Instrument Specications
The specications listed in T able 1 range from those guaranteed by Hewlett-P ackard to those
typical of most HP 8753D instruments , but not guaranteed. Codes in the far right column
of T able 1 reference a specication denition, listed below . These denitions are intended
to clarify the extent to which Hewlett-P ackard supports the specied performance of the
HP 8753D .
S-1: This performance parameter is veriable using performance tests documented in the
service manual.
S-2: Due to limitations on available industry standards , the guaranteed performance of the
instrument cannot be veried outside the factory . Field procedures can verify performance
with a condence prescribed by available standards .
S-3: These specications are generally digital functions or are mathematically derived from
tested specications , and can therefore be veried by functional pass/fail testing.
T: Typical but non-warranted performance characteristics intended to provide information
useful in applying the instrument. Typical characteristics are representative of most
instruments , though not necessarily tested in each unit. Not eld tested.
