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.
- Free insured delivery to your UK mainland address (sales).
- Support from our team of seasoned Test & Measurement engineers.
- ISO9001 quality assurance.

Technical Specifications
January 2007
Specification: describes a guaranteed product performance that is valid under the specified conditions. Specifications are
based on a coverage factor of 2 (unless otherwise stated), corresponding to a level of confidence of >95%.
Typical value: a characteristic, describes the product performance that is usually met but not guaranteed.
Generally, specifications are valid after warm-up, after zeroing, in auto-range mode (if not differently stated) and at the
stated operating conditions and measurement settings.

• Ambient temperature 23 °C ± 5 °C
• On day of calibration (add ± 0.3 % for aging
over one year, add ± 0.6 % over two years)
• Spectral width of source
<10 nm (FWHM)
• Wavelength setting at power sensor must
correspond to source wavelength ± 0.4 nm
• Humidity 50 % ± 10 %

Operating Conditions:
Parallel beam, ∅ 3mm , center of sphere
input, or connectorized fiber with NA ≤0.2
(straight connector)
• For NA > 0.2: add 1%
• Within one year after calibration, add
± 0.3% for second year
• Operating temperature range as specified,
humidity <80% and non-condensing
• Zeroing required

wavelength (1550 nm ± 30 nm) and constant

Thermal drift at 38 dBm,

[7]
For optical power > 30 dBm the maximal
operating temperature is limited to 35°C
[8]
Wavelength must not be equal to any water
absorption line
Safety Note:
For optical power higher than 34 dBm the attached heat sink MUST be used!
For continuous optical power or average optical power higher than 38 dBm the connector adapters will get warmer than permitted
according to the safety standard IEC 61010-1.
The 81628B Optical Head can handle optical power up to 40 dBm, however, operation above 38 dBm is at the operators own risk.
Agilent Technologies Deutschland GmbH will not be liable for any damages caused by an operation above 38 dBm.
