Date Of Calibration: 2 March 2011

Ambient Temperature: 23 ± 1 ° C Relative Humidity: 45 ± 10 %

REMARKS:

This certificate records the on-receipt calibration status of the instrument, the item was returned in this condition.If any measured value exceeds the specification, "Out-of-spec" is shown in the Status column.

If a measured value plus its uncertainty exceeds the specification, "Guardband" is shown.Note: Measurements shown in italics are not UKAS accredited but are included for completeness of the

calibration report. Where the uncertainty is not stated, it has not yet been determined.

The testpoints are those established by the manufacturing division's standards laboratory for the

special "Gold Cal". Results of the calibration status at shipment are available as an ASCII format datafile.

TEST DESCRIPTION:The 90-day specification has been used to define the absolute test limits in this certificate. They include the

original manufacturer's calibration uncertainty for NIST traceability as published in the product's

Calibration Manual 03458-90017:Dec2000.

A minimum warm-up period of 4 hours was allowed before testing. In accordance with themanufacturer's recommended practice, the appropriate "ACAL" routines were invoked before testing each

function. The Firmware version reported by REV? was 8.2

The value for CALNUM? reported by the 3458A PRIOR to testing was 55

and at COMPLETION of testing was 55

This certificate is issued in accordance with the laboratory accreditation requirements of the United Kingdom Accreditation Service. It provides traceability of

measurement to recognised national standards, and to the units of measurement realised at the National Physical Laboratory or other recognised national

standards laboratories. This certificate may not be reproduced other than in full, except with the prior written approval of the issuing laboratory.

Any quoted uncertainty refers only to the measured value and does not carry any implication regarding the long term stability of the instrument.

The reported uncertainty is based on a standard uncertainty multiplied by a coverage factor k=2, providing a level of confidence of approximately 95%.
