Specifications

Specifications describe the performance of parameters covered by the product warranty. These values are only valid for the stated operating frequency, and apply over 0°C to +55°C unless otherwise noted.

95th percentile values indicate the breadth of the population (approx. 2 s) of perfor- mance tolerances expected to be met in 95 percent of the cases with a 95 percent confidence, for any ambient temperature in the range of +20°C to +30°C. In addition to the statistical observations of a sample of instruments, these values include the effects of the uncertainties of external calibration references. These values are not warranted. These values are updated occasionally if a significant change in the statistically observed behavior of production instruments is observed.

Typical describes additional product performance information that is not covered by the product warranty. It is performance beyond specifications that 80 percent of the units exhibit with a 95 percent confidence level over the temperature range of +20°C to +30°C. Typical performance does not include measurement uncertainty.

Nominal values indicate expected performance, or describe product performance that is useful in the application of the product, but are not covered by the product warranty.

The analyzer will meet its specifications when:

  • It is within its calibration cycle
  • Under auto couple control, except when Auto Sweep Time Rules = Accy
  • Signals measured <10 MHz have DC coupling applied
  • The analyzer has been stored at an ambient temperature within the allowed operat- ing range for at least two hours before being turned on; if it had previously been stored at a temperature range inside the allowed storage range, but outside the allowed operating range
  • The analyzer has been turned on at least 30 minutes with Auto Align set to normal, or, if Auto Align is set to off or partial, alignments must have been run recently enough to prevent an Alert message; if the Alert condition is changed from Time and Temperature to one of the disabled duration choices, the analyzer may fail to meet specifications without informing the user
