Pre-Compliance testing needn’t cost the earth with Rigol’s spectrum analysers for less than £1000

Emerging testing options are easing the demands on designers surfing the RF and EMC waves. Faced with a daunting landscape and broader, tougher ranges of testing configurations and standards, wiser companies are accessing newly emerging pathways through today’s new testing criteria. With the budget in mind, we explore these new sourcing options. As UK users seek a more acceptable testing cost base, careful selection of spectrum analyser instrument combined judicious use of rental packages can help you tune your in-house test facility to cover line harmonic/disturbance immunity. You can gain economics from in-house testing and help your designers manage risk and reduce the uncertain costs.

Designer engineers and production managers have a common interest in tools to help meet the taxing range of standards and test criteria expected in producing today’s complex designs, and to achieve this goal with a toolkit flexible enough to cover the field for the business without destroying profits. “The trends in spectrum test, power test and analysis have led to huge boost in flexibility of tests we can offer” explains Doug Lovell “for example, we have lower-cost automated and programmable spectrum analysers adopted into the design phase, pre-production trials and into automated manufacturing test – in other words a very much wider range of applications and features is expected from the same toolkit”. Telonic Ltd. offer three advantages for EMC: pure performance sufficient to help sniff out problematic emissions (especially low Noise Floor performance), good overall reliability and uncompromised ease of use covering all common kinds of analysis– especially allowing flexible logging of test results. Top end analysers are a daunting alternative – a fully compliant EMC test instrument in accordance with CISPR 16-1-1 can be massively costly.

Enter the latest generation of suppliers changing the economics of in-house testing.


The latest bonus for economic lab development is with the 2GHz and 3GHz-capable models:DSA1030A and DSA1030 models are available with optional 3 GHz -TG (tracking generator). The A-series’ own built-in pre-amplifier allows up to -148 dBm Displayed Av. Noise Level (DANL), and with advanced standard functions like power measurement, Harmonic Distortion or TOI (3rd order intermodulation) the  DSA1030A analysers are ideal for powerful and versatile 9kHz-3GHz measurements. If you need only 1.5GHz, Rigol’s DSA815 and DSA815-TG’s are a very economic price.

An example of one such second generation spectrum instrument is RIGOL’s DSA-range.  Notably, when a RIGOL model DSA815 was subject to the extra hurdle of fitness for EMI Lab via CISPR’ s requirements recently, this budget instrument was found to achieve much of this extreme EMI-Lab oriented standard. Essential pre-compliance for CE and other international standards certifications is now possible at a fraction of the cost.

DSA in the RIGOL-UK offerings now add EMI filters, Quasi Peak Detectors to help in-house EMC testing, plus the advanced measurement kit (AMK) as standard on selected models. Telonic is now packing free enhancement specially aiming to help savings on in-house EMC Pre Compliance testing – suited to both conducted emissions and radiated emissions – right up to 3 GHz.


For EMC, Telonic also offers an optional ready-to-connect Near Field Probe Set  fitting all Rigol DSAs, Line Impedance Stabilisation Network (LISN) and the new TeKBox Tem Cell for conducting radiated emission tests.

The second big hurdle is how to access an ever expanding range of tests for wider EN standards. A good rental partnership with an engineering-led supplier can be crucial to help with a wide range of preliminary tests before the tests for the standards, immunity allowance tests, and stress tests:

“These tests require advanced high-reliability instruments of high value – our customers want to get access to the right equipment and support without breaking budget and timescales – sometimes just preliminary checks are sufficient and there is no need to purchase” adds Telonic’s Doug Lovell, where the team aims to deliver more innovate equipment sourcing and helps customers perform pre-emptive testing strategies.  The figure below is a quick guide to help navigate just power immunity/stress test areas:


RIGOL DM3068 Bench Multi Meter With Digital Data Logging And Chart Display

Keeping a close eye on peak current drain is an important requirement for engineers, whenever you need to manage to a tight power budget. RIGOL’s DM3068 offers several features to help monitor over time. RIGOL DM3000-series – see the video below – all come with very capable MATH and STAT functions which will easily keep data like Max Current Drain displayed on-screen.

DM3068 rigol

These and other computed functions can be used on any measurements: Volts Amps Ohms as needed. There’s also a neat front-panel TREND line, with MAX & MIN figures still shown and a smart split-screen so you can easily see a zoom-view of the most recent changes.

Today’s engineers often need demanding measurements over long time periods and over unpredictable sequences of operation. Telonic Instruments Ltd’s video shows the quick and simple set up needed to activate RIGOL’s powerful monitoring and tracking functions.

With its 6½ Digits DM3068 brings higher-resolution and more options to achieve more effective measurement and with excellent connectivity, plus logging software included as standard, RIGOL offers outstanding value


AC power supply boasts 4kW variable frequency

The PCR4000M, a 4kW variable frequency AC power supply, has been made available by Kikusui’s UK Distributor Telonic Instruments. The power supply expands Kikusui’s exisiting PCR500M, PCR1000M, PCR2000M and PCR4000M variable frequency (40-500Hz) AC power supplies.


