This unit
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.
Agilent / Keysight 70300A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 70300A. Calibration covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 70300A faults: YIG oscillator failure (no output or loss of lock), step attenuator wear (output drops or steps at set attenuation), ALC loop failure (uncontrolled output power), I/Q modulator assembly failure. HP/Agilent 836xx series most common faults are YIG oscillator failure and step attenuator contact wear causing output steps or drops at specific attenuation settings. Keysight E4428C/E4438C units most commonly develop ALC loop failure and I/Q modulator assembly faults. YIG oscillator replacement and attenuator service are stocked repairs.
