Adimec Opal 1000 | Pos | 0.0008 | 0.0002 | Pulse width affects exposure time. 0.0001 sec is too short. |
Adimec Opal 4000 | Pos | 0.0008 | 0.0002 | Maximum trigger rate is 30Hz. |
Pulnix TM-6740CL | Neg | 0.0006 | 0.0005 | Pulse width affects exposure time. |
LBL FCCD | Pos | | | Pulse width does not affect exposure time. 60 Hz strongly recommended. |
Cspad
| Neg
| 5 2.59092e5e-4 after Run Delay | 1e-5
| The integration window in the full cspad is positioned by the sum of two settings. They are the Run Delay in 119 MHz ticks and the Acq Delay in either 1.024 or 2.048 microsecond ticks. For 1.0 firmware, use 2.048 and for 1.2 or 1.5, use 1.024.
The firmware that supports the v1.5 ASICs, will use 1.024 microsecond Acq Delay ticks and introduce a fourth variable in the mix above, the Internal Trigger Delay in 125 MHz ticks.
On last sighting, the FEL was in the low 890 microseconds after the event code 140.

Cspad2x2 Version 1.5 and Daq release after 6.1.1
| Pos
| 5e-4
| 1e-5
| Run trigger the same, 5e-4 seconds, or 59524 ticks in the Daq system. For run triggers coming from controls use 58420 ticks for event code 40, since the controls triggers time from the event code, not event code 140. Start with 11020 runTriggerDelay in the configuration Scan Run Trig Delay in units of 8e-9 seconds to time in or scan across.
N.B. the above assumes a Acqdelay of 280. AcqDelay is in units of 1.024e-6 seconds and is in series with the two numbers the runTriggerDelay above.
