The event recording can be later exported from the logger
file to the PCM format.
Wave recording results are saved in a file with automatically defined name, which consists of a prefix (a
string of letters) and a number (string of digits). Name of the new Wave file is generated on the inherit
principle – new file name has the same prefix as the previous file, but it’s number is increasing by one.
Note: The Station(s) configuration window doesn’t allow to change the name of the Wave
files. But you can do it in the SVAN Files window with the help of Setup file editor function
– see “SvanPC++ User Manual”.
Note: PCM audio recordings take up a lot of storage space and also transmission bandwidth
during data downloading.
Recording settings
The Recording settings section enables choosing a sampling frequency and a format (only available
in the Wave recording mode) of the recording.
It is possible to select one of the three sampling rates: 12 kHz, 24 kHz or 48 kHz. Higher sampling rate
ensures recording of higher resolution but at the same time increases file size.
The Format position enables selecting the format of the
recorded file: PCM or Extensible.
The Bits per sample position enables selecting 16 or 24 bits
per sample.
Trigger parameters
The Event Trigger position enables selecting the recording
trigger type.
Triggering is switched on if one of its seven available types is
selected: Continuous, Slope +, Slope –, Level +, Level –,
Gradient + or Integration period (see Chapter 8.4.1).
When the Continuous trigger is active, whole measurements
will be recorded.
9.8.6 CSV export
The CSV export functionality allows direct export of measurement data into CSV files stored on the
instrument’s SD-card. The Current results tab enables selecting results to be exported from each
profile individually. Maximum, minimum and average spectra for each integration period can also be
exported.
