Set
BANDWIDTH
(
10
) to 250 kHz. Set the
SCANWIDTH
(
15
) to 50 MHz/div. After the center
frequency is set to 250 MHz, a generator signal must be
applied to the input. The output level should be between
40 and 50 dB above the noise.
C:
Set generator frequency to
250 MHz
. Adjust the peak
of the 250 MHz spectral line to the horizontal screen
center using the
X-POS.

).
D:
Set the generator frequency to
50 MHz
. If the 50 MHz
spectral line is not on the 2nd. graticule line from left, it
should be aligned using the
X-AMPL.

). Then
the calibration as described under
C
should be verified
and corrected if necessary.
The calibrations
C
and
D
should be repeated until
optimum adjustment is achieved.
