Impedance 50 ohm 75 ohm Other: Select either 50 ohm, 75 ohm, or
Other impedance value. Selecting 75 ohm selects the 7.5 dB loss of the
Anritsu 12N50-75B adapter. For other adapters, select Other and enter the
appropriate loss (0 dB is the default loss). Note that loss values are also
applied to the relevant units.
Bias Tee: Refer to Chapter 8, “Bias Tee (Option 10)” . See the product
Technical Data Sheet to check option availability on your instrument model.
Auto Ref Level: The Auto Ref Level function adjusts the position of a
signal on the display screen so that it is approximately two divisions down
from the top, if possible. When the key is pressed, the reference level is
adjusted once. Auto Ref Level may turn off the low-noise front-end
preamplifier, but does not turn it on. It has no effect on vertical scaling.
Back: Press this submenu key to return to the previous menu.
