Output ramping Advanced features
Move the cursor to the trigger response selection (using the RIGHT
selection key or the ENTER key) and select the response to be RAMP I
or RAMP V (use the UP / DOWN selection keys).
Move the cursor to the ramp duration entry field (use the RIGHT
selection key or the ENTER key) and enter the desired duration (see
below).
How to enter ramp duration
Ramp duration is programmed by flipping the value (incrementing / decrementing)
using the UP / DOWN selection keys.
Place the cursor (using the RIGHT / LEFT selection keys) under the digit you wish
to flip. The digit you select determines the amount added or subtracted from the
duration as you flip it.
As you flip the ramp’s duration you may notice that the duration is set in units of 6
mili-seconds, therefore the change in value will be a multiply of 6.
ARM and Set final state
Finally, prepare the power module for ramp initiation:
Select the SET parameter (move the cursor to the parameter’s name and
use the up / down selection keys).
Press the STO key to arm the power module.
Move the cursor to the voltage or current entry field (use the RIGHT
selection key or the ENTER key) – depending on the type of ramp you
wish to initiate.
Set the final value for the ramp operation. If the value you program is
lower than the initial value, you will generate a down-ramp. If the value
you program is higher than the initial value, you will generate an up-
ramp.
Press SET to exit programming mode or proceed to trigger the power
module.

initiation
Once the ramp operation is setup the Power Module is waiting for a trigger in order
to start ramping its output.
The trigger can be supplied to the Power Module using one of the following
methods:
Hardware trigger – TRIG input at the rear panel.
Manual Power Module trigger – using the front panel.
To trigger the power module using the front panel proceed as follows:
If you are no longer in programming mode:
o Select the power module to program (see: first operation steps
chapter for details).
o Select the LOAD, OUT or SET parameter (use the up / down
selection keys) and enter programming mode (press the SET key)
or enter programming mode and then select the SET parameter
(see: Programming power module parameters in the basic
operation chapter).
Press the RCL key. A trigger is generated and the ramp operation
commences.
