Introduction & Specifications-318/338 Service
SPECIFICATIONS
Tables 1-1 through 1-3 list the electrical, environmental, and physical characteristics of
the 318, 338, 318S1 ,and 338S1 logic analyzers. The electrical characteristics are valid
for logic analyzers that have been adjusted as described in this manual (refer to the
Verification and Adjustment Procedures section). The instruments are adjusted at an
ambient temperature b20° to +30
°
C (+68
°
to 68
°
F), and are designed to operate
in an ambient temperature between 0° to +50
°
C (+32
°
to +122
°
F) after having warmed up
for at least 15 minutes.
