Pulsed NMR probe‐monitoring system

A simple device for measuring the instantaneous reflected power from a NMR probe is described. It is built from commercially available directional power‐meter components coupled to a low‐speed oscilloscope. The device can be used to monitor the performance of a probe while data are being acquired. I...

Zusammenfassung:	A simple device for measuring the instantaneous reflected power from a NMR probe is described. It is built from commercially available directional power‐meter components coupled to a low‐speed oscilloscope. The device can be used to monitor the performance of a probe while data are being acquired. It is particularly useful for adjusting probes whose characteristics change during a high‐power pulse because of component heating.
