16.5.4. Example
Recording mode
Following example shows how to setup the device and start acquire data.
set_filter 80 350 8\n
// set 8th order bandpass 80-350 kHz
set_acq thr 1000\n
// set threshold to 1000 µV / 60 dB(AE)
set_acq ddt 400\n
// set ddt to 400 µs
set_acq cont 0\n
// disable continuous mode
set_acq tr_enabled 1\n
// enable transient data
set_acq tr_decimation 2\n
// set TR decimation factor to 2 -> 1 MHz
set_acq tr_pre_trig 200\n
// set TR pre-trigger samples to 200 = 100 µs
set_acq tr_post_dur 200\n
// set TR post-duration samples to 200 = 100 µs
set_acq status_interval 1000\n // set status interval to 1000 ms = 1 s
set_cct interval 0\n
// disable CCT / pulser
start_acq\n
// start data acquisition
// wait a little bit
get_ae_data\n
// retrieve hits and status data

// stop data acquisition
Logging mode
Following example shows how to setup the device for logging mode and read out the data from the internal
memory afterwards.
set_datetime 2020-09-29 08:29:50.301\n // set current date and time
…
// set acquisition settings
clear_data_log\n
// clear logged data from internal memory
set_data_log enabled 1\n
// enable logging mode
start_acq\n
// start acquisition in logging mode
// or: unplug spotWave and power on again
…
stop_acq\n
// optional: stop acquisition
get_data_log\n
// read all logged data from internal memory
