Description |
| BPMDevice |
Tango::DEV_STRING |
The name of the dedicated BPM device server |
| BPMPosVectorAttributeName |
Tango::DEV_STRING |
The name of the BPM attribute on which the tune measure is done.
Should be something like XPosVector or ZPosVector |
| BPMNumSamplesAttributeName |
Tango::DEV_STRING |
The name of the Attribute corresponding to the number of samples contained
in a BPM position vector. |
| SkippedFirstSamples |
Tango::DEV_USHORT |
The number of samples that are dropped in the beginning of the BPM buffer, before computing the FFT |
| WindowType |
Tango::DEV_STRING |
The type of window applied to the input signal. Must be one of the following : RECTANGULAR, BLACKMAN, EXACT_BLACKMAN, HAMMING, HANN, FLATTOP, BLACKMAN_HARRIS_3, BLACKMAN_HARRIS_4, BLACKMAN_HARRIS_7, LOW_SIDELOBE |
| FFTMinimalNbPoints |
Tango::DEV_LONG |
The minimal number of bins in the FFT.
Must be a power of 2 (otherwise, rounded to the next power of 2 |
| ComputationPeriod |
Tango::DEV_LONG |
The initial internal period in millisecond at which new tune measures are produced.
At each period, a new data buffer is read from the associated BPM and a new tune measure is produced. |
| AutoStart |
Tango::DEV_BOOLEAN |
if set to 'true', the computation of the tune measure starts automatically when the device is launched |
| FFTWindowSize |
Tango::DEV_LONG |
The number of points in the BPM buffer that are used to compute the FFT |
| WriteNumSamplesAtStartup |
Tango::DEV_BOOLEAN |
When used on top of the Tranverse Feedback system, the device does not try to
write the data buffer size at startup. In this case it just read the buffer size on
the specified device. |
