Recording Modes
In this window, you can define the recording time, pre triggers, and hold off time for all
the virtual measuring instruments.

The meaning of the parameters can be seen in the graphic on the top of the panel. The
picture changes dynamically depending on the settings and is always related to the virtual
instrument that has the focus.
With the two check-boxes in the continuous recording section you can select continuous
measurement for rms and harmonics. When you check this, the shortest rms averaging
time is 200 ms.
For transient recordings, you can enter sampling frequencies between 100 kHz and
10 MHz. Please note that the recording time depends on the sampling frequency. The
maximum number of samples per recording is 262144. This results in maximum
recording times of 2.62 s with 100 kHz and 26.2 ms with 10 MHz.
After setup, you can switch the presentation in the bottom of the panel from Time to
Values / Samples to check the number of values that will be recorded.
Note
The transient option is only available if it is built into the instrument. No
error message is issued if an invalid sampling frequency is selected.
