About These Specifications

Specifications characterize the warranted performance of the instrument under the following operating conditions:

Chassis is powered on

Calibration adjustment cycle maintained

50 Ω termination connected to unused I/O front panel connectors

Current product revision used

Specifications describe the warranted, traceable product performance over ambient temperature ranges of 0 °C to 55°C unless otherwise noted.

Typical values describe useful product performance beyond specifications that are not covered by warranty and do not include guardbands for measurement uncertainty or drift. Typical values may not be verified on all units shipped from the factory. Unless otherwise noted, typical values cover the expected performance of units over ambient temperature ranges of 23 °C ±5 °C with a 90% confidence interval.

Nominal values (or supplemental information) describe additional information about the product that may be useful, including expected performance that is not covered under Typical Specifications. Nominal values are not covered by warranty.

Insertion loss

a = 240 ppm/°C (thermal coefficient, typical)

Use the following equation to calculate the insertion loss at a given temperature:

I L_{T} = I L_{T_{0}} (1 + α (T - T_{0}))

where IL represents insertion loss in dB
T represents the temperature at which the property is being measured in °C
T0 represents the reference temperature in °C
a represents insertion loss temperature coefficient in ppm/°C
