The first field can be set to " > " (greater than) or " < " (less than). If
you place the cursor on this field and press SELECT, it toggles
between > and < . The second field specifies the duration of the
pattern. If you select > in the first field, you can set the duration to a
value between 30 ns and 10 ms. If you select < in the frost field, you can
set the duration to a value between 40 ns and 10 ms. If you attempt to
set the duration to a value outside the given range, the analyzer will
automatically set it to the nearest limit.

second field and either press SELECT to get a pop-up menu, or just
press one of the numeric keys on the front-panel keypad. Both methods
