OSA 86146B problems

Question asked by john01 on Jan 25, 2016
I have a 86146B OSA that seems to work but very, very slowly. At start "Self Test" 1, 2, 3 lasts 15-20 minutes. "Preliminary Tests Passed" message appears after another 80-90 minutes. Final initialization after 20-30 minutes. Do not show any error message, but it takes about 2 hours all the initialization process. Then when you finally use the device for measurements to process an order/ a command (e.g by pressing a button such as "Amplitude", "Wavelength") takes 2-3 minutes. How to troubleshoot the device to function normally and these delays do not exist?
