DESCRIPTION:

The Bird Technologies 7001A900-3 BDS2 Receiver (Ethernet + Serial) is an advanced RF diagnostic receiver module within the Bird Diagnostic System 2 (BDS2) framework. It processes high-fidelity voltage (V), current (I), and phase () signals from a connected V-I sensor to compute essential RF parameters such as impedance, delivered power, reflection coefficient, and phase relationships across multiple frequency components (fundamental, harmonic, and intermodulation). 

This variant adds a serial communications interface alongside standard Ethernet, enabling flexible integration into test and automation environments that require legacy connectivity or direct instrument control via RS-232/serial protocols. The 7001A900-3 is ideal for diagnostic measurement in non-50 RF systems — such as plasma process tools, RF delivery networks, and impedance matching environments — where deeper signal insight is necessary beyond what conventional 50 power meters can provide. 

Key Features 

• Receiver Module: Model 7001A900-3 — includes Ethernet and Serial communication interfaces for flexible system integration. 

• Full V-I- Processing: Simultaneous measurement of voltage, current, and phase from an inline sensor head, enabling true complex impedance and power computation. 

• Multi-Frequency Tracking: Supports tracking up to 3 fundamental frequencies, with multiple harmonics and intermodulation products, for comprehensive RF analysis. 

• Network & Serial Control: Ethernet for modern remote control and data logging; Serial (RS-232) for legacy system support and direct instrument interfacing. 

• Advanced Measurement Modes: Supports Spectral Search and, with optional licenses, Time Domain analysis for detailed waveform characterisation. 

• Precision RF Metrics: Calculates impedance magnitude/phase, return loss, and reflection coefficient across the RF spectrum monitored by the connected sensor. 

• System Flexibility: Designed to work with a variety of BDS2 V-I sensor heads and phase-stable cable assemblies (ordered separately). 

Typical Use Suitability:
Best suited for advanced RF diagnostics and system monitoring in non-50 environments where comprehensive metrics beyond forward/reflected power — such as impedance and phase relationships — are critical for process control, chamber matching, and RF system optimisation. 

Technical & Performance Details 

• Frequency Tracking: Up to 12 simultaneous frequency components (fundamentals + harmonics + intermodulation). 

• Frequency Range: Sensor-dependent, generally covering ~307 kHz to ~252 MHz. 

• Resolution & Accuracy: Frequency resolution ~100 Hz; typical measurement modes include voltage, current, phase, frequency, impedance, and power at user-selected frequencies. 

• Update Rate: ~100 Hz typical measurement update rate. 

• Operating Modes: Tracking mode, Spectral Search mode; optional Time Domain mode available with separate license. 

• Power & Environmental: Receiver typically operates from 15 VDC @ ~2.5 A; environmental operating/specification ranges align with RF system diagnostic hardware standards.
