XHz Timing Signal Generator The Hammers Company provides a signal generator to support synchronization of our spacecraft simulator capabilities for VirtualSat® and Galaxy® spacecraft simulators using Mil-Std 1553 or SpaceWire data interface technologies. The XHZ timing signal generator is a multifunction instrument. It provides Low Voltage Differential Signal (LVDS), RS-422 Differential Signal, RS-232 Single-End Signal, and TTL Logic Interface. The output frequency is selectable from 1Hz, 2Hz, 4Hz, 5Hz, 8Hz, 10Hz, or external signal pulse. The optional duty cycle is 1%, 10%, 20%, or 50%. The other duty cycle options are 80%, 90%, or 99% generated by the signal output polarity control. The XHz card has two power options; using USB as a power source alone, or using an external power adapter (+9VDC – +12VDC, 1 AMP). External ground connection is also provided. CONTACT US
