a. Signal frequencies above 18 GHz are prone to additional response errors due to modes in the Type-N
connector used. With the use Type-N to APC 3.5 mm adapter part number 1250-1744, there are nomi-
nally six such modes. These modes cause nominally up to
−0.35 dB amplitude change, with phase
errors of nominally up to
±1.2 ° .
b. The listed performance is the standard deviation of the phase deviation relative to the mean phase devi-
ation from a linear phase condition, where the RMS is computed across the span shown.
c. Option MPB is installed and enabled.

a. This table is meant to help predict the full-scale level, defined as the signal level for which ADC over-
load (clipping) occurs. The prediction is imperfect, but can serve as a starting point for finding that
level experimentally. A SCPI command is also available for that purpose.
b. Mixer level is signal level minus input attenuation.
c. The available gain to reach the predicted mixer level will vary with center frequency. Combinations of
high gains and high frequencies will not achieve the gain required, increasing the full scale level.
d. The mixer level for ADC clipping is nominally given by that for the default settings, minus IF Gain
Offset, minus 10 dB if IF Gain is set to High.
