Description - ComSonics CyberTek QUALIFIER User Manual

The ComSonics CyberTek Qualifier is a signal
level meter dedicated to the CATV installer. It
features the ability to easily choose for
evaluation any one of six pre-selected channels
from the full tuning range available. The
Qualifier meter makes measurements on the
chosen channel with a single keystroke,
showing the results on a backlight-capable
liquid crystal display (LCD).
The Qualifier meter's controls have been
simplified to make its operation as easy as
possible. The keypad has six function keys (F1
through F6), each capable of tuning a picture
carrier frequency and its sound carrier
frequency or a single digital channel in the 5
MHz to 860 MHz range. It also has arrow keys
for single step tuning the unit within this range.
There are keys to control the backlight feature
as well as for powering the unit on and off. The
LCD features the channel being measured, its
level readout, and the unit of measure. A light
bulb symbol appears when the backlight is in
use; a battery symbol appears when the battery
level is low. Unless the battery charge life is
nearing an end, a bar graph shows the relative
signal strength. When the battery symbol is
present, the bar graph indicates remaining
battery life.
