Request a quoteProduct overview
5252D integrates signal generation and analysis in a modular multichannel test platform. The RF range is 400 MHz–6 GHz with 200 MHz FR1 RF bandwidth. It supports 5G NR and multiple mobile radio technologies for signal generation, analysis and base-station testing in wireless R&D, production, communications laboratories and maintenance. Hardware modules, protocol functions and extension bands are configured for the project.
Key features
- Independent baseband channels with integrated transmit/receive, modular expansion and parallel testing.
- Real-time generation of 5G NR, TDD-LTE, FDD-LTE, LoRa, TD-SCDMA, WCDMA and GSM signals with flexible parameter settings.
- Multi-domain analysis and tests for EVM, maximum power, OBW, ACLR, total-power dynamic range, transmitter off power, transient response, port time alignment and spurious emissions.
- Interference and AWGN signals support receiver reference sensitivity, dynamic range, adjacent-channel selectivity, intermodulation and in-channel selectivity tests.
- One-click IQ capture and storage, with export through front USB or rear LAN; touchscreen and block-diagram interface simplify configuration.
- Supports RF performance testing for base-station R&D, automated production tests, communications laboratories and maintenance.

Additional information
Extension bands, multichannel cascading and protocol functions require the appropriate hardware and option combination; they are not all included by default. The 100 / 400 MHz entry for 5G NR signal analysis describes the signal-analysis configuration scope and does not mean every base RF channel has 400 MHz analogue bandwidth; see the core RF specifications. The image illustrates a modular configuration. Actual module quantity, functions, accessories, price and lead time follow the quotation.
