5 .2 About Trombone Calibration
The electromechanical trombone offers a range of delay from 0 to 625.0 ps with a step resolution to 0.50 ps per step. For each of
the 1251 delay settings from 0 to 625.0 ps at 0.50 ps steps, a calibration compensation table entry is created at time of instrument
manufacture and stored into non-volatile memory. When enabled, every delay setting will apply the calibration compensation to the
motor movement position commands to ensure positional accuracy is applied. The CTSTORE command is used to enable (on) or disable
(off) the use of this calibration table. The CTSTOREM command is used to download the calibration table to the instrument. In normal
usage, there is no need to download or update the calibration table. There are no end user calibration measurements or compensations
that can be applied. The CTSTORE? query will return the current status or information about specific entries in the calibration table or
information regarding this table.
