIGGEROUT 40100 Defines the data direction of the external trigger connector. If external triggermodes are used, this register will have no effect.

  • Page 59: Pulsewidth Triggers

    Sets the pulsewidth in samples. Values from 2 to 255 are allowed. SPC_TRIGGERMODE 40000 Sets the triggermode for the board. TM_TTLHIGH_SP 20002 Sets the trigger mode for external TTL trigger to detect HIGH pulses that are shorter than a programmed pulsewidth. (c) Spectrum GmbH...

  • Page 60: Channel Trigger

    Channel Trigger Trigger modes and appendant registers TTL pulsewidth trigger for long LOW pulses This mode is for detecting LOW pulses of an external TTL signal that are longer than a programmed pulsewidth. If the pulse is shorter than the programmed pulsewidth, no trigger will be de- tected.

    Defines the upper level (triggerlevel) for channel 15 -8000 to +8000 SPC_LOWLEVEL0 42100 read/write Defines the lower level (triggerlevel) for channel 0 -8000 to +8000 SPC_LOWLEVEL1 42101 read/write Defines the lower level (triggerlevel) for channel 1 -8000 to +8000 (c) Spectrum GmbH...
  • Page 62 Reading out the number of possible trigger levels The Spectrum driver also contains a register, that holds the value of the maximum possible different trigger levels considering the above men- tioned exclusion of the most negative possible value. This is useful, as new drivers can also be used with older hardware versions, because you can check the trigger resolution during runtime.

  • Page 74: Analog Outputs

    Analog Outputs Option Extra I/O Analog Outputs In addition to the digital I/Os there are four analog outputs available. These outputs are directly programmed with the voltage values in mV. As the analog outputs are driven by a 12 bit DAC, the output voltage can be set in a stepsize of 5 mV. The table below shows the registers, you must write the desired levels too.

  • Page 75: Synchronization (Option)

    With the option starhub up to 16 Spectrum boards can be synchronized. All boards are connected with a seperate synchronization cable from their sync-connectors to the starhub module, which is a piggy-back module on one Spectrum board (for details please refer to the chapter about installing the hardware).

  • Page 76: The Setup Order For The Different Synchronization Options

    The setup order for the different synchronization options Synchronization (Option) When the boards are synchronized by the option starhub there will be no delay between the connected boards. This is achieved as all boards, including the one the starhub module is mounted on, are connected to the starhub with cables of the same length.
  • Page 77 Therefore it is possible to exclude a board from the triggerbus so that only a synchronization for clock is done and the ac- cording boards are just using the trigger events they have detected on their own. Register Value Direction Description SPC_NOTRIGSYNC 200040 If activated the dedicated board will use its own trigger modes instead of the synchronization trigger. (c) Spectrum GmbH...
  • Page 78 The setup order for the different synchronization options Synchronization (Option) Even if a board is not using the synchronization trigger, it before must be set as a triggerslave with the SPC_SYNCTRIGGERSLAVE command. After you have excluded one or more of the installed boards from the synchronization trigger it is possible to change the triggermodes of these boards.
