Daedalus Lock Manual

Display mode
14.0.11
This is the same function as menupoint 2.4 Display Mode in the lockmenu on key-
board. The lock can display different signals like 0 real part, 1 real part low pass fil-
tered, 2 imaginary part, 3 controller out, 4 real part expanded (8-times sensitiver
than normal real display, sensational for fine shimming), 5 real part expanded low
pass filtered, 6 FFA Spectrum, 7 Controller out expanded. Default value is 0 real.
Read Lock Level
14.0.12
This function allows you to read either the MX(0) or MY(1) value.
Lock Shift
14.0.13
This function allows you to work with any desirable lock frequencies. The lock 2H
transmitter frequency is generated by mixing a multiple of 10MHz and the DDS fre-
quency, the 19F frequency by mixing a multiple of 10MHz, the DDS freq. and the
PPL freq.(a multiple of 1MHz). The Controller can load the DDS with frequencies
up to 20 MHz. The menu Lock Shift has four subfunctions, ‘W’ write a new
shift(like the Lock Shift parameter on keyboard), if you want to work with this then
the ’Autolock Mode’ (see above) must first be set to ’Shift’. ‘R’ read the current
Lock Shift parameter (like the Lock Shift parameter on keyboard), ‘G’ read the DDS
frequency and display it in Hz, ‘O’ write a new DDS frequency (in Hz).
Writing a new DDS Frequency (‘O’) changes the default DDS value and also the
frequency variation caused by ‘Lock Shift’.(1ppm => (defaultfreq / 1E+06))
Examples 1: Locked with CFCl3 as lock compound. New sample has C6F6 as lock
compound. Refer to 19F chemical shift table referenced to CFCl3.
δ
/ppm for C6F6 is -163 => New Lock Shift is -163ppm(‘W’ 163000).
Example 2: Your 500 Mhz Magnet is 40KHz @ 2H below the standard field. The
new 2H default lock frequency is calculated with freq = f2H - 40KHz
Refer to Appendix Deuterium or Fluorine Frequency Generation in this manual.
f2H for a 500MHz Instrument = 76.774386MHz.
76.774386MHz - 40KHz = 76.734386MHz
Frequency Generation for a 500MHz Instrument: 90MHz - freqDDS(mind the sign!)
New default DDS frequency is 90MHz - 76.734386MHz = 13.265614MHz
Enter 13265614 as new default DDS frequency(‘O’). Remind that 1ppm (Lock
Shift) changes from 76.774386Hz to 76.768244Hz. Save this new configuration
with Save Config. in the keyboard service menu. Your lock system is now working
as if it was a regular 500MHz system in 2H and 19F applications.
After every BSMS powerup or reset a warning (Caution Lock Frequency) will in-
form you about your unusual lock frequency.
Example 3: Setting the default 2H frequency for all magnets.
Lock Menu => 5. Lock Substance (w)rite (0) Deuterium. The default frequency is
now set as in Appendix table Deuterium Frequency Generation. Save this configura-
tion with Save Config. in the keyboard service menu.
