Specifications - Tektronix 7D20 Operator's Manual

General Information-7D20
The electrical characteristics listed in Table 1-1 apply when the following conditions
are met : (1) Adjustment of the instrument must have taken place at an ambient
temperature between +20° and +30° C, (2) the instrument and its host mainframe
must be allowed a 20-minute warm-up period, (3) all specifications are valid at an
ambient temperature of 0° to +45° C, unless otherwise stated, (4) the instrument
must be in an environment that meets the limits described in Table 1-2 .
Any applicable conditions not listed above are expressly stated as part of that
characteristic . Environmental characteristics are listed in Table 1-2 and Physical
characteristics are listed in Table 1-3 .
