Operation Hours and Power-on event counters at delivery of new singal generators


How many operation hours and power-on events are already on new singal generators when they get delivered to customers? How can operation hours and power-on event counters are retrieved from most signal generators?


During the production process new generators will be tested and calibrated. This results that the Operation Time Counter shows already upto 200 hours and the Power-On Counter upto 250 cycles at delivery.

The command queries the number of operation hours

The command queries the number of power-on events
