Typical spectrum analyzer accessory applications

Accessories allow compatible analyzers to support more complete laboratory, production, EMI and field-service workflows.

EMI pre-compliance

Combine EMI software, suitable antennas, cables and external accessories to investigate radiated or conducted emissions.

Interference hunting

Use directional antennas and a portable analyzer to identify signal direction and narrow down the interference source.

Return-loss testing

Add a compatible reflection bridge and software package to evaluate antennas, cables and RF components.

Modulation analysis

Add supported analog or digital modulation software to examine compatible communications signals.

Noise-figure testing

Use a noise-source driver, suitable noise source and compatible analyzer software to configure a noise-figure measurement system.

Portable RF surveys

Batteries, carry bags, GPS accessories and field antennas support mobile spectrum monitoring and site investigations.

How to select the correct spectrum analyzer accessory

Begin with the measurement objective, then confirm analyzer, frequency and connector compatibility.

Identify the analyzer model

Software licences and hardware accessories may be limited to a specific SSA, SVA, SHA or SNA series.

Confirm frequency coverage

The antenna, cable, adapter, bridge and attenuator should cover the complete measurement frequency range.

Check all connectors

Confirm connector family, gender and mechanical compatibility at every connection in the measurement path.

Account for cable loss

RF cable and adapter losses increase with frequency and may affect the signal level reaching the analyzer.

Separate hardware and software

Some measurement systems require both a hardware accessory and a separate software activation.

Protect the analyzer input

Confirm maximum input power and use suitable attenuation or protection before connecting an unknown RF source.

Need help configuring your Siglent spectrum analyzer?

Send RCC Electronics the analyzer model, serial number or installed options, required measurement, frequency range, expected signal level, connector type, cable length, field or laboratory use and whether EMI, reflection, modulation, noise-figure or VNA measurements are required.

Frequently asked questions

Common questions when selecting spectrum analyzer accessories.

Can every software option be installed on every Siglent analyzer?

No. Software options are normally tied to specific analyzer families and sometimes to particular models or firmware versions. Confirm the complete instrument model before ordering.

Is EMI software alone enough for an EMI test?

No. A practical EMI setup may also require antennas or LISNs, cables, attenuators, preamplifiers, near-field probes and the applicable measurement procedure.

What frequency rating should an RF cable have?

The cable should be rated above the highest test frequency. Cable loss, connector quality and power handling should also be suitable for the measurement.

What is a reflection bridge used for?

A reflection bridge separates incident and reflected RF energy, allowing a compatible analyzer and software to evaluate reflection-related characteristics such as return loss.

Why are hardware and software sometimes sold separately?

The physical accessory performs the RF connection or signal conditioning, while the software enables the analyzer's measurement and calculation functions.

What information should be provided before ordering?

Provide the analyzer model, required measurement, frequency range, signal level, connector types, existing software options and whether the accessory will be used in the laboratory or field.
