The recording and playback system
General
The high-speed recording system of the D1000X can also be configured to act as a time
expansion system. High-speed playback is also possible with the D1000X. In addition to
recording the ultrasonic signal directly, recording from the heterodyne and frequency division
systems is also possible. This is done at a lower sampling rate (44.1 kHz) to save CF card
space. Spoken comments can be recorded using the detector’s microphone either in the
normal, full-speed recordings (using the MIC key) or at reduced sampling rate (32 kHz) as
special, commentary files (using the COM key). The choice of recording source is made by
pressing the desired recording key; MIC, COM, HET or FD. Only one signal can be recorded
at each time.
When a COM recording is made, the selected recording parameters (PRE and POST values)
are overridden and the recording is started by pressing the COM key and stopped by pressing
it a second time.
The recording parameters
The recording system is controlled by a number of parameters that can be changed in the
settings menu or by assigning the desired values in externally created profiles.
If the CF card in the D1000X has a file with external profiles, the user will be prompted at
power-on of the D1000X whether to use the external or internal set of profiles. If you confirm
the question “LOAD INI-FILE?” by pressing the ENTER key, the set of external profiles is
loaded into the D1000X from the CF card. To load the internal, default profiles instead, press
the UP or DOWN ARROW key to display the text “LOADING DEFAULTS” and confirm
this by pressing ENTER.
The recording parameters are:
Recording mode – MAN or AUTO
Sampling frequency (sampling rate)
Time expansion factor
Replay mode
Save mode
Pre/post trigger time
Trigger source
High-pass filter – ON or OFF
LED and LCD backlight intensity
To change the recording parameters of the current profile, press ENTER while the detector is
in its standard mode. To navigate between parameters, use the UP/DOWN ARROW keys.
Press the ENTER key to select a parameter, use the UP/DOWN arrow keys to change its
value and then press ENTER again to lock it in. When you are pleased with your recording
parameters, they should be saved by selecting SAVE at the bottom of the settings menu and
pressing ENTER.
In order to leave the settings menu without saving, press the ESC key.
