Anritsu RF, Microwave, and Communication Analyzers

Anritsu's analyzers fall into clear functional groups useful for choosing equipment by task:

• Site Master (portable cable & antenna analyzers): examples include S332E, S332D and S820D. These are field-oriented instruments for installation, verification and troubleshooting of feeders and antennas. The S332E is positioned as an integrated handheld that combines cable/antenna measurements with a spectrum/interference analyzer. The S820D targets broadband microwave and radar feeder work, with standard operation to 25 MHz–20 GHz and an extended 2 MHz–20 GHz option and explicit waveguide support.

• Spectrum Master and bench spectrum analyzers: handheld and bench models cover a wide range of frequencies (examples below) and trade portability against top-end frequency and RF performance.

• Radio communication analyzers and test platforms: MT-series instruments (MT8820C, MT8820A, MT8801B) are configured for multi-system transmitter/receiver and protocol-level testing.

• Digital data/BERT: MP1632A is a dedicated digital data analyzer and bit-error-rate tester integrating generator and error detector functions.

Select on measurable technical attributes rather than marketing names.

• Frequency coverage: choose by the upper and lower frequency limits you need. For example, MS2667C extends to 30 GHz; MS2724B covers up to 20 GHz; bench legacy models like MS2602A and MS2601A provide different low-frequency or RBW extremes.

• Integrated functions: the S332E integrates cable/antenna analysis with a spectrum/interference analyzer in one handheld unit; S332D offers both cable/antenna and spectrum analysis with defined ranges for each.

• Measurement focus: if you need distance-to-fault (DTF) and typical cable/antenna metrics, the Site Master family is purpose-built (S332E supports DTF). For wide instantaneous bandwidths or very wide RBW use cases, consider MS2683A which specifies RBW to 20 MHz and a large typical dynamic range.

• Portability vs. lab performance: handheld units such as MS2724B and MS2711B trade size and battery operation against top-end noise and phase-noise figures offered in heavier bench instruments like MS2667C.

Match the instrument family to the task:

• Field installation and troubleshooting of base stations and feeders: Site Master models (S332E, S332D) provide return loss, VSWR, cable loss and, where noted, DTF. S820D extends the Site Master approach into microwave and waveguide-capable service ranges.

• Spectrum analysis and interference hunting in the field: handheld Spectrum Master models such as MS2724B (9 kHz–20 GHz) and MS2711B (100 kHz–3.0 GHz) offer battery operation and ruggedized RF inputs. For higher frequency or laboratory-grade phase noise and dynamic range, consider MS2667C (9 kHz–30 GHz) or MS2683A (9 kHz–7.8 GHz, wide RBW to 20 MHz).

• Radio-communication device verification and protocol-level testing: MT8820C/MT8820A are built for multi-system transmitter and receiver measurements and high-speed batch testing; MT8820C specifies RF outputs and level control suitable for automated test sequences.

• High-speed digital link validation and BER testing: MP1632A integrates a pulse pattern generator and error detector and covers 50 MHz to 3.2 GHz operation for serial digital testing and eye/BER measurements.

Before specifying, confirm the practical items that affect integration and field use:

• Connectivity and automation: some handhelds include Ethernet and USB (MS2724B lists RJ45 Ethernet and USB 2.0), while bench instruments commonly provide GPIB/LAN and richer control options (MT8820C includes GPIB, LAN and USB).

• Signal levels and damage thresholds: check maximum input/damage levels on spectrum front ends (for example many Anritsu spectrum products list a safe input around +30 dBm). If you need very low noise-floor measurements, compare displayed average noise level (DANL) and preamplifier options (MS2711B cites DANL < -115 dBm; MS2602A cites -135 dBm).

• Special-purpose functions: waveguide dispersion correction and media lists are offered on models targeted at microwave and radar feeder work (S820D lists waveguide dispersion correction and compatible flange lists). For multiport or RF source needs, check the RF output configuration and resolution on radio communication platforms (MT8820C provides main and auxiliary outputs with 0.1 dB resolution).
