Unless noted, all specificaTIons describe the instru-ments’ warranted performance under the followingcondiTIons: 5-minute warm-up from ambient condi-TIons, autocoupled controls, digital display, IF ADJON, REF LVL CAL adjusted, SECOND IF OUTPUTand 1ST LO OUTPUT terminated in 50 Ω. After a30-minute warm-up, and over a temperature rangeof 20 °C to 30 °C, the preselector does not have to be peaked at each signal of interest; under thesecondiTIons factory preselector peak values are suf-ficient to meet all specifications. Typical perform-ance is nonwarranted. Supplemental characteris-tics are denoted by “nominal” and “approximately”;these constitute nonwarranted functional perform-ance information derived during the designprocess and are not tested on a continuing basis.
