SPEC_fltw_move
// Purpose : Change filter wheel in spectroscopy // Attention: there is only one controller for // the filter wheels and the grating, but different // sets of controller parameters! // // CUS script : Diego A. Cesarsky // // Description : This script will change the spectrometer filter // into a specified position. This can be a predefined // position (with mode = 'ABS') or a relative position // (with mode = 'REL'). // // This script performs the following operations (section // 4.4.8 of the DEC/MEC User's Manual): // "Consider that the grating is powered on and that an // acquisition sequence has ended. To change the filter wheel // position now: // 1. Disable the grating controller (DMC_DISABLE_GRAT_CONT) // 2. Switch-on the spectro filter wheel controller // (DMC_SWON_FW_SPEC). Note : this will switch-off the // grating controller and the photo filter wheel controller // but the grating position encoder will remain powered-on // and will then continue reading the position. // 3. Any of the 2 move commands can be sent // 4. Switch-on the grating controller (DMC_SWON_GRAT_CONT) // 5. Enable the grating controller (DMC_ENABLE_GRAT_CONT) // 6. Start the new acquisition sequence." // // NOTE: THIS SCRIPT IGNORES REL MODES // // Comments : This script should be executed after the // switch-on procedure and the MEC setup // // Version : 0.1 11-Oct-2004 Creation by DAC, based on TM's // V1.1 of tm_spec_fil_switch.tcl // History : 0.2 18-Oct-2004 Normalized variable names // 0.3 22-apr-2005 DAC Converted into procedure // Removed useless delays, read move time // from PACSparams // :