The PCR4000M features AC, DC and AC+DC output, memory function, current limit and selectable start phase. Users are able to measure not only voltage, current and power of the AC and DC output, but also apparent power, reactive power, power factor, crest factor and current peak hold. Equipped with an RS-232C interface, the device comes complete with control/logging software as standard.

A number of options are available including GPIB, USB and an analogue input card which allows the frequency converters to be used as power amplifiers. Applications for the PCR4000M include avionics testing (400Hz 115VAC for seating, cabin electronics and audio visual products), measuring power factor on LED lighting and power adapter testing to simulate real world power conditions.

The PCR500/1000/2000M and 4000M are available for both purchase and hire from Telonic Instruments.

Spectrum analysers advance to 3.2GHz and 7.5GHz

Telonic Instruments has two high performance, higher frequency spectrum analysers, the DSA832-TG and the new DSA875-TG that push RIGOL’s DSA800 series to 3.2GHz & 7.5GHz, respectively. The spectrum analysers are available with Tracking Generator options up to 7.5GHz offering powerful and broad ranging features including options for VSWR measurement toolkit for configuring and evaluating antennas.

spectrum analysers

They also feature an advanced measurement kit (DSA800-AMK software) with numerous additional measurement functions including T-power, channel boundaries and CNR noise ratio.

New accessories include the 8GHz VSWR bridge or directional coupler (VB1080 2-8GHz) plus accessory packs for 75 Ohm work (RF CATV Kit), and attenuator sets for higher power work including the RF Attenuator Kit which includes 6 and 10dB attenuators or the model ATT03301H 30 dB high power attenuator.

Designed so you achieve Wi-Fi, Bluetooth, and many new comms/RF standards – SSB Phase Noise is down as low as -98 dBc/Hz (@10 KHz) – these new specs enable engineers to more accurately analyse modulations and noise surrounding their signals for increasingly critical debugging and immunity testing of transceiver systems. Using the 7.5GHz instrument, engineers can investigate the 3rd harmonic for all 2.4GHz applications. Additionally, resolution bandwidth settings down to 10Hz mean more precise visualisation of low power RF signals.

Using the instruments’ EMI-DSA800 option, designers can enable the EMI RBW settings and the Quasi-Peak filter across the entire spectrum of interest for compliance and immunity testing. The new preamplifier option (PA-DSA832 or PA-DSA875), assists with finding and evaluating even extremely low power issues. With this option, the displayed average noise level (DANL) normalized to 1 Hz is specified as low as -161 dBm (typical) from 5MHz all the way to 3.2GHz.

EMC probe set targets pre-compliance testing

A new EMC Probe set for pre-compliance testing from TekBox is available at Telonic Instruments.  This EMC Probe Set contains 3-off magnetic (H) field probes, 1-off electric (E) field probe, an adapter and RF cable. The H20, H10, H5 and E5 are magnetic field (H) and electric field (E) probes for radiated emissions EMC pre-compliance measurements.

Telonic probes

The probes are used in the near-field of sources of electromagnetic radiation. They serve to locate and identify potential sources of interference within the building blocks of electronic assemblies.

The probes act similar to wideband antennas, picking up radiated emissions from components, PCB tracks, housing openings or gaps and from any other parts that could be emitting RF energy. Scanning a probe over the surface of a PCB assembly or housing quickly identifies locations which emit electromagnetic radiation. By changing to a probe with a smaller size, the source of the emissions can be narrowed down further.

The probes can also be used for for RF immunity tests, by feeding a RF signal into the probe and radiating it into potentially susceptible areas of the circuit. Furthermore, the probes can be used for repair or debugging, to track down issues in RF circuits by non-contact measurement of RF signal levels.

Features include a slim design for good access in between tightly spaced components, shielded loops to avoid picking up common mode noise; insensitive to the human hand, a frequency brange of 3GHz, though they can be used well beyond, SMB connectors to avoid twisting the RF cable when scanning DUTs.

The probes are insulated with rubber coating.

Waveform generators feature five functions

The DG1000Z series of arbitrary/function waveform generators from Rigol help engineers to accomplish a wide range of testing applications by combining many functions in one easy-to-use instrument. Functions include arbitrary waveform generator, function generator, pulse generator, harmonic generator, and analogue/digital modulator.

waveform generator

The instruments, now available at Telonic Instruments, also incorporate Rigol’s Direct Digital Synthesiser (DDS) technology, ensuring that signals are delivered with stability, precision, purity and low distortion. These arbitrary waveform generators with innovative SiFi (Signal Fidelity) can generate arbitrary waveforms point-by-point and allow precisely adjustable sample rates and low jitter (200ps).

The arbitrary waveform memory is available with 8 Mpts (standard) and 16 Mpts (optional). Two full functional channels can be used as two independent generators offering ±1 ppm frequency stability and -125 dBc/Hz phase noise. The instruments have a built-in 8 orders harmonics generator and a built-in 7 digits/s full function frequency counter with 200MHz bandwidth.

Users can choose from up to 160 built-in waveforms with 14 bits vertical resolution and can benefit from a convenient arbitrary waveform editing interface. Versatile modulation types include AM, FM, PM, ASK, FSK, PSK and PWM. The instruments offer standard interfaces USB Host & Device and LAN (LXI Core Device 2011) and a 3.5“ TFT colour display. All models are supported by the Ultra Station PC software tool.
