MNS exciter calibration

The nuclei that are calibrated by default are 13C and 31P. To guarantee a linear output from the MNS exciter at other frequencies, you can edit a config file to specify which other frequency or frequencies that the site needs calibrated. This config file controls which MNS frequencies are used when calibrating the transmit gain tables of the MNS exciter. To choose frequencies to calibrate, open the config file and change the value for the desired frequencies from 0 to 1. The calibration happens during the next TPS reset or system restart. This calibration uses the loopback path only. No RF is sent to the broadband amp. The system only needs to be configured for MNS with the standard MNS hardware (exciter, cabling, etc.). It is not necessary to connect an MNS TR module during this calibration.

Procedure

  1. note: Each additional frequency calibration will add time to the TPS reset. Calibrate only the nuclei that the site needs; do not calibrate them all.
    In a C shell, go to the directory /w/config
  2. Type gedit mnsTgCal.cfgEnter
    The mnsTgCal.cfg file contains a list of available nuclei.
  3. For the nuclei that the site needs calibrated, change the value from 0 to 1.
  4. Save the file.
  5. Type more mnsTgCal.cfgEnter and confirm that the changes were saved.
    At the next TPS reset or system restart, the nuclei will be calibrated.
