(b) MODE switch to AUTO.
(c) TIME-SECONDS vernier control fully cw.
(d) MARKERS switch to OFF.
(2) Connect power meter to RF OUTPUT, using attenuator (fixed).
(3) Press CW pushbutton and set POWER LEVEL and SLOPE controls for
maximum leveled power out.
(4) Set PEAK control to mechanical center, and slowly rotate CW control through
the lower portion of band while observing power meter readings. If minimum power is not
greater than +5 dBm, with variations of less than 0.8 dB, perform b (1) below.
(5) Rotate CW MARKER control through the upper portion of BAND while
observing power meter reading. If power meter does not indicate more than +5 dBm with
variations of less than 0.8 dB, perform b (2) below.
(6) Repeat (1) through (5) above for BAND 2 and BAND 3, using appropriate
hardware for the frequency range. If power meter does not indicate more than +5 dBm,
perform appropriate adjustments in b (3) through (6) below.
