General settings

Operation mode

General settings 1:

Pre-trigger (R32.8-10)

Recording ceases as soon as a trigger event occurs.

Mid-trigger (R32.8-10)

The trigger event is the center of the recording.

Post-trigger (R32.8-10)
default

Recording commences as soon as a trigger event occurs.

Fast sampling (R32.8-10)

Operation with increased sampling rate of up to 10 µs:

  • The recording can only be started via the trigger input.
  • The settings of the trigger units are not taken into account.
  • Only the first channel is recorded, even for KL3362.

Trigger delay active (R32.4)
default: not activated

Switches the trigger delay on.

Trigger delay (R52)
default: 0

A trigger delay (tTD) can be specified here. The number of skipped samples (nSTD) is entered as the parameter. The trigger delay thus depends on the sample rate! Sample:
- Sample Rate: Ts = 200 µs
- Skipped Samples:  nSTD=100
tTD = Ts x nSTD = 200 µs x 100 = 20 ms

Test mode active (R32.5)
default: not activated

Switches the test mode on. In test mode, a ramp is output instead of converted analog values. It runs from 0 to 0x3FFF and back again.

Auto-trigger active (R32.6)
default not activated

Switches the auto trigger function on. With auto trigger switched on, the trigger unit is automatically activated once the preceding event has been evaluated. To this end, bit 0 is toggled in status register 1 (SR1) with each new evaluation.

General

 

General settings 2:

Sample rate (R35)
default: 200 µs

Interval (Ts) between two samples (scans) in microseconds.
The sampling speed is limited to Ts =100 µs (10 kHz) by the evaluation of the trigger detectors.
Only the Fast sampling mode enables sampling at Ts =10 µs (100 kHz).

Sample amount (R36)
default: 100

Number of sampling values to be recorded. A maximum of 4,000 values can be recorded.

Trigger frequency (R56)
default: 0

Here you can specify the trigger frequency of the timer.

Scaling channel 1

General settings 3:

User offset (R33)
default: 0

Here you can enter an offset. Scaling:
offset = full scale value x parameter / resolution

Sample for KL3361: 16 mV x 100 / 32767 = 0.049 mV

User gain (R34)
default: 256

Here you can enter the gain factor for scaling the input value by this factor.

Scaling channel 2 (KL3362 only)

General settings 4:

User offset (R33)
default: 0

Here you can enter an offset. Scaling:
offset = full scale value x parameter / resolution

Sample for KL3361: 16 mV x 100 / 32767 = 0.049 mV

User gain (R34)
default: 256

Here you can enter the gain factor for scaling the input value by this factor.
