FPSC Electrical Engineer (BS-16) - AFIP
The Armed Forces Institute of Pathology (AFIP) houses high-precision clinical pathology, radiology, electron microscopy, and biomedical equipment. The Electrical Engineer (BS-16) (Case No. 118/2026) ensures uninterrupted operation, calibration, troubleshooting, and diagnostic testing of critical electro-medical systems.
Official Syllabus Breakdown
The written test conducted by FPSC is a 100-mark single-paper screening examination:
Part-I: English (20 Marks)
- Grammar Usage: Correct preposition placement, verb tenses, subject-verb agreement, modifiers.
- Sentence Structuring: Detecting structural errors, parallel construction, idiomatic expressions.
Part-II: Professional Engineering Test (80 Marks)
- DC Machines: Principles of DC generator and motor operation, back EMF, torque characteristics of series, shunt, and compound machines, and losses/efficiency.
- Power and Digital Electronics: Switching characteristics of SCR, TRIAC, MOSFET, IGBT; pulse width modulation (PWM); single-phase and three-phase uncontrolled and controlled rectifiers.
- Electric Circuits: Node voltage and mesh current methods; Superposition, Thevenin’s, Norton’s, and Maximum Power Transfer theorems; AC steady-state analysis, impedance, resonance, and power factor correction.
- Semiconductor Devices: P-N junction physics, reverse recovery time, Zener diode regulation, BJT biasing configurations (CE, CB, CC), and FET characteristics.
- Operational Amplifiers (Op-Amps): Ideal vs practical op-amp parameters, inverting/non-inverting amplifiers, summing amplifiers, integrators, differentiators, instrumentation amplifiers, and common-mode rejection ratio (CMRR).
- Oscillators & Circuit Theory: Barkhausen criterion for oscillations, RC phase shift oscillators, LC tuned oscillators (Colpitts, Hartley), and crystal-controlled stable oscillators.
- Logic Design & Switching Theory: Boolean algebra simplification, Karnaugh Maps (K-Maps), multiplexers, decoders, encoders, flip-flops (SR, JK, D, T), counters, and shift registers.
- Repairs of Multilayer Printed Circuit Boards (PCBs): Soldering/desoldering safety standards, ESD (Electrostatic Discharge) prevention protocols, trace repair, multilayer delamination identification, and surface-mount device (SMD) rework.
- Specialized Diagnostic Test Equipment: Digital Storage Oscilloscopes (DSO), spectrum analyzers, signal generators, logic analyzers, biomedical safety analyzers, and leakage current testers.
- RF Devices: High-frequency skin effect, impedance matching networks, RF filtering, electromagnetic interference (EMI) suppression, and shielding in clinical hospital equipment.
Key FPSC Exam Tips for Engineering Candidates
- Numerical Calculations: Practice standard circuit theorems without calculators (e.g. calculating Thevenin resistance $R_{th}$ or resonant frequency $f_0 = \frac{1}{2\pi\sqrt{LC}}$).
- Electro-Medical Safety: Pay close attention to electrical grounding, leakage current classifications (Type B, BF, CF applied parts), and hospital isolation transformers.
- Digital Logic: Be proficient with Karnaugh map minimization and flip-flop excitation tables.
