Generating a ramp signal
1 Select your desired output mode by pressing Voltage to enable constant
voltage operation or Current to enable constant current operation. (The
respective annunciator — CV or CC — will illuminate accordingly.)
2 Select an appropriate range by pressing Shift > Range. The maximum
amplitude end position will be limited by the range selected. (The
respective annunciator — S1 or S2 — will illuminate accordingly.)
3 If you want to fine- tune the ramp signal parameters, press Shift > Utility
to access the utility menu. See “Configuring the ramp signal
parameters” on page 122 for more information on configuring the ramp
signal parameters. Press Shift > Save to save the changes and Shift > Exit
to exit the utility menu.
4 Press Ramp Scan to select the ramp function. Ensure that the Ramp
annunciator is shown on the display.
5 Press to generate the ramp signal.
The typical ramp dwelling time per step in the U3606A is measured at
300 ms. A longer delay time should be expected if a high number of steps
is programmed. As an example, a 1000 step ramp signal will yield a
10 minute (1000 × 300 ms × 2) total dwelling time.
