IRIG A/B (IEEE1344,
C37.118, AFNOR) receiver and IRIG-A/B/G (IEEE1344, C37.118, AFNOR) generator
slot card with the following features:
IRIG receiver with TCXO Oszillator (optional: OCXO LQ/MQ/HQ)
Single lane (x1) PCI Express (PCIe) Interface, PCI Express r1.0a
compatible (Gen1, 2.5 Gbps)
1 x modulated IRIG A/B (IEEE1344, C37.118, AFNOR) input, input impedance
default 600Ohm
(settable 50, 600 or 5000 ohm), via
isolated female BNC connector
1 x unmodulated (DC level shift) IRIG A/B/G (IEEE1344, C37.118, AFNOR) input,
isolated by photocoupler, on
the 9pin D-Sub male connector of the Multiref port
1 x modulated IRIG-A/B/G (IEEE1344, C37.118, AFNOR) output (3Vpp/1Vpp into 50
Ohm), via isolated BNC connector
Standard Port (Standard via the 9-pin SUB-D)
1 x RS232 interface COM0, 9pin D-Sub male connector
3 x pulse outputs, TTL, free programmable with pulses, switching times,
frequency synthesizer or Time Code
preset to:
PPO0: pulse per second (PPS), active high,
pulse duration 200msec
PPO1: pulse per minute (PPM), active high,
pulse duration 200msec
PPO2: DCF77 compatible pulses, TTL, active
high
1 x pulse outputs, TTL, free programmable with pulses, switching times,
frequency synthesizer or Time Code
preset to:
PPO0: pulse per second (PPS), pulse
duration 200msec
2 x time capture input, TTL
1 x 10MHz standard frequency, TTL
1 x Time Code unmodulated (DCLS), IRIG-A/BG ( IEEE1344, C37.118, AFNOR) Output,
RS422
Multiref Port (optional)
To use the multiref port inputs/outputs, this should be connected to a 9-pin
SUB-D connector
For this the available SUB-D connector can be used. If the Standard Port and
the Multiref Port is needed a SUB-D on a extension slot is required
1 x PPS Input, TTL
1 x RS-232 interface COM1, 9pin D-Sub male connector
2 x pulse outputs, TTL, free programmable with pulses, switching times,
frequency synthesizer or Time Code
preset to:
PPO0: pulse per second (PPS), active high,
pulse duration 200msec
PPO1: pulse per minute (PPM), active high,
pulse duration 200msec
1 x 10MHz standard frequency, TTL
1 x synthesizer for frequencies from 0,1Hz up to 10MHz, TTL and sine wave
(1.5Veff into 200 Ohm)
1 x unmodulated (DC level shift) IRIG-A/B/G (IEEE1344, C37.118 AFNOR) output,
TTL into 50Ohm
1 x unmodulated (DC level shift) IRIG A/B (IEEE1344, C37.118, AFNOR) input,
isolated by photocoupler.
4 x status LEDs
