as complementary signals to the HPL and HPR outputs. In these complementary configurations, the COM
outputs can be selected as differential signals to the corresponding outputs or may be set to be a common
mode voltage. When used in these configurations, the power button for the COM output is disabled, as the
power mode for that output will track the power status of the HPL or HPR output that the COM output is
tracking.
At the right side of the output strip is a master volume knob for that output, which allows muting the output
or applying gain up to 9dB.
A simple scripting language controls the TAS1020 on the USB-MODEVM from the LabView™-based PC
software. The main program controls, described previously, do nothing more than write a script which is
then handed off to an interpreter that sends the appropriate data to the correct USB endpoint. Because
this system is script-based, provision is made in this tab for the user to view the scripting commands
created as the controls are manipulated, as well as load and execute other scripts that have been written
and saved (see
). This design allows the software to be used as a quick test tool or to help
provide troubleshooting information in the rare event that the user encounters problem with this EVM.
