The Keysight 70300A RF Tracking Generator is a 2-slot modular instrument that transforms 70000 series spectrum analyzers into stimulus-response measurement systems. Operating as a slave module controlled by an HP 70900A/B local oscillator, the 70300A delivers swept RF stimulus whose frequency tracks the analyzer’s tuned frequency in real time. This closed-loop architecture enables precise characterization of gain, frequency response, isolation, and return loss across component and subsystem designs.
Technical Specifications
Frequency Range: 20 Hz to 2.9 GHz
Dynamic Range: Greater than 124 dB (with 70300A and 71100C)
Resolution Bandwidths: As narrow as 10 Hz for high selectivity measurements
Output Power Characteristics:
• Maximum leveled power: -10 dBm
• Amplitude control range: 0 to -91 dBm
• Vernier range: 11 dB with 0.01 dB resolution
• Power sweep range: 0 to -10 dB
• Output attenuator: 70 dB in 10 dB steps
• RF off residuals: 124 dB) permits accurate measurement of filter rejection and switch isolation without signal averaging. Sub-10 Hz resolution bandwidth enables isolation of specific signal paths in presence of adjacent interference. Fine amplitude control with 0.01 dB vernier resolution supports both swept power analysis and fixed-level stimulus applications.
– Typical Applications
• Scalar network analysis for two-port device characterization
• Filter magnitude response and stopband rejection measurement
• Isolation and return loss evaluation in RF components
• Gain flatness and frequency response analysis
• Switch insertion loss and port-to-port isolation testing
– Compatibility & Integration
The 70300A integrates into the HP/Agilent 70000 Series modular measurement system via the Agilent 70871A scalar personality module. Control is managed through the scalar software personality. The instrument is compatible with Keysight 70000 series spectrum analyzers and lightwave signal analyzers.
