Mechanical Counter

This feature keeps track of mechanical attenuator and switch changes. The firmware increments counters each time commands to change the attenuator or switch settings are sent. The dialog reads back the counters and allows a technician to reset the counters if the hardware components are replaced. This feature exists on all PNAs running firmware A.13.60 and above. There are no user SCPI commands to read these counter values remotely.
