bin5000(w: Any, channel_number: int) → None[source]: Interpret normalized waveform data for Rigol MSO5000 .bin files.

calc_times_and_volts(sample_aligned: bool = False, memory_depth_points: int | None = None, midpoint: float = 127.0) → None[source]: Calculate the times and voltages for this channel.

dho1000(w: Any, channel_number: int) → None[source]: Interpret normalized waveform data for the Rigol DHO800/DHO1000 series.

ds1000b(w: Any, channel_number: int) → None[source]: Interpret waveform data for 1000B series scopes.

ds1000c(w: Any, channel_number: int) → None[source]: Interpret waveform data for 1000CD series scopes.

ds1000d(w: Any, channel_number: int) → None[source]

Interpret waveform data for 1000D series scopes (uses wfm1000e parser).

DS1000D firmware stores scale_measured already probe-corrected, so the probe_value factor that wfm1000e bakes into volt_scale must be divided out.

ds1000e(w: Any, channel_number: int) → None[source]: Interpret waveform data for 1000D and 1000E series scopes.

ds1000z(w: Any, channel_number: int) → None[source]: Interpret waveform for the Rigol DS1000Z series.

ds2000(w: Any, channel_number: int) → None[source]: Interpret waveform for the Rigol DS2000 series.

ds4000(w: Any, channel_number: int) → None[source]: Interpret waveform for the Rigol DS4000 series.

ds6000(w: Any, channel_number: int) → None[source]: Interpret waveform for the Rigol DS6000 series.

lecroy(w: Any, channel_number: int) → None[source]: Interpret normalized waveform data for a LeCroy .trc file.

rohde_schwarz(w: Any, channel_number: int) → None[source]: Interpret normalized waveform data for a Rohde & Schwarz RTP .bin file.

siglent(w: Any, channel_number: int) → None[source]: Interpret normalized waveform data for a Siglent .bin file.

tek(w: Any, channel_number: int) → None[source]: Interpret normalized waveform data for a Tektronix .wfm file.

trim(duration: float) → None[source]

Trim the data arrays to a window of duration around time_offset.

Parameters:: duration – length of the window to keep, in seconds.

trim_to(start: float, end: float) → None[source]

Keep only the samples between start and end, inclusive.

Parameters:

start – first time to keep, in seconds.
end – last time to keep, in seconds.

trim_window(duration: float) → tuple[float, float] | None[source]

Return the time window of duration this channel would keep.

The window is centered on time_offset, the point the scope was displaying, and slid back inside the record if that would run off either end. A duration longer than the record keeps everything.

Parameters:: duration – length of the window in seconds.
Returns:: The (start, end) times, or None when there is nothing to trim.

yokogawa(w: Any, channel_number: int) → None[source]: Interpret normalized waveform data for a Yokogawa .wfm file.
