circuits. The REN line is at logic one(O.8Y) when the

is displayed. The pulse stretcher
turns it OFF for a visible period of time if the REN
lines go to logic zero (2Y) for 2

line is at logical one (O.8Y), when the IFC annunciator
is displayed. The pulse stretcher turns it ON for a

1.4.5 The 488 Analyzer provides a terminal with 17
Test Points (TP) which parallels the GPIB connector.
The 18th TP provides the trigger

output

for peripheral

device. These TP connections expand the diagnostic

applications of the unalyzer. The lest point assignments
are listed in Table 3.5.

J.4.6 The 488 operates from a batte ry pack con-

taining 4 C-typc cells.
