Work Experience

May 2026 – Present

LabVIEW // Python // PyVISA // GPIB // SCPI // LTspice // RF Test Automation

RF Debug: Investigated unwanted PLL spurs by decoding SPI register writes against datasheet bit fields, calculating divider settings, PFD frequency, spur spacing, and integer-boundary risk.
Bias-Tee Verification: Performed circuit-level review of 50 Ω/75 Ω bias-tee networks, calculating impedance, insertion loss, return loss, and SPICE-based risk estimates to define VNA validation points.
PCB Rework Validation: Created test recommendations for bias-tee PCB rework variants, identifying shunt-loss paths, impedance-matching risks, GHz parasitic limitations, and required VNA measurements.
ATE Modernization: Reverse-engineered legacy LabVIEW workflows and prototyped a Python/PyVISA architecture separating instrument control, RF test sequencing, calibration loading, and report generation.
Instrument Control: Integrated LabVIEW drivers over GPIB/SCPI (IEEE 488.1/488.2) for Rohde & Schwarz and Keysight RF test equipment.

June 2025 – August 2025

PNA-X VNA // Signal Analyzers // Oscilloscopes // Multimeters // SMT/THT Rework

RF Characterization: Characterized block-up converters using PNA-X VNAs, signal analyzers, oscilloscopes, and multimeters to validate gain, output power, saturation, and spurious parameters against product specifications.
Rework & Assembly: Performed microscope-assisted SMT/THT soldering, rework, inspection, and assembly on BUC/LNB hardware.
