시설장비 설명 |
Unless noted all specifications describe the instruments’ warranted performance under the following conditions: 5-minute warm-up from ambient conditions autocoupled controls digital display IF ADJ ON REF LVL CAL adjusted SECOND IF OUTPUT and 1ST LO OUTPUT terminated in 50 Ω. After a 30-minute warm-up and over a temperature range of 20 °C to 30 °C the preselector does not have to be peaked at each signal of interest; under these conditions factory preselector peak values are sufficient to meet all specifications. Typical performance is nonwarranted. Supplemental characteristics are denoted by “nominal” and “approximately” these constitute nonwarranted functional performance information derived during the design process and are not tested on a continuing basis. |
