Using Spectrum Analyzer Features

External Keyboard

The external keyboard operation with the cable TV analyzer is similar to its

operation with a computer except for the following:

SCROLL LOCK and NUM LOCK are fixed and cannot be changed. Pressing

c-1

displays the keyboard mode on the cable TV analyzer screen.

The analyzer will not recognize the control characters or function keys.

The keyboard supports a 244 character recall buffer. The longest single item

is limited to 243 characters; subsequent characters are ignored. Using the

keys of the external keyboard to recall an item does not change

the buffer contents. Recalling an item and then pressing the

@FE)

key does

not store a new copy of the item in the recall buffer. If an item is recalled and

then modified, a new copy will be made in the recall buffer. Adding new data

into the keyboard line deletes the oldest data automatically.

When in command mode, the active line will append a semicolon to the

keyboard entry if the line does not end with a semicolon and it is fewer than

243 characters long.
