5. Run the singlepulse_nmr_example.bat file by double-clicking. Once the singlepulse_nmr.bat file has
completed, three new files (*.fid, *.jdx, *.txt) will be created in the directory from which the batch file
was executed.
6. Open the Felix file (.fid) in Felix for Windows, or open the .jdx file in any program that supports
JCAMP-DX. An easily parsed text file containing the NMR data will also be generated. For information
on installing and using Felix to view your .fid files, go to

Figure 7:
General timing diagram of the basic single-pulse sequence (not to scale). A single scan is
performed as follows: A blanking TTL pulse is applied to allow for RF Power Amplifier warm-up (Blanking
Delay), a single RF pulse is applied to the sample for a specified amount of time (Pulse Time). The high
voltage induced on the sample coil is allowed to ring down (Transient Time), after which the Free Induction
Decay (FID) signal is acquired (for length Acquisition time). The sample is then allowed to relax for a time
(Repetition Delay). This scan procedure is then repeated an arbitrary number of times as desired to improve
the signal to noise ratio.
