Agilent 83440C

Specifications and Characteristics

Specifications describe the instrument’s warranted performance over the temperature range

0 to 55°C (except where noted). Supplemental Characteristics are intended to provide information

useful in applying the instrument by giving typical but non-warranted performance parameters.

These are denoted as “typical,” “nominal,” or “approximate.”
