Transient Recorder

Instrument task bar

The transient recorder is the ideal instrument for measuring slowly changing signals like the temperature change in a room or the movement of objects. The transient recorder is a direct recording instrument. This means that each measured sample is displayed immediately. An oscilloscope first has to fill a complete record and then displays the record, resulting in long waiting times when a slow sampling speed is selected.

    PC measurement software - Transient Recorder

The transient recorder can sample with sample times between 0.01 sec and 500 sec. The maximum number of samples is 32760/65520/131060 (depending on the instrument), resulting in a maximum measurement time of almost 190/380/758 days.

While measuring, each sample is displayed in one display pixel. When the number of samples is larger than the display width, two different methods can be used to display the next sample: scan mode and roll mode. With scan mode, the screen is cleared and filled again from left to right. With roll mode the trace will shift through the display from right to left.

Apart from the features mentioned above, the transient recorder is quite the same as the oscilloscope:

  • 32K/64K/128K samples on screen without loss of information
  • easy time axis zoom using scaleable scroll bar slider
  • vertical offset and gain adjustable with graphically shiftable and scaleable axis
  • a convenient speedbutton tool bar
  • extended cursor measurements
  • all settings accessible through popup menus
  • storing and recalling reference signals
  • easy to use speedbutton toolbar for easy access of all functions
  • comment tags to mark specific events in the signal
  • colour hardcopy supported
  • explanatory comments with all controls

The extensive possibilities of the cursors can be used to analyze the measured signal. Besides the standard measurements, also True RMS , Peak-Peak, Mean, Max and Min values of the measured signal are available.

An AUTO DISK function is available which can capture unexpected disturbances. When the instrument is set up for the disturbance, the AUTO DISK function can be started. Each time the disturbance occurs, it is measured and the measured data is stored on disk. When pre samples are selected, both samples before and after the moment of disturbance are stored.
