The 2250 calibrates itself. At turn-on or frequency change, the instrument automatically initiates a self-calibration sequence. This checks critical performance criteria and makes internal adjustments that maximize accuracy. This sequence can be initiated by the user at any time. Long term accuracy and stability is thus assured.
