8.14.3 Sync recording operation
For sync recording of Q camera, you can use the following external input signals.
Page 8-24 table 1 shows sync settings for using each external input signals.
Please refer to
1 Nothing of external signals
-use nothing of external signals
2 Use EST signals
-perform sync recording by inputting EST signals into SYNC IN
The maximum frame rate when using of EST signals is less 1/2 of the maximum frame rate of
camera specification.
3 Use periodic sync signals
-perform sync recording by inputting periodical signals into SYNC IN
※
If you input lower frequency signals than frame rate setting, starting exposure and exposure
time shift from setting.
※
Not input higher frequency signals than frame rate setting.
4 Use 1kHz sync signals
-perform sync recording by inputting 1kHz signals into SYNC IN
You can record at frame rate which is Multiple of 1,000 pps.
※
1kHz signals requires time accuracy within ± 200 ns per cycle.
5 Use IRIG signals
- perform sync recording by inputting IRIG signals into SYNC IN
※
When you input IRIG signals directly into Q camera, signal standard is IRIG(DCLS).
Please be careful to not input other signals.
6 Use Q-HUB without external signals
-perform sync recording of Q camera by using Q-HUB as standard without other external
signals.
Refer to Q-HUB User’s Manual for details about operation method of Q-HUB.
In case that input external signals into Q-HUB
Switch EST / IRIG of Q-HUB switch according to external signals, as shown below.
EST signals
Switch EST.
1kHz signals Switch IRIG.
In this case, set recording settings of Q camera according to “5 Use IRIG signals”
Period signals Switch EST.
IRIG signals Switch IRIG.
Above operation methods can use daisy-chain connection to sync record.
