RF Explorer Signal Generator Expansion Board - Australian Local Stock
Description
The RF Explorer Signal Generator Expansion Board is an internal upgrade module designed
to convert a standard RF Explorer RFE6GEN Signal
Generator into a full specification RF Explorer Signal Generator Combo. Once installed, this expansion board extends
continuous frequency coverage down to 100 kHz and up to 6 GHz with no gaps, while introducing active low pass harmonic filtering,
high-performance output amplification up to +18 dBm, and fine 0.25 dB amplitude step adjustments. Upgrading with this module
replaces the squarish, unfiltered output of the baseline RFE6GEN model with a clean sinusoidal output signal suitable for
demanding Scalar Network Analyser (SNA) measurements, filter testing, and RF circuit prototyping.
Key Features:
- Complete Combo Upgrade: Upgrades a standard RFE6GEN unit into a full specification RF Explorer Signal Generator Combo.
- Expanded Frequency Range: Extends frequency generation down to 100 kHz up to 6000 MHz (6 GHz) with continuous coverage.
- Active Harmonic Filtering: Internal filtering produces clean sinusoidal waveforms with significantly reduced harmonic distortion.
- Increased Output Power: Onboard amplifiers boost RF output power up to +18 dBm.
- Fine Amplitude Control: Precise power attenuation adjustments in 0.25 dB steps across the calibrated range.
- Full Tracking Generator Support: Synchronises with an RF Explorer Spectrum Analyser for 2-port Scalar Network Analysis (SNA).
- Free Open Source Software: Supported by RF Explorer for Windows software, with open-source Python and .NET API libraries for custom automation.

Package Contents:
- 1x RF Explorer Signal Generator expansion card
- 1x U.FL high-performance RF connection cable
Suggested Uses & Applications:
- Upgrading existing RFE6GEN baseline signal generators to full Combo capabilities without purchasing a complete new unit.
- Precise characterisation of RF filters, amplifiers, cables, and attenuators.
- General purpose bench testing and field testing requiring low-distortion sinusoidal signals across LF, VHF, UHF, and microwave bands.
Installation & Assembly Tips:
- ESD Precautions: Discharge static electricity and use anti-static precautions before handling the expansion board or opening the RFE6GEN enclosure.
- Cable Fitting: Exercise care when snapping the miniature U.FL RF cable onto the internal board connectors to avoid damaging delicate micro-coaxial pins.
- Firmware Upgrade: Update the RFE6GEN main firmware to the latest version immediately following hardware installation to enable full expansion board functionality.
- Software & Driver Downloads: Access manuals, firmware, and software directly from the RF Explorer download area.
Important Compatibility & Host Caveats:
- Host Specificity: Designed specifically for internal installation inside the RF Explorer RFE6GEN Signal Generator. It cannot be used as a standalone board or installed inside RF Explorer Spectrum Analyser models.
- Calibrated vs Extended Range: Power settings between -40 dBm and +10 dBm are factory calibrated. Power levels above +10 dBm (up to +18 dBm) or below -40 dBm (down to -60 dBm) operate in uncalibrated extended mode.
