# Rigol SPA-815TGE 1.5 GHz Spectrum Analyzer with Tracking Generator and EMI Filter # Rigol SPA-815TGE 1.5 GHz Spectrum Analyzer with Tracking Generator and EMI Filter ## Key Features At A Glance - Frequency coverage from 9 kHz to 7.5 GHz across the SPA-800 series (SPA-815: 1.5 GHz; SPA-832: 3.2 GHz; SPA-875: 7.5 GHz) - All-digital IF technology with 10 Hz minimum resolution bandwidth for distinguishing closely spaced signals - Displayed Average Noise Level to -161 dBm (typ.) with preamplifier on, normalized to 1 Hz - Phase noise <-98 dBc/Hz @ 10 kHz offset (SPA-832/875); <-80 dBc/Hz (SPA-815) - Level measurement uncertainty <0.8 dB (SPA-832/875); <1.5 dB (SPA-815) - Tracking generator included on all models (100 kHz to instrument's frequency range) - LAN (LXI core 2011), USB Host & Device, and optional GPIB connectivity for automated test integration - 8-inch WVGA (800x480) TFT LCD display with EMI filter and quasi-peak detector kit included The Rigol SPA-800 Series is a family of digital IF spectrum analyzers spanning 9 kHz to 7.5 GHz, available in three frequency tiers: the SPA-815 (to 1.5 GHz), SPA-832 (to 3.2 GHz), and SPA-875 (to 7.5 GHz). All three models share the same all-digital IF architecture, 8-inch WVGA display, and a compact benchtop form factor measuring 361.6 mm x 178.8 mm x 128 mm. A spectrum analyzer shows signal energy distributed across a range of frequencies — the frequency-domain view of what signals are present, at what frequency, and at what power level. The SPA-800 Series is designed for RF design and characterization, EMC pre-compliance testing (EMI filter and quasi-peak detector kit included), and educational applications. The included tracking generator extends utility into scalar component characterization — filter passband measurement, amplifier gain flatness, and cable insertion loss. ## Brand Heritage Rigol Technologies is a Chinese test and measurement manufacturer that has expanded its presence in the global professional T&M market over the past two decades. Rigol maintains its own brand and product development; the SPA-800 Series is distributed through authorized partners including Com-Power Corporation. ## Compare Other Models in This Series The SPA-800 Series consists of three models that share an identical all-digital IF architecture, display, and feature set — differing primarily in maximum frequency coverage and certain RF performance specifications. The SPA-815 covers 9 kHz to 1.5 GHz, the SPA-832 extends to 3.2 GHz, and the SPA-875 reaches 7.5 GHz. All three include a tracking generator covering the instrument's frequency range, EMI filter and quasi-peak detector kit for pre-compliance work, and 8-inch WVGA display. Beyond frequency range, the SPA-832 and SPA-875 share improved RF specifications relative to the SPA-815 — including lower phase noise (<-98 dBc/Hz vs. <-80 dBc/Hz at 10 kHz offset), tighter level measurement uncertainty (<0.8 dB vs. <1.5 dB nominal), and a 10 Hz minimum resolution bandwidth (versus 100 Hz on the SPA-815). Preamplifier coverage is standard on the SPA-815 (20 dB nominal) and available as an option on the SPA-832 (PA-DSA832) and SPA-875 (PA-DSA875) at 17 dB nominal. Each new SPA-800 model linked below is its own dedicated product page with condition-matched pricing, current inventory status, and accessory configuration details. Confirm the specific model that matches your frequency coverage requirement and any required options before issuing a purchase order. The SPA-875 is the top-tier model in the SPA-800 family, covering 9 kHz to 7.5 GHz. It shares the improved RF specifications of the SPA-832 (10 Hz minimum RBW, <-98 dBc/Hz phase noise at 10 kHz offset, <0.8 dB level measurement uncertainty) while extending coverage through the 3.2 GHz to 7.5 GHz range — relevant for applications addressing the upper WiFi bands, ISM bands, and lower microwave work. The model decision is primarily driven by maximum frequency requirement. For applications below 1.5 GHz where premium phase noise is not required, the SPA-815 offers integrated 20 dB preamplifier as standard. For applications requiring 10 Hz minimum RBW, improved phase noise, and tighter level uncertainty — but only sub-3.2 GHz coverage — the SPA-832 is appropriate. For applications requiring coverage above 3.2 GHz (WiFi 5 GHz band, ISM bands above 3 GHz, lower microwave), the SPA-875 is required. The optional preamplifier (PA-DSA832 or PA-DSA875) improves DANL by approximately 20–25 dB relative to PA-off operation and is a meaningful investment for applications measuring low-level signals near the instrument's noise floor.
