How to define the duration and sample rate for recording:
1. Select the desired time base in the time base list field.
a) The current setting of the time base multiplied by 10 results in the recording time.
b) As the size of the measured data memory in the inverter is limited, a compromise is usu-
ally made between sample rate and recording time.
2. Either enter the desired sample rate in [ms] in the sample rate input field or open the "Sam-
ple rate selection" dialog by clicking the "Sample rate" button and select a sample rate <
1 ms.
a) The sample rate in the inverter is automatically corrected to integer multiples of 62.5 µs.
Thus, the duration and sample rate are defined for recording and are considered when the
oscilloscope is started.
Defining the trigger condition
Based on the trigger condition, define the starting time of recording in the inverter. The oscil-
loscope offers various trigger conditions which serve to control the recording of the measured
values.
The trigger threshold can be changed in the "Value" input field on the "Settings" tab if the
channel is selected in "Signal source" that contains the corresponding parameter.
Setting Function
Signal source Selection of the trigger source:
Channel Triggering takes place on a channel configured in the "vertical channel settings" list
field.
immediate trigger No trigger condition, recording takes place immediately after the start.
Value Value, from which onwards triggering is caused.
Deceleration Time delay of recording with regard to the trigger event.
Pre-trigger When entering a negative delay time, you can detect signals that occur before the
trigger event.

Trigger level
The trigger time is marked with a dashed line in the oscillogram.
If it is triggered on the occurrence of an event, values caused by the event can be
detected in this way.
Post-trigger When entering a positive delay time, you can detect signals that occur a certain time
after the trigger event.

Trigger level
Edge Two trigger types are available:
increasing First, the value must fall below the defined trigger value and then exceed it in order
that triggering is activated.
decreasing First, the value must exceed the defined trigger value and then fall below it in order
that triggering is activated.
