IFOpen HeInterface |
Opens the 3He interface |
IFClose HeInterface |
Closes the 3He interface |
IFTalk HeInterface "He3PolEnabled()” |
Returns “1 = 3He polarizer Enabled?” if the 3He interface is initialized Returns “0 = 3He polarizer Enabled?” if the 3He interface is not initialized |
IFTalk HeInterface “He3AnaEnabled()” |
Returns “1 = 3He analyzer Enabled?” if the 3He interface is initialized Returns “0 = 3He analyzer Enabled?” if the 3He interface is not initialized |
IFTalk HeInterface “He3PolFlipOff()” |
Function flips the polarizer 3He spin to “UP” or "0" state Returns “0 = 3He polarizer state”. It does nothing if the state is already “UP” or "0" Automatically toggles back to the NMR configuration |
IFTalk HeInterface “He3PolFlipOn()” |
Function flips the polarizer 3He spin to “DOWN” or "1" state Returns “1 = 3He polarizer state”. It does nothing if the state is already “DOWN” or "1" Automatically toggles back to the NMR configuration |
IFTalk HeInterface “He3AnaFlipOff()” |
Function flips the analyzer 3He spin to “UP” or "0" state Returns “0 = 3He analyzer state”. It does nothing if the state is already “UP” or "0" Automatically toggles back to the NMR configuration |
IFTalk HeInterface “He3AnaFlipOn()” |
Function flips the analyzer 3He spin to “DOWN” or "1" state Returns “1 = 3He analyzer state”. It does nothing if the state is already “DOWN” or "1" Automatically toggles back to the NMR configuration |
IFTalk HeInterface “He3PolGetState()” |
Function returns “0 = 3He polarizer state” or “1 = 3He polarizer state” |
IFTalk HeInterface “He3AnaGetState()” |
Function returns “0 = 3He analyzer state” or “1 = 3He analyzer state” |
IFTalk HeInterface "He3PolGetNumFlips()” |
Function returns “# = actual number of flips for polarizer” |
IFTalk HeInterface "He3AnaGetNumFlips()” |
Function returns “# = actual number of flips for analyzer” |
IFTalk HeInterface “PolarizerFID()” |
Function does an FID NMR measurement for polarizer and returns a number of fit parameters Automatically tunes solenoid current to measurement value, then back for the experiment |
IFTalk HeInterface “AnalyzerFID()” |
Function does an FID NMR measurement for analyzer and returns a number of fit parameters Automatically tunes solenoid current to measurement value, then back for the experiment |
IFTalk HeInterface “FIDSetField(value)” |
Sets the solenoid current: either the FID NMR/AFP flipping measurements or the experiment Value is a number ranging from 1.5 to 5.2 A. Software and hardware limit protection is built in We do not suggest using it if not necessary. (Call us before using this command) |
