6.7.2 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 set-up of long-term test bays with cyclical time sequences.
Parameters for the ramps are 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 fall time t3 are adjustable from
0 seconds
…
60 minutes.
•
Dwell time t2 at the upper and lower range limits is adjustable
from 0 seconds
…
60 minutes.
•
There are 2 ramp sequences:
– One-time only (
onCE
): t1, t2, t3
– Repetition (

): t1, t2, t3, t2, t1, t2, t3,
