  • Specification

✨ Standard Analog Modulation
Digital IF inside → stable reads → fewer spurs, fewer false peaks.
Auto tune/range/scale/couple → quick lock on targets → less knob work.

🧩 Tracking Generator (Up To 7.5 GHz)
Sweep filters, cables, and front-ends → map gain and match → align systems without guesswork.

🔍 Resolution & Detail
RBW down to 100 Hz or 10 Hz (model/option) → narrow for fine detail → wide for fast scans.
Peak table + markers → list tones → compare levels in seconds.

🤫 Sensitivity & Clarity
Low DANL with preamp → weak signals stand out → interference hunts get easier.
Low phase noise → cleaner skirts → precise close-in reads.

🖥 Display & Control
8″ (800×480) screen → traces look clear → menus feel simple → fewer missteps.
Intuitive UI → quick parameter tweaks → faster results you can trust.

📡 Where It Fits
Wi-Fi, Bluetooth, IoT, telecom → scan bands, spot spurs, verify links → lab and field both covered.

📜 Certified Accuracy
NABL calibration certificate → verified numbers → audit-ready reports.

📡 Wide Frequency Reach
9 kHz → 7.5 GHz → one box, many bands → lab and field both covered.

🤫 High Sensitivity (DANL)
−135 to −161 dBm (typ.) → very low noise floor → weak signals stand out.

🧼 Clean Close-In View (Phase Noise)
−80 to −98 dBc/Hz @ 10 kHz → tighter skirts → precise reads near carriers.

🎯 Amplitude Accuracy
<1.5 dB to <0.8 dB (nom.) → levels stay honest → comparisons hold up across bands.

🎚️ Fine Resolution (RBW)
Min RBW 100 Hz or 10 Hz (model/option) → narrow for detail → wide for speed.

🔗 Tracking Generator
Sweeps to 7.5 GHz → align systems → test filters, cables, and components quickly.

🧠 Digital IF Engine
Stable architecture → fewer spurs → repeatable measurements in tough RF scenes.

🖥️ Large, Clear Display
8″ TFT (800×480) → traces read easily → menus feel simple → fewer missteps.

🤖 Auto Helpers
Auto Tune / Range / Scale / Couple → quick lock on signals → less knob work, faster answers.

🖱️ User-Friendly Interface
Intuitive graphics + quick keys → set parameters fast → adjust without hunting.

📜 Certified Accuracy
NABL calibration certificate → verified numbers → audit-ready reports.

🛡️ Warranty
3-year coverage → long-term reliability → lower ownership risk.

🧰 Helpful Tools (Task → Outcome)

  • Spectrum compare → overlay traces → spot changes quickly.

  • 10 Hz RBW → ultra-fine detail on narrow signals.

  • AM demodulation → view/listen to depth → confirm modulation fast.
