Time Tagging:
IRIG B Time Tag
For absolute time tagging, a special time code processor
implements an IRIG-B encoder/decoder. If no external IRIG-B
source is available a time code in IRIG B format is generated
and can be used to synchronize multiple boards or modules.
Decoder:
Format:
IRIG-B-122
Resolution: 1 µs
Width: 1 Year (46 Bit)
Signal Waveform: Amplitude modulated sine wave or square
wave
Modulation Ratio: 3:1 to 6:1
Input Amplitude: 0.6Vp-p to 5Vp-p
Input Impedance: ~10k ohm
Coupling: AC coupled
Time Jitter: +/-5µs (depending on the ip-signal quality)
Lock time: < 5s
Free-wheeling accuracy after 10 Minutes < 1ppm (assuming
input signal accuracy better than 50ppm)
Encoder:
Format:
IRIG-B-122
Absolute Accuracy: +/-25ppm (standard Oscillator)
Signal Waveform: Amplitude modulated sine wave
Output Amplitude: ~4.5 Vp-p, High voltage level
Output Impedance: ~51Ohm
Coupling:
AC coupled
Modulation Ratio: ~ 3:1
Carrier Frequency: 1 kHz +/-50ppm
Line
Transmitter:
Transmitter channel Output Impedance 75Ω
All TX Channel with fixed output amplitude from 0 to ±11V
High/Low Speed: Rise and Fall time automatically switched via
Analogue Switches to meet the requirement for High / Low
Speed operation
