Transistor pair
Independent two-channel analyzer. Assign Vin1 and Vin2; Vstat is not used. Available in DSView's Пользовательские section as Transistor pair.
- Minimum active ON pulse duration (mintime), independently per input.
- Minimum inactive OFF duration, independently per input.
- Deadtime from Vin1 OFF to Vin2 ON and vice versa, with independent minimums.
- Active overlap is a fault, regardless of the deadtime settings.
- Period, frequency and active duty cycle for complete cycles on each input.
- Independent active-high/active-low polarity for both inputs.
All limits are nanoseconds. Zero disables the corresponding lower limit; equality passes. Simultaneous handovers measure zero deadtime. These settings check measured pulses and do not debounce or filter the source waveform.
Measurements occupy separate waveform rows. Timing violations appear in the FAULT row. Unknown edges outside the capture are not fabricated; partial pulses do not produce full pulse widths or full-cycle frequency/duty values.
Python: PairTimingChecker in logic_analyzer.decoders.transistor_pair.
Offline API: analyze_capture(..., dict(mode='Transistor pair', channel=0, vin2_channel=1, vin1_mintime_ns=100, deadtime_12_ns=50)).
For Vin/Vstat ACK checks and full driver-cycle OK/WARNING/FAULT results use the separate IGBT 1SP/1SD decoder.
