Measuring at one Frequency. For this measurement setting in the main Window the start frequency is used for the sequence. Additionally the frequency step must be set to 1.

Implemented sequence types

  • FID sequence
  • Spin-Echo sequence
  • Composite pulse sequence
  • Spin echo phase sequence

getting started

Select the intended sequence in the main window. A new window will be opened to select the parameters of the selected sequence type. With saving the entered parameters all parameters will be updated in the sequence file ready for the experiment execution when RUN is pressed.

Info to the sequenc,

The following sequence are implemented with its predefined parameters.

FID sequence

For this sequence a 90° pulse gets generated.

Spin-Echo sequence

For this sequence a 90° following a 180° pulse gets generated.

Composite pulse sequence

A Pulse sequence which changes its phase with time, i.e. undergoes phase modulation. It is used for suppressing coil ringdown and other artefacts synchronous to the RF-pulse.

Spin echo phase sequence

For this sequence a 90° following a 180° pulse gets generated. Additionally the second pulse gets transmitted with different phase shifts.
