TraRecord

class vallenae.io.TraRecord(time, channel, param_id, pretrigger, threshold, samplerate, samples, data, status=<HitFlags: 0>, trai=None, rms=None, raw=False)

Transient data record in tradb.

__init__(time, channel, param_id, pretrigger, threshold, samplerate, samples, data, status=<HitFlags: 0>, trai=None, rms=None, raw=False)

Methods

__init__(time, channel, param_id, ...[, ...])
from_sql(row, *[, raw])	Create TraRecord from SQL row.

Attributes

raw	data is stored as ADC values (int16)
rms	RMS of the noise before the hit
status	Status flags
trai	Transient recorder index (foreign key between pridb and tradb)
time	Time in seconds
channel	Channel number
param_id	Parameter ID of table tr_params for ADC value conversion
pretrigger	Pretrigger samples
threshold	Threshold amplitude in volts
samplerate	Samplerate in Hz
samples	Number of samples
data	Transient signal in volts or ADC values if raw = True
