Option 8 allows storing the sound signal itself onto the SD card or the internal memory.

This option is especially useful for source identifi cation. The sound recording can be trigged by an external hand switch, by a level trigger (requires option 16) or by a manual key push.

Several recording formats are supported, ranging from 8, 16 or 24 bit and with sampling rates of 12 or 48 kHz. Using 48 kHz sampling and the stored sound signal may be used for further processing. The Nor140 has a large dynamic range – exceeding 120 dB. This means that if you try to play back the signal on your
PC you will – in most cases - hear nothing!

To overcome this problem a special digital gain, 0 – 96 dB, can be added to the sound recorded signal without affecting the calibration or measured values.

Another useful feature is that you may play a 10 sec reference tone - sine wave, pink or white noise in the beginning of a measurement to set a reference level when later replaying recorded data.

Option 8 requires that minimum option 6 be installed
