P6701B and P6703B Specifications
The specifications in Tables 1 through 3 apply to a P6701B or P6703B O/E
converter. The converter must have a warm-up period of at least 20 minutes and
be in an environment that does not exceed the limits described in Table 1.
Specifications for the P6701B and P6703B O/E converters fall into three
categories: warranted, typical, and nominal characteristics.
Warranted Characteristics
Warranted characteristics (Table 1) describes guaranteed performance within
tolerance limits or certain type-tested requirements. Warranted characteristics
that have checks in the Performance Verification section of the service manual
(070-9892-XX) are marked with the n symbol.
