The Rigol DSA815 is a high-performance spectrum analyzer with a frequency range of 9 kHz to 1.5 GHz. It includes a preamplifier, AM/FM demodulation, and standard functions for portable RF applications. This compact and lightweight analyzer comes with an optional EMI filter and Quasi-Peak detector kit, as well as a tracking generator for comprehensive testing. With advanced digital IF technology, the DSA815 offers excellent reliability and sensitivity for demanding RF applications..
✨ Why It Helps (Cause → Effect)
Digital IF inside → stable measurements → fewer false peaks.
High sensitivity + preamp → weak signals pop up → small issues get found early.
Big display + clear UI → settings feel obvious → mistakes drop.
🧩 Key Capabilities (Tight, Plain)
AM/FM demod built in → hear and view modulation → verify quickly.
Auto tune/range/scale/couple → analyzer finds good settings → you save steps.
Peak table → lists top signals → compare levels at a glance.
Tracking generator (option/variant) → sweep filters and cables → map frequency response fast.
EMI filter + quasi-peak (option) → check noise like a compliance test → fewer surprises later.
🧪 What You Can Do (Task → Outcome)
Communications: scan bands → spot carriers and spurs.
Signal testing: measure harmonics → judge distortion fast.
RF development: tune antennas and amps → improve match and gain.
EMI pre-checks: apply CISPR-style filters → fix problems before the lab.
🛠️ Ease Of Use (Action → Result)
Tap auto → lock the signal → read clean numbers.
Enable preamp → lift weak traces → measure with confidence.
Add demod → confirm AM/FM depth → align parameters fast.
📡 Frequency Range
9 kHz → 1.5 GHz → covers audio to RF → fits many test cases.
🔎 DANL (Noise Floor)
−135 to −161 dBm (typ.) → very quiet baseline → see weak signals clearly.
🧼 Phase Noise
−80 to −98 dBc/Hz @ 10 kHz offset → low jitter → precise spectrum views.
📏 Resolution Bandwidth (RBW)
10 Hz → 1 MHz → narrow for detail → wide for speed.
📢 Preamplifier
Built in → weak signals get boosted → accuracy improves.
🎛️ AM/FM Demodulation
Standard feature → listen, view, and check modulation directly.
🔗 Tracking Generator
Included → sweep frequency response → measure impedance quickly.
⚡ Optional EMI Tools
EMI filter + quasi-peak detector kit → advanced compliance tests → catch noise issues.
📐 Optional VSWR Kit
Add-on → test standing waves → verify antenna match.
🤖 Auto Functions
Auto Tune, Auto Range, Auto Scale, Auto Couple → fast setup → less manual tweaking.
🖥️ Interface & Display
8-inch TFT (800×480) → clear view → simple navigation.
📜 Calibration
NABL-certified → verified accuracy → trusted data.
🔌 Connectivity
USB, LAN, GPIB → easy data transfer → smooth remote control.
⚡ Max Input Voltage
50 V → safe handling for many signals.
🛡️ Warranty
3 years → long-term support → peace of mind.
