IN Brief:
- A new handheld combi analyser combines spectrum, real-time spectrum, network and power measurements.
- The R&S HMP5050 adds up to five independent DC bench-supply channels.
- Both will be shown at electronica 2026; the manufacturer has not disclosed full analyser specifications.
Rohde & Schwarz plans to introduce a new handheld combination analyser and present the R&S HMP5050 five-channel DC power supply at electronica 2026 in Munich. The unnamed portable instrument combines spectrum analysis, real-time spectrum analysis, vector network analysis and RF power-meter measurements, according to the manufacturer’s exhibition briefing. The HMP5050 provides up to five independent outputs for laboratory power work.
These are specific product introductions within a much broader show programme that also covers existing oscilloscopes, EMC receivers, satellite testing and quantum instrumentation. Full model specifications for the handheld analyser and commercial availability have not yet been announced.
Portable RF instruments can be useful where testing has to move between a laboratory, manufacturing area and installed equipment. Typical applications include investigating unexpected emissions, checking signal levels and assessing connections in a constrained environment. Engineers selecting an analyser should examine frequency coverage, noise floor, amplitude accuracy and dynamic range against the signals they actually need to measure. A device that is convenient to transport does not necessarily replace specialist equipment when very low noise or wide instantaneous bandwidth is required.
Battery operation, screen visibility and ruggedness may also matter in the field. The ability to store a measurement trace is useful, but repeatable troubleshooting depends on recording the instrument settings, probe configuration and conditions under which the trace was acquired. Where measurements are used for formal compliance work, traceability and calibration become as important as portability. A field check that indicates a problem is not automatically a substitute for a test made in a controlled accredited environment.
A multichannel bench supply serves a different set of design needs. Prototypes often require several independent voltage rails for analogue front ends, processors, motor-control circuits and interface hardware. More than one channel can reduce clutter and allow coordinated switching, but engineers should check the permitted power-sharing modes, current limits, output noise and channel isolation. A nominal five-channel count says little about how the unit behaves when several channels approach their rated capacity simultaneously.
Power-up sequencing is particularly important when a design includes sensitive semiconductors. Bringing up one rail before another can put unintended voltages onto pins through protection structures, sometimes damaging the device or making a prototype behave unpredictably. Test supplies with programmable sequencing can simplify investigation, provided their transient response and interlocks are suitable for the circuit. Logging voltage and current through startup can also reveal brief events that are invisible on a static front-panel reading.
Electronica brings component vendors and instrument manufacturers together, making it possible to compare measurement requirements with emerging circuit designs. For RF, embedded and power engineers, the central purchasing question is whether additional functionality improves test coverage or only duplicates capability already available in the lab. Software integration, instrument control commands, calibration intervals and support commitments can determine lifecycle value more reliably than an exhibition demonstration under ideal conditions.
Measurement automation is a further purchasing criterion across both categories. Engineers increasingly want repeatable test scripts and consistent capture of readings when comparing hardware revisions. Remote control interfaces, export formats and synchronisation with other instruments may decide whether a device can be integrated into a validation bench.
Firmware updates can change instrument functions, so teams need to document software versions when measurements form part of a formal qualification record. These lifecycle details will be more meaningful than general promotional claims about a versatile bench or field instrument. A meaningful comparison requires bench measurements with identical setups and recorded uncertainty, particularly where different instruments are evaluated across analogue, RF and power tests.
At electronica, Rohde & Schwarz plans to demonstrate both the new handheld combi analyser and the HMP5050 at its stand in hall A4. Engineers can compare their functions against existing laboratory equipment and discuss real use cases, including field troubleshooting and multi-rail prototype development. The combination analyser’s frequency limits, sensitivity and order availability remain to be specified; no figures should be inferred from other instruments in the manufacturer’s catalogue.
For the HMP5050, the practical questions concern current limits, output isolation, sequencing and remote control. The two additions address different measurement workflows without implying that every instrument elsewhere on the stand is newly released.
