Cyclic Ramp
The cyclic ramp generation function is used to program a first linear variation in a direction
(increasing or decreasing) followed by a first step and then a second linear variation in a di-
rection opposite to the first variation followed by a second step.
When this mode is active, the
icon appears in the transmission window.
The
function key is used to launch an increasing cy-
clic ramp and the
function key is used to launch an
decreasing cyclic ramp.
The default parameters of this mode are displayed on the
left hand side of the transmission window. To change
these parameters, press ENTER or use the

menus.
The parameters of a cyclic ramp are:
L:
Minimum amplitude of the signal.
H: Maximum amplitude of the signal.
Tl: Duration of a decreasing ramp.
Tlh: Duration of an increasing ramp.
Th: Duration of the high step.
Thl: Duration of the low step.
No.: Number of cycles to be generated.
Delay:
Delay in seconds between launching the cyclic ramp and the start of transmission.
During generation of a cyclic ramp, a progress bar indicates the state of progress.
The function keys can be used to control generation:
•
The
key stops generation at any time.
•
The key suspends generation.
•
The
key commences or resumes generation.
•
An icon in the transmission window indicates suspended generation.
