rixx43518 run 327 is a short run taken with the Andor running at 120Hz in 90x90 crop mode.  Here is an image from AMI:

Rate Measurements in Crop Mode

(from Dan Damiani)

FVB works at 120 Hz with both the 3Mhz and 1Mhz readout mode. This isn’t new. We have used the 1Mhz readout mode with full vertical binning in SXR in previous experiments, so it isn’t surprising that this still works.

For crop mode it is slightly more complicated.

Note there is a PV you can use to check if the settings you have chosen will work for a particular trigger rate:

RIX:DIR:CAM:01:AcquirePeriod_RBV

This is just a time in seconds. So for example if set the camera to 1Mhz readout, crop mode, and 50x50 roi I get this:

caget RIX:DIR:CAM:01:AcquirePeriod_RBV

RIX:DIR:CAM:01:AcquirePeriod_RBV 0.00831

That number needs to be less than 1/trigger rate in order for things to work, and this is slightly less than 1/120.

Working from this you get (rounding to the nearest multiple of 5 works):

Miscellaneous Thoughts on running the Newton Camera

Out[6]: psana.Andor.EnumCropMode.ENUM_CROP_ON

In [7]: andorconfig.baselineClamp()
Out[7]: 1

We don't think the baselineClamp setting matters, but the IOC does have a different default setting of 0.
