Frequency Specifications, Agilent 8560 EC Series
Unless noted, all specifications describe the instrument’s 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 non-warranted. Supplemental characteristics are denoted by “nominal” and
“approximately”; these constitute non-warranted functional performance information derived during the design process and are not tested on a continuing basis.
