Description

OUTPUT 723;"TRNSZLOCK;"

The TRNSZLOCK command locks the optical spectrum analyzer's internal transimpedance ampli￿er.

Locking the transimpedance ampli￿er limits its range to ensure wide bandwidth and fast settling characteristics. This allows the optical spectrum analyzer to make accurate fast pulse measurements. Using the INSTMODE PULSE command automatically locks the transimpedance ampli￿er.

Normally, the transimpedance ampli￿er is unlocked, and the full transimpedance range of 1 k￿ to 100 M￿ is available. However, when locking is selected, the ampli￿er is limited to the 1 k￿ and 10 k￿ values.
