Acquis.ini File

The initialization file acquis.ini contains definition sections for each transient recorder. The data here corresponds to the values set while configuring the transient recorders. The data entries may appear in a different order within a section named [TR<address>]. Here, the section for the transient recorder with the device address 0 is shown

A section always begins with [TR<n>] where n indicates the address of the transient recorder.

  • Rangeinput range of the transient recorder. Valid values are
    • 0 : 0 .. 500 mV

    • 1 : 0 .. 100 mV

    • 2 : 0 .. 20 mV

  • FreqDividerSet the frequency divider, it changes the sampling rate before

    the summation, so with FreqDivider value of 0 and bin width 3.75m you will get 3.75m range resolution. With a FreqDivider of 8 you will get 30m range resolution. Valid values are 0, 1, 2 ,4, 8, 16, 32, 64, 128.

  • ShotLimitSets the maximum number of shots that the TR should acquire.

    valid values are arbitrary number between 2 and 64K

  • Discriminator : level between 0 and 63

  • Pretrigger: The pretrigger is 1/16 of the hardware tracelength.

    The command can be used only if the TRHardwareInfo['HWCAP'] contains the bits 0xF9

    • 0 : disable pretrigger

    • 1 : enable pretrigger

  • ThresholdSets the damping state to either on or off
    • 0 : damping state off

    • 1 : damping state on


  • AnalogA : (TRUE | FALSE) Enable or disable analog acquisition for memory A
