class baseband.gsb.base.GSBStreamBase(fh_ts, fh_raw, header0, sample_rate=None, samples_per_frame=None, payload_nbytes=None, nchan=None, bps=None, complex_data=None, **kwargs)[source] [edit on github]

Bases: StreamBase

Base for GSB streams.

Attributes Summary

bps

Bits per elementary sample.

complex_data

Whether the data are complex.

header0

First header of the file.

payload_nbytes

Number of bytes per payload, divided by the number of raw files.

sample_rate

Number of complete samples per second.

sample_shape

Shape of a complete sample (possibly subset or squeezed).

samples_per_frame

Number of complete samples per frame.

squeeze

Whether data arrays have dimensions with length unity removed.

start_time

Start time of the file.

time

Time of the sample pointer's current offset in file.

Methods Summary

close()

tell([unit])

Current offset in the file.

Attributes Documentation

bps

Bits per elementary sample.

complex_data

Whether the data are complex.

header0

First header of the file.

payload_nbytes

Number of bytes per payload, divided by the number of raw files.

sample_rate

Number of complete samples per second.

sample_shape

Shape of a complete sample (possibly subset or squeezed).

samples_per_frame

Number of complete samples per frame.

squeeze

Whether data arrays have dimensions with length unity removed.

If True, data read out has such dimensions removed, and data passed in for writing has them inserted.

start_time

Start time of the file.

See also time for the time of the sample pointer’s current offset.

time

Time of the sample pointer’s current offset in file.

See also start_time for the start time of the file.

Methods Documentation

close()[source] [edit on github]
tell(unit=None) [edit on github]

Current offset in the file.

Parameters:
unitUnit or str, optional

Time unit the offset should be returned in. By default, no unit is used, i.e., an integer enumerating samples is returned. For the special string ‘time’, the absolute time is calculated.

Returns:
offsetint, Quantity, or Time

Offset in current file (or time at current position).
