Class Description

                     The LScope  Class
                    ===================
  This class was created to be used with the oscilloscope LeCroy LT-344
  but with minimal changes of commands, it could be used to any gpib
   device.

  Basic procedure to use this class is:
       1. create class and initialize device with LScope::Init
       2. download the state of the device with LScope::DownloadState
       3. set numper of aquisition points with LScope::SetNP
       4. set device to meassure with LScope::Arm
       5. take trace to computer with LScope::TakeTrace
       6. get trace with LScope::GetTrace

                     ============================

   -*-*-*-*-*-*-*-*-*LScope default destructor*-*-*-*-*-*-*-*-*-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*-*-*-*Set Channel on/off*-*-*-*-*-*-*-*-*-*-*-*-*-*
                     ============================
       possible values for channel are C1,C2,C3,C4 and TA,TB,TC,TD

   -*-*-*-*-*-*-*-*-*Internally used check for errors*-*-*-*-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*-*-*-*Init gpib device*-*-*-*-*-*-*-*-*-*-*-*-*-*
                 ============================
       address of device must be set!
       configuration file conffile is optional

   -*-*-*-*-*-*-*-*Internally used for Init from file*--*-*-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*-*-*-*Internally used for sending to device*-*-*-*-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*Internally used for sending to device like printf**-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*-*-*-*Internally used for receiving from device*-*-*-*-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*-*-*-*Set Number of aqusition points*-*-*-*-*-*-*-*-*
                     ============================
      If this number differs from total points set with MSIZ,
      only part of the whole signal from the scope will by transfered to
      computer.

   -*-*-*-*-*-*-*-*-*Set Time division *-*-*-*-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*-*-*-*Set device to capture*-*-*-*-*-*-*-*-*
                     ============================

   -*-*-*-*-*-*-*-*-*return array of aqusited data*-*-*-*-*-*-*-*-*
                     ============================
    This function is for getting raw data. We recommend to use
     TakeTrace and GetTrace (but not both!!)

   -*-*-*-*-*-*-*-*-*transfer aqusited data*-*-*-*-*-*-*-*-*
                     ============================
      This is the main function to transfer data from device
      source is mostly "DAT"

   -*-*-*-*-*-*-*-*-*return aqusited data*-*-*-*-*-*-*-*-*
                   ============================

   -*-*-*-*-*-*-*-*-*return histogram from transfered data*-*-*-*-*-*-*-*-*
                  ============================
     Take care, that histograms can't contain 250K points!!

printf("%s:VDIV %f %dn",channel,fScopeState->fVDIV[fScopeState->GetChanId(channel)],fScopeState->GetChanId("C2"));
fScopeState->PrintIt();
