1 PPS
The SF-2050M has the ability to output a precise pulse
every second that can be used for a variety of Time/
Mark applications where precise timing is critical.
Specifications:
- 12.5ns relative accuracy.
- Better than 100ns absolute accuracy.
- 50 Ohm, TTL level.
- Pulse width, default 100mS, range 10 – 999mS
- Pulse delay, default 0mS, range 0 – 999mS.
- Rising or Falling Edge Synchronization.
Connecting the 1
PPS
output requires a cable with a
BNC male connector, NavCom
P/N
94-310050-3003
0.9m (3ft) long, BNC male to BNC male cable.
CAN Bus/Event
The SF-2050M also employs a balanced (differential) 2-
wire
CAN Bus
technology interface, ISO11898 -24V
compliant. The
CAN
interface uses an asynchronous
transmission scheme employing serial binary
interchange and is widely used in the automotive
industry. The data rate is defined as 250K
bps
maximum
with Termination resistors used at each end of the
cable. This port/connector is shared with the
Even
t
Input.
