Introduction Specifications describe warranted performance over the temperature range of 0°to 45°C (except where noted) and include a 30-minute warm-up from ambient condi- tions, automatic calibrations enabled, auto-zero on, time domain calibration off, and anti-alias filter in, unless noted otherwise. Supplemental characteristics identified as “typical” or “characteristic,” provide useful informa- tion by giving non-warranted performance parameters. Typical performance is applicable from 20°to 30°C. When enabled, automatic calibrations are periodically performed to compensate for the effects of temperature and time sensitivities. During the calibration, no signals > 0 dBm should be connected to the front panel inputs.
