8.2 Read-Out a Periodic Ramp – RAMP Function
Ramp-type signals can be used to test the dynamic performance
of devices to be calibrated, or entire measuring circuits. An
example would be performance of a control loop with a setpoint
specified via the analog setpoint input at the controller. The
instrument can be used to replace costly hardware and software
for the setup of long-term test bays with cyclical time sequences.
Parameters for the ramps depicted below:
• The following functions can be adjusted as output quantities:
voltage U, current sink I sink, current source I source,
resistance R or temperature temp (TC or RTD).
• A lower (Start) and an upper (
End) range limit can be selected
for each output quantity from within the overall range.
• Rise time t1 and decay time t3 are adjustable from 0 seconds
to 60 minutes.
• Dwell time t2 at the upper and lower range limits is adjustable
from 0 seconds to 60 minutes
• There are 2 ramp sequences:
– One-time only (
onCE ): t1, t2, t3
– Repetition (
repeat ): t1, t2, t3, t2, t1, t2, t3, 
