4395A

Agilent 4395A Network/Spectrum/Impedance Analyzer Data Sheet Network Measurement Specifications describe the instrument’s warranted performance over the temperature range of 0 °C to 40 °C (except as noted). Supplemental characteristics are intended to provide information that is useful in applying the instrument by giving non-warranted performance parameters. These are denoted as SPC (supplemental performance characteristics), typical, or nominal. Warm up time must be greater than or equal to 30 minutes after power on for all specifications.
