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 |
