8. After entering the parameters, save the singlepulse_nmr_example.bat file.
9. Set your frequency source 20.000 MHz. Notice that this value is 1.0 kHz offset from the
spectrometer frequency entered in step 6.
10. Run the singlepulse_nmr_example.bat by double-clicking the file. After the scan has
completed, the program will generate three output files (rx_test.fid, rx_test.jdx, and
rx_test.txt).
11. Open the “rx_test.fid” file using Felix NMR software (available for 32-bit Windows
systems, available for download at:
http://www.spincore.com/support/RadioProcessor/Felix/Felix_Instructions.shtml ) and
verify the 1 kHz signal. After doing the FFT, you should see a strong signal at 1 kHz.
Figure 9 shows data captured by the iSpin-NMR system with a signal attenuated by over
100 dB. The time domain signal is on top (expanded) and the FFT is shown on the
bottom.

Figure 9: Data received by an iSpin-NMR system performing the Rx test. The
input signal is attenuated by over 100 dB and is less than 18 μV peak-to-peak.
