-If configured as OUTPUT (see in Capture software as below,
Type ≠ “1-axis encoder +increment”)
-TTL 5V
-= PRF = 5V/100ns pulse generated with each Pulser signal (IPEX
connector).
-Signal can be used to synchronize an external system
-Jitter = 10ns.
-Absolute Max output current +/-50 mA
-If configured as INPUT (see in Capture software as below,
Type = “1-axis encoder +increment”)
-TTL 5V, active on High level
-Max Input current 50µA
-When connected to Phased Array Wheel probe, Synchro1 is used as
« Index Increment » (short press) and « Scan Encoder Reset » (long
press > 2sec).
