Test Equipment Solutions Datasheet

Test Equipment Solutions Ltd specialise in the second user sale, rental and distribution of quality test & measurement (T&M) equipment. We stock all major equipment types such as spectrum analyzers, signal generators, oscilloscopes, power meters, logic analysers etc from all the major suppliers such as Agilent, Tektronix, Anritsu and Rohde & Schwarz.

We are focused at the professional end of the marketplace, primarily working with customers for whom high performance, quality and service are key, whilst realising the cost savings that second user equipment offers. As such, we fully test & refurbish equipment in our in-house, traceable Lab. Items are supplied with manuals, accessories and typically a full no-quibble 2 year warranty. Our staff have extensive backgrounds in T&M, totalling over 150 years of combined experience, which enables us to deliver industry-leading service and support. We endeavour to be customer focused in every way right down to the detail, such as offering free delivery on sales, covering the cost of warranty returns BOTH ways (plus supplying a loan unit, if available) and supplying a free business tool with every order.

As well as the headline benefit of cost saving, second user offers shorter lead times, higher reliability and multivendor solutions. Rental, of course, is ideal for shorter term needs and offers fast delivery, flexibility, try-before-you-buy, zero capital expenditure, lower risk and off balance sheet accounting. Both second user and rental improve the key business measure of

Return On Capital Employed.

We are based near Heathrow Airport in the UK from where we supply test equipment worldwide. Our facility incorporates Sales, Support, Admin, Logistics and our own in-house

Lab.

All products supplied by Test Equipment Solutions include:

- No-quibble parts & labour warranty (we provide transport for UK mainland addresses).

- Free loan equipment during warranty repair, if available.

- Full electrical, mechanical and safety refurbishment in our in-house Lab.

- Certificate of Conformance (calibration available on request).

- Manuals and accessories required for normal operation.

EMI Precertification Test Receiver

ESPC has been derived from various

Rohde & Schwarz full-compliance receiver models and thus opens up versatile applications in the field of EMI precompliance. It is a budget-priced solution for emission tests at all stages of development and production of electrical products. With a view to obtaining the CE conformity mark, this test receiver will be used wherever

EMI tests become necessary prior to acceptance testing in order to minimize the risks involved and the time taken for full-compliance tests.

Featuring built-in preselection, ESPC is able to perform accurate interference measurements with pulse repetition frequencies (PRF) to as low as 10 Hz in line with CISPR 16-1. An overload detection system for the complete receiver signal path from the input through to the IF stages warns the user in case of erroneous measurements.

Preselection and overload protection ensure reliable and reproducible measurements which is a particularly important aspect in automatic test runs.

Incorrect EMI diagnostics at an early production stage cause high costs, delay the product launch and hence put at risk the return on high investment. If a product does not pass the compliance test for whatever reason, it is all the more important that the test receiver used for post-qualification is absolutely reliable so that rework can be performed within the shortest possible time and the compliance test repeated as soon as possible.

Special features of ESPC

• Large frequency range from

150 kHz to 1000 MHz

• Options for frequency extension to

9 kHz and 2500 MHz

• Parallel detectors for average, peak and quasi-peak reading

• Fast synthesizer: frequency resolution 10 Hz and 100 Hz

Powerful processor system

• Macros for automatic and semiautomatic test routines

• Automatic level calibration

• Measurement of voltage, field strength, current and pulse spectral density with display of relevant units

• Automatic consideration of frequency-dependent transducer factors

Since the ESPC has been designed for use in electrical and electronic industries to cover all stages of development and production, it offers a compact and economical solution in particular for

• development-accompanying EMI diagnostic measurements,

• pre- and post-qualification tests,

• production tests.

With the aid of fast prescan measurements and subsequent evaluation the

ESPC checks the equipment under test

EMC-compatible design in the development phase of a product prevents later cost explosion for EMC compatibility. The ESPC provides settings of scan, bandwidth, limit lines and correction factors of frequency-dependent accessories in line with the relevant standards and thus satisfies the main requirements in development for improving the product quality while saving time and money. The comparison with standard or user-defined limit values allows immediate differentiation between critical and noncritical emissions of the EUT. With the aid of a variable acceptance value, uncertainties in the test setup or production tolerances can be taken into account.

Due to the increasing number and higher frequencies of mobile radio services, useful and interfering emissions up to 2.5 GHz have often to be investigated although weighting of emissions in line with EN standards is specified up to a frequency limit of

1 GHz only. The ESPC provides an optional frequency range extension up to

2.5 GHz which can also be retrofitted.

The test receiver automatically selects the correct CISPR bandwidths for the relevant test frequency. In conjunction with firmware macros for automatic test routines, comparisons with limit lines, for instance to EN standards, can conveniently be made.

Complete tests at a keystroke

Using the FAST PRESCAN function and peak and/or average detectors, the critical ranges of the spectrum can be determined and, to minimize the measurement time, the final measurement then correctly be carried out at the critical frequencies with the aid of

Up to 22 different

• limit lines ands

• transducer factors can be stored in a built-in nonvolatile memory, ensuring high accuracy for every frequency step.

Production

Prototype

R & S

Users not specialized in EMI can also easily handle and carry out these reproducible test runs. The ESPC shows its true strength at the press of a single button and starts as a stand-alone unit measurement of

Time data reduction routines and quasipeak and average detectors. With this concept valuable measurement time can be saved which otherwise would be spent on ranges of no interest with low emission levels.

• RFI voltage

• RFI power

• RFI field strength.

Moreover, the following test routines are available:

• automatic frequency scan and

• frequency list measurements at up to 400 frequencies.

ESPC allows simple and time-saving performance of development-accompanying diagnostic measurements

A comprehensive test report can be output on a printer or plotter. This makes the ESPC an extremely useful tool in development.

The report contains all the information required for reproducible measurements such as comments and description, test receiver settings, graphs and final results.

The final results of RFI voltage measurements are listed with frequency and level for QP and AV values. Levels exceeding the limit line are marked by an asterisk, with phase and grounding being specified.

RFI voltage test to EN55022

Software-supported

EMI measurements

The Windows™ Software ESPC-K1 supplied with the ESPC supports EMI measurements in line with commercial standards. After setting of the measurement configuration and test parameters via pulldown menus, the results are displayed as graphs and lists on the screen of a PC. Following a prescan measurement, investigation and final measurement at the critical frequencies are made in automatic, semiautomatic interactive or manual mode. Marker and zoom functions facilitate analysis of spurious emissions. The ESPC is controlled via the IEC/IEEE bus.

The test results can be output as graphs or lists on printers supported by Windows  or as files. A complete

RFI voltage test in line with EN55022 is shown in the illustration.

Note: In conjunction with artificial mains networks the ESPC should always be used with the

Pulse Limiter ESH3-Z2 for safety reasons (see also recommended extras).
