  • Special Features
  • Specification

🔧 Core Performance (Cause → Effect)

  • Digital IF inside → stable reads → fewer spurs, fewer false peaks.

  • DANL down to −161 dBm (with preamp) → weak signals appear → low SNR hunts get easier.

  • Phase and level hold steady → repeat runs match → decisions feel safe.

📡 Tracking & Tests (Task → Outcome)

  • Tracking Generator to 7.5 GHz → sweep filters, cables, and front-ends → map gain and match quickly.

  • System calibration → align paths end-to-end → cut guesswork.

  • Component checks → verify passbands and notches → spot drift early.

🖥 See It Clearly (Action → Result)

  • 8″ display → traces read at a glance → markers land accurately.

  • Clean menus + quick keys → fewer steps → faster answers.

🤖 Auto Helpers (Speed → Confidence)

  • Auto Tune / Auto Range / Auto Scale / Auto Couple → fast lock on targets → less knob work, fewer mistakes.

📜 Verified Accuracy (Trust → Compliance)

  • NABL calibration certificate → numbers you can cite → audit-ready reports.

🧳 Portable Build (Field → Lab)

  • Compact, lightweight frame → easy carry on site → easy fit on tight benches.

✨ 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 → more 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)
10 Hz → 1 MHz → narrow for detail → wide for speed.

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

🖥️ Clear Display
8″ TFT, 800×480 → traces read easily → menus feel simple.

🤖 Auto Functions
Auto Tune / Range / Scale / Couple → quick lock → fewer knob turns.

🔌 Connectivity
USB / LAN / GPIB → move data easily → script and control remotely.

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

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