Alarm Monitoring Item |
Power failure | The DC power supply input in two methods is observed after the diode synthesizing, and warning is output when the voltage decreases to +36V or less. |
10MHz inputLevel down | The level decrease in 10MHz input in two methods is independently observed, and warning is output when decreasing to -4dBm or less. | |
1PPS pulseInput detect | Warning is output when the 1PPS pulse input cannot be detected as TTL level (VIL:0.8V or more, VIH:2.0V or less). | |
1PPS pulseLevel down | Warning is output when any 1PPS pulse output without monitor output cannot be detected as TTL level (VIL:0.8V or more, VIH:2.0V or less). |
