Configuration for Analog Measurements

  1. Configure at least one analog channel for data acquisition.

The measurement file size depends on the record length value and number of available channels. The maximum capacity of one measurement file is limited by the internal memory. The recording time for each channel is calculated by: recording time = record length value/sample rate.

The total recording time is determined by the earliest measurement start trigger of a channel to the measurement end of the last channel in the configuration.

Note

Make sure to configure the right analog mode for each channel. Take care that the sample rate is in relation to the maximum measured frequency.

Start conditions for each individual channel:

  • Instantly: Starts measurement instantly after setting input EN to TRUE.
  • Delayed: Measurement will start when input EN was set to TRUE and the start condition value [samples] is over.
  • Digital input: Starts the measurement when input EN and the digital input was set to TRUE.
  • Zero input: Starts the measurement when input EN was set to TRUE and the input Z+ gets a rising edge.
  • Encoder value: Starts the measurement when input EN was set to TRUE and the start condition value is satisfied.

The start criteria of all analog channels in one measurement have to be in a 20 hour time window. Otherwise, the measurement is invalid and will be aborted.
