Trimble MS750 Dual Frequency RTK Receiver. Attached is my current working configuration using phase buildout settings.Details. All outputs appear stable relative to their references, but not phase aligned. A 1pps output which has the short term stability of the rubidium/ OCXO ( jitter 2hrs. Supports operating temperatures from -25☌ ~ +75☌ More.
GPS-721 GPS Receiver and 1 DO, 1 PPS Output Module communicable over RS-232 and RS-485. 1.PPS, there is a second pulse output after positioning, the pulse period is 1s, and the high level lasts for 100ms, which is used for system synchronization. GPS Enable ( yellow wire) -> USB Module VCC pin. GPS +5 Volt Power (red wire) -> USB Module VCC pin. GPS Ground (black wire) -> USB Module Ground.
GPS Receive Input (green wire) -> USB Module TXD pin. GPS Transmit Output (blue wire) -> USB Module RXD pin. The 1PPS output is accurate within USB Module DCD pin. For timing, synchronization and time keeping, the unit provides optional NTP(v4), in addition to the standard 1PPS and IRIG B outputs. Additional options for selectable output clock frequencies are also available. 100kHz, 1MHz, and 5MHz), 1PPS and IRIG B(am) outputs. Option modules include our Universal Card, Code. With 4 option module slots, and up to 4 user-configured outputs per module, Trestles is adaptable to many different applications.
