Description
CenterFreqTimeo Tango::DEV_ULONG This sets the time the server should wait to let the instrument setup the center frequency and the span frequency. In milliseconds. Default:600ms.
PeakTimeo Tango::DEV_ULONG This sets the time that the server should wait for the peak to be found. Default: 600ms
InitTimeo Tango::DEV_ULONG Time to wait for init to be completed. Default 400ms.
AlwaysExecTimeo Tango::DEV_ULONG Always executed hook timeout. This timeout is applied inside the so called 'always executed' actions.
StartStopTimeo Tango::DEV_ULONG Sets the time to wait for the instrument to set start and stop frequency. A 'set start frequency' is imparted, then a 'set stop frequency'. After those we sleep for StartStopTimeo milliseconds.
Frf Tango::DEV_DOUBLE RF fundamental frequency, in MHz. This is given as a class property to augment the flexibility of the device administration.
Frev Tango::DEV_DOUBLE Revolution Frequency of the synchrotron, in MHz
Window Tango::DEV_DOUBLE Window inside which peaks are searched, in kHz.
Span Tango::DEV_DOUBLE Span amplitude of the instrument, in kHz.
Fs Tango::DEV_DOUBLE Synchrotron Frequency, in kHz
WindowFs Tango::DEV_DOUBLE Window around synchrotron frequency for peak search. The peak search is intended to take place around synchrotron frequency - window_fs and synchrotron frequency + window_fs.
MaxBunches Tango::DEV_ULONG Maximum number of bunches to measure.
PeakTableTimeout Tango::DEV_ULONG Time after getting peak tables. This instrument has the capability to catch all peaks inside the span interval with this single command and return them in a table. After we have got a peak table, we wait PeakTableTimeout ms before performing another shot.
SweepsNo Tango::DEV_ULONG Number of sweeps, i.e. the number of traces for a measurement. This command is not available on this instrument.
MinFundamentalPeak Tango::DEV_DOUBLE Minimum value over which the amplitude of the rf frequency must stay.
SetSpanTimeo Tango::DEV_ULONG Time to wait after we set the instrument span frequency.
