Performance Specification
The specification tables use the following abbreviations.
Performance Requirement (Req) .
All performance require-
ments in the specification tables are identified with
Req, and can be
assured by completing the Performance Check Procedure (1740A/
1750A/1760--Series Service Manual.) Allow a warm-up time of 20
minutes.
Performance requirements in the electrical specifications are valid over an
ambient temperature range of +20
° C to +30° C. The Performance Re-
quirement tolerances listed in the Electrical Specification are doubled over
the temperature range of 0
° C to +50° C, unless otherwise specified. Test
equipment used to verify Performance Requirements must be calibrated
and working within the limits specified in the Service Manual Equipment
Required List.
Reference Information.
Information that amplifies a performance
requirement or is of special importance is indicated by
RI. There is no
need to check these items to a specific tolerance.
Reliability
Mean Time Between Failure (MTBF)
The demonstrated MTBF goal is 40637 hours MTBF at 25
° C ambient,
which will be monitored from field failure reports.
Mean Time to Repair (MTTR)
The projected MTTR is 1 hour.
