a. Performance Check
(1) Position controls as listed in (a) through (g) below:
(a) COM-SEP-CHK switch to SEP.
(b) A and B ATTEN switches to X1.
(c) A and B AC/DC switches to DC.
(d) A and B SLOPE switches to +.
(e) A and B LEVEL controls ccw to PSET.
(f) Function switch to 10S.
(g) DELAY switch ccw to OFF.
(2) Connect function generator output to TI A INPUT, using termination.
to minimum output.
(4) Slowly increase function generator amplitude until measuring system indicates
a stable count of the applied frequency. If function generator output exceeds limit specified
in first row of table 12, perform b (1) through (3) below.
(5) Repeat technique of (3) and (4) above at remaining function generator
frequencies listed in table 12. If function generator output exceeds limit specified in
table 12, perform b (1) through (3) below.

(6) Set TI function switch to AUTO and repeat technique of (3) and (4) above at
function generator frequency of 10 MHz. If function generator output exceeds 50 mV and
no adjustment was previously made, perform b (1) through (3) below.
