Channel Scanner Mode (Option 27)

The Channel Scanner option provides the choice of a bar graph or a text display showing
the amplitude of selected channels for a given air interface standard. The interface settings
can be manually entered if none of the available air interface standards meet the measure-
ment need.
To select Channel Scanner mode, press the MODE key and use the up and down arrows to
highlight Channel Scanner and press ENTER.
FREQ/SPAN
The operating frequency range for Channel Scanner mode can either be set manually, or the
desired air interface standard can be selected from the Signal Standard list in the instru-
ment. When the frequency range is selected from the Signal Standard list, all frequency re-
lated parameters are automatically set to the appropriate values for that particular standard.
Start Freq — Enter a start frequency from 9 kHz to 3000 MHz using the Up/Down arrow
key, or the keypad and the appropriate soft key for Hz, kHz, MHz or GHz. Press ENTER to
accept the input.
Freq Step Size — The value entered here is the channel spacing. Enter a step size from 0
to 3000 MHz using the Up/Down arrow key, or the keypad and the appropriate soft key for
Hz, kHz, MHz or GHz. Press ENTER to accept the input.
Signal Standard ¾ Opens a menu of soft keys used to select the signal standard to be
used.
Select Standard ¾ Opens the signal standard menu, showing the currently selected signal
standards. Use the soft keys to navigate the list. Press the Show All soft key to show the
complete signal standard list. When the complete list is displayed, the currently selected
signal standards are marked with an asterisk. Press the Show Selected soft key to show
only the currently selected signal standards.
Start Channel ¾ Sets the channel information for the available standard. If the particular
standard has not been used before, the channel number will default to the lowest legal chan-
nel number for that standard. If that standard has been used before, the last used channel
will be the default.
Uplink ¾ Selects the bank of frequencies that correspond to signals sent from the client
transmitter to the base station.
Downlink ¾ Selects the bank of frequencies that correspond to the signals sent from the
base station to the client receivers.
Back ¾ Returns to the previous menu.
Channel Step Size ¾ This integer value tells the system how many channels to skip
when scanning. Enter a step size from 1 to 1023 using the Up/Down arrow key or the key-
pad and press ENTER to accept the input. Channel Step Size is especially useful when
channels overlap, such as CDMA and WiFi channels.
