(9) Increase function generator amplitude until TI indicates a stable display. If
signal output exceeds 100 mV rms and, if not previously performed, perform b (1) through
(6) below.
NOTE
Omit (10) through (16) below when calibrating model 5326C.
(10) Connect function generator to INPUT B jack.
(11) Position controls as listed in (a) through (f) below.
FUNCTION switch to T.I. A to B.
(a)
CHK-SEP-COM switch to SEP.
(b)
A SLOPE switch to + (positive).
(c)
B SLOPE switch to - (negative).
(d)
TIME BASE/MULTIPLIER switch to .1 s.
(e)
A and B LEVEL controls to midrange.
(f)
(12) Set function generator frequency to 50 MHz and minimum amplitude; slowly
increase amplitude while adjusting B LEVEL control until channel B trigger light
illuminates. If function generator output amplitude exceeds 100 mV rms, perform b (1)
through (6) below, using adjustments on (A3) circuit board.
(13) Connect signal generator to INPUT C jack.
(14) Turn FUNCTION switch to FREQ C and TIME BASE switch to 1 ms.
(15) Set function generator frequency to 50 MHz and amplitude to minimum.
(16) Slowly increase function generator amplitude until TI displays stable indication
TI's with SN prefix 1128A and below), perform b (7) below.
b. Adjustments
NOTE
If calibrating INPUT B, set FUNCTION switch to FREQ A
and LEVEL B control to PRESET. Perform adjustments on
A3 circuit board.
(1) Connect equipment as shown in figure 2.
