The Keysight 80W, single output E3644A is a stable and reliable power supply for benchtop and basic automated test applications, and enables versatile solutions for tests that require moderate speed and precision with both GPIB and RS232.
The Keysight E3644A is a high performance benchtop optical spectrum analyzer with a filter mode that provides the flexibility to drop a single DWDM channel with fast-tuning speed, low-insertion loss, and highly repeatable wavelength accuracy.
Another application of the filter mode is to measure time-resolved chirp (TRC). Using the filter with a 86100C DCA, chirp measurements can be made on lasers.
