ed in Step i. Set
the
Test
Oscillator’s meter switch

a zero reading on the Test Oscillator’s
meter.
Use the
Test Oscillator’s
level
controls to maintain
this zero

whenever
the Test Oscillator frequency is
varied.
q.
1. Standard Model 3455A: Set the Test Oscillator
to 1 MHz (maintain reference
level
on meter of
Test Oscillator). The 3455A display reading
should be
within
the Test Limits
given
in
Table
4-5.
2. 3455A Option 001: Set the Test Oscillator
fre-
quency to
250 kHz (maintain reference level on
meter of Test Oscillator). The 3455A display
reading should be
between 0.99240 V
and
1.00760 V (24-hour
spec.)
or between 0.99190 V
and 1.00810 V (90-day spec.).
r. Set the 3455A FUNCTION to FAST
