Overview
The Desite TS-PS6000P is a compact, precision-engineered broadband RF phase shifter designed for laboratory, R&D, and automated test environments requiring accurate, repeatable phase manipulation across the 3.5–6.0 GHz band. Operating on the principle of distributed transmission-line phase delay with digitally controlled switched-path topology, the TS-PS6000P delivers discrete phase shifts in 5.625° increments over a full 0–355° range—enabling deterministic control of signal timing without altering amplitude or introducing significant group delay variation. Its bidirectional RF architecture supports both forward and reverse signal flow, making it suitable for reciprocal calibration setups, loopback configurations, and dual-path interference experiments. The device is optimized for applications demanding low insertion loss (<6 dB), high port match (>12 dB return loss), and robust thermal stability under continuous operation at up to +25 dBm input power.
Key Features
- Ultra-compact form factor (102 × 64 × 25 mm) with rugged powder-coated aluminum housing for EMI shielding and mechanical durability
- Integrated monochrome OLED display for real-time phase setting, status indication, and firmware version visibility
- On-device tactile push-button interface for manual phase adjustment and mode selection—no host PC required for basic operation
- Audio feedback via integrated piezo beeper confirms each phase step change, enhancing usability in noisy lab or field environments
- Micro-USB powered (5 V DC, <500 mA) and controlled—eliminates need for external power supplies or batteries
- Gold-plated SMA connectors ensure low-contact resistance, high repeatability (>500 mating cycles), and stable VSWR performance
- Firmware-upgradable architecture supporting future enhancements to control protocol, resolution modes, or calibration data storage
Sample Compatibility & Compliance
The TS-PS6000P is compatible with standard 50 Ω RF systems used in wireless communication testing, including LTE-A, Wi-Fi 6/6E, and 5G NR FR1 bands. It meets IEC 61000-4-2 (ESD immunity) and IEC 61000-4-3 (radiated RF immunity) requirements for laboratory-grade instrumentation. While not certified for safety-critical or airborne deployment, its design adheres to IPC-A-610 Class 2 workmanship standards for electronic assemblies. The device operates within FCC Part 15 Subpart B and CE RED Directive 2014/53/EU emission limits when integrated into compliant test systems. For GLP/GMP-aligned validation workflows, traceable calibration certificates (NIST-traceable phase accuracy ±1.5° at 4.5 GHz) are available upon request.
Software & Data Management
Desite provides a free, Windows-based PC application (v3.2+) supporting USB HID-class enumeration—requiring no driver installation. The GUI enables remote phase programming, sweep sequencing (linear/logarithmic), and timestamped logging of phase settings and system status (temperature, supply voltage, error flags). Command sets follow SCPI-like syntax over virtual COM port (e.g., :PHAS:SET 180.0, :STAT:QUES?) for seamless integration with Python, LabVIEW, MATLAB, or TestStand automation frameworks. Optional Ethernet control (via IEEE 802.3 10/100BASE-TX) adds TCP/IP socket and UDP broadcast support, enabling multi-unit synchronization and centralized fleet management. All configuration changes are stored in non-volatile memory and persist across power cycles. Audit trail functionality—including user ID tagging and change timestamps—is available in enterprise license tiers compliant with FDA 21 CFR Part 11 Annex 11 requirements.
Applications
- Antenna array calibration and beamforming verification in anechoic chambers
- MIMO channel emulation and spatial correlation analysis
- RF cancellation loop tuning for active interference suppression systems
- Phase-sensitive receiver testing (e.g., IQ imbalance characterization)
- Education and prototyping platforms for phased-array radar fundamentals
- EMC pre-compliance testing involving phase-controlled coupling path simulation
- Calibration reference for vector network analyzers (VNA) using known-phase offset methods
FAQ
Is the TS-PS6000P compatible with Linux or macOS?
Yes—USB HID mode is OS-agnostic; command-line control via serial terminal or Python’s pySerial is fully supported. Precompiled binaries for Linux ARM/x86 are available in the Desite Developer Portal.
Does the device require external calibration before use?
No—factory-calibrated phase states are stored in internal flash memory. NIST-traceable calibration reports are optional and provided separately for metrology-grade deployments.
Can multiple TS-PS6000P units be synchronized over Ethernet?
Yes—using multicast UDP commands with microsecond-level timestamp alignment, enabling coordinated phase sweeps across up to 16 units in a single subnet.
What is the maximum operating temperature range?
The specified ambient operating range is –10 °C to +55 °C. Derating applies above +45 °C: max input power reduced to +20 dBm to maintain phase accuracy within ±2.0°.
Is firmware update capability accessible to end users?
Yes—updates are delivered as signed .dfu files via the PC application, with rollback protection and CRC-verified flashing to prevent corruption.
