FLUKE PM6681R Datasheet - Test Equipment Solutions Ltd

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.

PM 6681: the highest
performance timer/counter/
analyzer available
The PM 6681 from Fluke sets the
new standard for measurement
and analysis of time intervals,
frequency, phase and jitter. For
development, calibration or
challenging production test
applications, the PM 6681 is the
leader.
Check these key PM 6681
performance parameters, and
compare the new state-of-the-art
for yourself:
■ 50 ps single-shot time interval
resolution (1 ps averaged)
■ 1.25 mV vertical resolution
■ 300 MHz range, options to
4.2 GHz
■ 8k readings/s to internal
memory
■ 250 readings/s over GPIB
■ Continuous single-period
measurements at up to 40k
readings/s
■ Unique hold-off and arming
delay facilities to measure any
part of any complex signal
■ TimeView™ PC software for
time and frequency analysis
So for the ultimate performance,
choose the advanced PM 6681.
PM 6680B: the value leader
For applications that don't demand
the PM 6681's sheer performance,
check into Fluke’s PM 6680B.
This model offers a combination of
performance and price that makes
it today's undisputed value leader.
Key specs. are identical to the
PM 6681, except for:

Explanation
Calibration Adjustment Tolerance is the maximal tolerated deviation from the true 10MHz frequency after a calibration. When the
reference frequency does not exceed the tolerance limits at the moment of calibration, an adjustment is not needed.
Total uncertainty is the total possible deviation from the true 10MHz value under influence of frequency drift due to ageing and ambient
temperature variations versus the reference temperature. The operating temperature range and the calibration interval are part of this
specification.
