Scope

Scope#

class Scope(resourceName, name)#

Bases: Hardware

Scope abstract base for oscilloscopes.

Provides common acquisition timing (Duration, NSample), trigger configuration (TriggerMode, TriggerSource, TriggerSlope, TriggerLevel), measurement helpers (peak-to-peak, extrema, mean, RMS, std), and sine-fit quantities (SineAmplitude, SineFrequency, SinePhase, SineOffset). Concrete subclasses implement vendor-specific connections and I/O.

Example:

sc = Tektronix1104("USB0::...", name="Scope");
sc.connect();
sc.Duration = 0.01; sc.NSample = 2500; sc.IsEnabled = [true true false false];
sc.set();
sc.read();
sc.plot();
