Automating RF Measurements
In the last few years, there has been explosive growth in the demand for PCB/PCBAs with RF signal performance. The growth in various applications has led to an ever-growing need for fully automated RF measurements requiring probe placement, RF measurement, and data collection.
- Advanced Communication System – there is extensive use of RF PCBs in communication systems, especially in booster stations and receivers. They are also integral to the automotive industry.
- Military - The production of ammunition and firearms relies heavily on high-frequency PCBA materials.
- Radar Systems - These PCBs are pivotal, especially in the maritime and aviation sectors. Radar systems play a crucial role in avoiding obstacles such as icebergs in marine applications and guiding aircraft to prevent accidents.
- Medical Systems - RF PCBAs have extensive use in manufacturing medical electronics, including monitoring and diagnostic devices.
- Consumer Products – Cell phones, wrist watches, cash registers, personal computers, printers, telephones, garage door receivers, wireless temperature probe receiver, and RF universal remote controllers.
The integration of RF measurement capability in an automated Flying Probe Test, allows engineers to engage multiple probes on a PCB simultaneously, streamlining the measurement process and significantly enhancing productivity.
Seamless Multi-Probe Engagement
Traditionally, performing RF measurements required meticulous manual effort, adjusting individual probes and recalibrating for each test scenario. The new integrated RF probe module automates this process, enabling simultaneous engagement with multiple probes. This automation frees engineers to focus on analysis rather than setup, ultimately reducing errors and improving test repeatability.
Comprehensive Measurement Capability
The RF probe module offers a broad spectrum of measurement capabilities, supporting single-ended, differential mode, mixed mode, and common mode measurements, ensuring comprehensive data acquisition for various signal types. To further enhance measurement accuracy and ease of use, the integrated RF probe module incorporates several advanced features:
- S-Parameters in Frequency and Time Domains: Engineers can analyze S-parameters in the frequency domain and TDR in time domain for in-depth signal integrity diagnostics.
- Insertion and Return Loss Recording: The module records key parameters such as insertion loss and return loss across all tested lanes, ensuring a complete understanding of signal performance.
- Integrated Borescope for Probe Landing Monitoring: One of the standout features of this system is the inclusion of a borescope camera to monitor probe landings. Given the fine pitch of modern RF probes, ensuring precise probe contact is crucial, particularly for first article tests. The borescope provides real-time visual feedback, allowing engineers to verify probe placement and maintain optimal electrical coverage.
A Transformation in RF Testing
As technology advances, so must our tools. The integration of intelligent RF measurement capabilities into the FLS Flying Probe Test System marks a significant step forward. With this integrated RF measurement capability, engineers can conduct high-precision measurements with unprecedented efficiency.
