PA5 Top Level Menu
Atten
Sets attenuation from 0.0 to 120.0 dB in 0.1 dB increments. The default setting is 0.0 dB. When
Atten is in use, the letter "A" appears on the left side of the display, while the attenuation level
appears on the right side of the display.
UserAtt
Sets attenuation based on UserOps settings. Before use, attenuation parameters must be set
up via the UserOps sub-menus (see below). The default setting is 0.0 dB. When UserAtt is in
use, the letter "U" appears on the left side of the display, while the attenuation level appears on
the right side of the display.
UserOps
Access UserOps submenu:
BaseAtt
Sets a
fi
xed level of attenuation as a reference. The default setting is 0.0 dB and the range is 0
to 100.0 dB. When BaseAtt is set, a "+" symbol appears on the left side of the display.
When used, the attenuation level displayed is relative to BaseAtt. For example, with BaseAtt set
to 60.0 dB, the attenuation level will be display from -60.0 dB to 60.0 dB.
StpSize
Sets the increments of attenuation. The default setting is 3.0 dB, and the range is 0.1 to 60.0
dB.
Refrnce
Changes the display so it shows the output signal intensity rather than the attenuation level.
This function may be used only when the input signal strength is known. When Refrnce is set,
the letter "R" appears on the left side of the display. The default setting is 0.0, and the range is
± 300.0.
For example, when Refrnce is set to 136 and the attenuation level set to 0.0 dB, the display
shows 136.0. When the attenuation level is adjusted to 30.0 the display shows 106.
