during certain measurements.
IBASIC Instrument BASIC is the
computer language (code or software) used
by the test set’s built-in controller. The
IBASIC software is downloaded from the
OTP CARD into the test set’s RAM. This
software is then used to control the test set
during autotesting the unit-under-test.
