HEAD News Herzogenrath (Germany), March, 2014
SQuadriga II 1.9 - The new firmware
Discover the benefits of the new firmware for SQuadriga II, which optimizes recording, playback, real-time analysis, the operation of the front end, and more.
All analyses can now be applied during playback. The new keypad/screen locking feature ensures secure handling of the front end and helps you to avoid operating errors while taking measurements. Furthermore, the DBCFile view graphically displays quantities currently present on the bus.
We are committed to making your workflow more intuitive and efficient with each new firmware version.
The new version is now available for you in the    Download Center.
 
Play & Record
The Play & Record function allows signals to be recorded simultaneous to the playback of other signals. With the Play loops setting, you can extend the recording time to multiples of the playback signal file length. Under Record delay, you can specify a delay that initiates the recording after a defined period from the start of playback. This allows you to avoid the zero signal and transient effect at the beginning of the recording.
 
Level, Loudness and Sharpness vs. Time
The scope of real-time analysis functions has been extended by Level, Loudness and Sharpness vs.Time. These analyses are FFT-based. They show the respective quantities over the last few seconds. The maximum time period that can be configured is 60 seconds. The axis of specific loudness can now be switched between Bark and Hz.
 
Analysis of the playback signal
All analyses can now be applied during signal playback of recorded files. You can start the playback analysis from the playback view. You can also enable filtered playback with the IIR filter function.
 
USB mass storage
You can now read and write files without the need to remove the SD card. By selecting a new ”SD-PC“ menu item, a new ”USB mass storage device“ screen is opened and the SQuadriga II is automatically unregistered from the computer as a front end and is registered as a mass storage device. Conversely, closing out the ”USB mass storage device“ screen unregisters the storage device to return to normal front end operation.
 
Display of CAN, pulse and GPS quantities vs. time
From the CANChannel, PulseChannel and GPS views, you can launch a new graphical display of the signals, which were previously displayed as numeric values only.
 
Keypad/screen lock
There are two possibilities to lock the user interface: Either the locking affects all functions except for the REC key, so recordings can still be started and stopped, or the entire system is locked to prevent recordings from being stopped accidentally.
