Specifications characterize the warranted performance of the instrument under the following operating conditions:
Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C ambient temperature. Typical specifications are not warranted.
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.
All voltages are specified in DC, ACpk, or a combination unless otherwise specified.
Clean devices and terminal blocks by brushing off light dust with a soft, nonmetallic brush. Remove other contaminants with a soft, lint-free, dampened cloth. Do not use detergent or chemical solvents. The unit must be completely dry and free from contaminants before returning to service.

Insertion loss thermal coefficient |
α = 1,112 ppm/°C |
Use the following equation to calculate the insertion loss at a given temperature:
where | IL is insertion loss in dB |
T is the temperature at which the property is being measured in °C | |
T0 is the reference temperature in °C | |
α represents insertion loss temperature coefficient in ppm/°C |
Frequency | Flatness / 200 MHz | Flatness / 1GHz |
