Product overview
5258A is a compact frequency scanner for base-station deployment, network optimisation and coverage investigation. Its standard RF range is 9 kHz–6.3 GHz. Configured functions include base-station scanning, spectrum clearance, coverage tests, base-station positioning and interference analysis. It supports 5G NR, LTE and other selected radio technologies, with remote control for public, private and rail communications field measurements.
Key features
- 5G NR / LTE coverage testing of up to 32 frequency points simultaneously; co-channel detection capability >25 dB.
- Blind scanning, Layer 2 / Layer 3 demodulation and MIB / SIB tests.
- 100 MHz real-time analysis bandwidth and TDD uplink/downlink-separated interference investigation.
- Spectrum, waterfall and channel-power displays; data saving and replay, reports and route statistics.
- Positioning with GPS, BeiDou and GLONASS, plus external-battery or vehicle-adapter power, according to configuration.
- Supports NB-IoT, CDMA2000, GSM, LTE, WCDMA, TD-SCDMA, EVDO and 5G NR technologies; test functions depend on the configuration.

Additional information
GPS positioning and dependent functions correspond to the 5258A-H01 configuration. Base-station scanning, real-time spectrum, interference analysis and other software functions are selected as required and are not all included with the base mainframe. A 20 GHz extension can be discussed separately, subject to the specified configuration quotation. The photo shows a scanner connected to a computer; the computer and example antenna are not indicated as standard mainframe items. Final price, lead time, licences and delivery scope depend on the quotation.
