MHz
keys are NOT used with the 11974 Series.
SHIFT
,

selects the first millimeter frequency “lettered” band, K-band
(18 – 26.5 GHz). (Note: K-band is not available in the 11974 Series.)
Each succeeding press of the
⇑
key advances to the next lettered
band. For example, A band can be displayed by pressing
SHIFT
⇑
⇑
.
The lettered bands are paired with harmonic numbers. Due to some
overlap between bands, always enter the millimeter band by using
the
SHIFT
⇑
keys to select the lettered band. Do not enter in the
center frequency of the band directly.
SHIFT
,
GHz
calls the preselector-peak DAC number to the active function. The
DAC provides a vernier offset to the TUNE + SPAN to account for
slight preselector mistracking with time, temperature, and so on. For
the 0 to 63 DAC number range, the frequency range is approximately
n times 46 MHz, where n is the harmonic number. The DAC number
is saved with instrument preset (IP), but it is not saved using the
SAVE/RECALL function or with a learn string.
SHIFT
,
5
,
MHz
calls CONVERSION LOSS to the active function. This is a
single-point amplitude correction for each millimeter band, and each
band's conversion loss is saved with IP, when the band is exited, and
with the SAVE/RECALL functions.
SHIFT
,
2
,
MHz
calls the FULBAND number to the active function. This is an
alternative function to
SHIFT
,
⇑
,
⇑
in which each millimeter lettered
band can be entered by a FULBAND number. For example, A band is
equivalent to FULBAND 7, Q band is equivalent to FULBAND 8,
and so on.
SHIFT

displays the

key menu on the display screen for reference
purposes.
