Rigol DSA875

Rs. 807120.00

The Rigol DSA875 is a high-performance spectrum analyzer with a frequency range from 9 kHz to 7.5 GHz. It includes a Tracking Generator and offers outstanding signal detection, achieving DANL as low as -161 dBm with a pre-amplifier. The analyzer features a large 8-inch display with 800×480 resolution, and advanced functions such as Auto Tune, Auto Range, and Auto Scale, making it ideal for both portable and benchtop RF applications. Now with an NABL Calibration Certificate and 3 years warranty..

  • Detail
  • 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.
