Bench tools for circuits — impedance calculator and signal generator.

Impedance Network Build passive RLC networks in series or parallel and see the total impedance instantly in both rectangular and polar form. - Build resistor, inductor, and capacitor networks in series or parallel - Enter values using engineering notation: `4.7k`, `10u`, `22n`, `100m` - View impedance in rectangular form: `R + jX Ω` - View impedance in polar form: `magnitude ∠ angle°` - System frequency locks after the first component so reactances stay consistent - Correct sign conventions for resistors, inductors, and capacitors - Instant total impedance calculation without matrix arithmetic - No tab switching or physical calculator needed mid-lab Signal Bench A virtual function generator connected to a two-channel oscilloscope. Opens in a full tab. - Four waveform shapes: sine, square, triangle, and ramp - Adjustable frequency from `1 Hz – 1 MHz` - Adjustable amplitude and DC offset - Adjustable duty cycle - Live measurements for: - Vpp - Vrms - Vavg - Vmax - Vmin - Period - Vrms and Vavg are calculated by numerically integrating over one complete period - Fully accounts for duty cycle and DC offset — no formula shortcuts that break on non-sine waveforms - Second channel with adjustable phase for visualising phase relationships - Scope-style `time/div` and `volts/div` controls - 1-2-5 step scaling - Automatic oscilloscope scaling Why It Exists Because verifying homework at 11pm shouldn't require booting a full SPICE simulator. And `Vpp/(2√2)` doesn't cut it once you add a DC offset.
