<h1>Affordable RF Testing for Labs and Students: R&S FPC1500 + NGE103B in Action</h1>
<p><img src="https://your-image-url.com" alt="Rohde & Schwarz FPC1500 and NGE103B RF Demo Setup" style="max-width:100%; height:auto;" /></p>
<p>At a recent electronics show, Rohde & Schwarz presented a compact yet powerful RF testing setup — ideal for educational labs, beginner engineers, or anyone working with low-power RF modules.</p>
<h2>🔧 The Setup: Three Key Components</h2>
<ol>
<li>
<strong>R&S® FPC1500 Spectrum Analyzer</strong><br>
- Frequency range: 5 kHz to 3 GHz<br>
- Modes: Spectrum analysis, VNA, signal generator (optional)<br>
- Current use: Measuring output from an RF module around 433.150 MHz<br>
- Display: Stable CW-like peak with about 200 kHz bandwidth — possibly ISM band transmission
</li>
<li>
<strong>R&S® NGE103B Triple Output Power Supply</strong><br>
- CH1: 5.00V / 0.368A<br>
- CH2: 12.00V / 0.104A<br>
- CH3: Off<br>
- Use: Provides clean and adjustable power to the DUT<br>
- Ideal for classroom, lab, or embedded development environments
</li>
<li>
<strong>The DUT: Multi-Port RF Module</strong><br>
- Green PCB with multiple SMA ports<br>
- Likely a MIMO switch matrix, beamforming module, or RF splitter<br>
- Connected to spectrum analyzer via coaxial cables and USB to PC or controller
</li>
</ol>
<h2>🎯 What This Demo Shows</h2>
<ul>
<li><strong>Spectrum Analysis:</strong> Monitor RF output frequency and signal strength across channels</li>
<li><strong>Dynamic Power Monitoring:</strong> Real-time current readings help assess power consumption</li>
<li><strong>Harmonics or Filter Behavior:</strong> Nearby peaks may indicate harmonic content or filter leakage</li>
<li><strong>Controllable Switching:</strong> USB link suggests channel control or real-time path switching</li>
</ul>
<h2>📊 Live Spectrum Insight</h2>
<p>The screen shows a smooth frequency trace centered at <strong>433.150 MHz</strong> — a common ISM band. The relatively narrow shape and flat noise floor suggest good signal purity and dynamic range. Such clarity in a low-cost setup highlights how FPC1500 can support both beginners and pros.</p>
<h2>💡 Why This Setup Works</h2>
<p>This demo brings three key strengths:</p>
<ul>
<li><strong>All-in-one visibility:</strong> Power + Signal + Control</li>
<li><strong>Compact footprint:</strong> Desktop-friendly and easy to move</li>
<li><strong>Scalability:</strong> With a MIMO or beamforming module, it can scale into antenna and switching experiments</li>
</ul>
<h2>🏁 Takeaway</h2>
<p>Whether you're teaching RF concepts, verifying small module outputs, or testing in a student lab — this R&S combo delivers everything in one station. The FPC1500’s integrated features and the NGE103B’s clean rails form an excellent starter bench for RF development.</p>
