About PhasorZ
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.
