PXI – Drift Stabilizer DS PU DS MS PU MS PFL TX Line Trig Amp DS Trigger + offset MS Trigger + offset Thyratron Drift Stabilizer : Compensate for drift inside Trigger Amplifier and Thyratron, by measuring the time between the rising edge of DS/MS I+ and the DS/MS trigger. By adjusting the offset the drift can be compensated, an interlock is activated if the drift becomes significant Resolution 1 ns, obtained with high resolution digitizer LOAD Magnet
