Anritsu Spectrum Analyzers
8 models with full specifications in Analyzers Spectrum.
This page summarizes Anritsu’s spectrum analyzer offerings in the Spectrum Master and BTS Master product lines and explains how the range is structured for field, installation and lab work. It is written for engineers and technical buyers who need to match measurement capability to application: required maximum frequency, noise floor and dynamic range, modulation or demodulation bandwidth, and site or bench portability. The copy highlights representative models and the attributes that distinguish them so you can quickly identify which model families to examine in the full specification table below.

How Anritsu structures its spectrum analyzer range
Anritsu’s products here fall into two practical groups: handheld Spectrum Master instruments (MS27xx and MS26xx model prefixes) and the BTS Master site/installation analyzer. Within the Spectrum Master family there are clear capability steps: compact handhelds for sub‑7.1 GHz work, midrange handhelds extending to 13–20 GHz, and high‑frequency variants designed for continuous coverage up to 43 GHz (MS2720T series). The MS2712E targets rugged field monitoring up to 4 GHz. The MT8221B is a multi‑function base‑station analyzer that combines spectrum analysis with cable/antenna testing and distance‑to‑fault.
Key technical differentiators to watch
Max frequency and the RBW/VBW specification determine whether an analyzer meets span and resolution needs — examples include models supporting RBW down to 1 Hz and up to 10 MHz (MS2724C). Noise floor and dynamic range are crucial for weak‑signal and interference work: MS2721B specifies a DANL < -163 dBm (1 Hz RBW at 1 GHz) and MS2723B lists a 101 dB dynamic range; MS2712E states >102 dB in 10 Hz RBW. Phase noise and amplitude accuracy matter when measuring close‑in signals and carriers; the MS2721A lists phase noise of -100 dBc/Hz at 10 kHz offset. If you need integrated demodulation bandwidth or wide IF outputs, note the MT8221B supports 20 MHz demodulation bandwidth and the MS2720T provides wide zero‑span IF bandwidth and internal frequency‑reference options.
Selecting the right model for the job
Match the analyzer to the measurement task rather than to brand alone. Use frequency coverage as the primary filter: choose MS2720T variants for continuous coverage to as high as 43 GHz; pick MS2724C or MS2723B where 20 GHz or 13 GHz coverage is required; choose MS2712E for rugged field use to 4 GHz; and MS2721B or MS2721A for handheld work up to 7.1 GHz with low DANL and built‑in preamplifiers. For site acceptance, commissioning and troubleshooting that require cable/antenna measurements and DTF, consider the MT8221B. Also compare RBW/VBW ranges, dynamic range/DANL, and available interfaces (Ethernet, USB) to ensure the instrument supports your workflows and data‑logging needs.
