DUT INSTALLATION
SOCKET PINOUT
A daughterboard arrangement is used to accommodate difference device packages
and bias conditions. A zero-insertion force (ZIF) socket accepts these daughterboards.
The AVRQ-5-B mainframe provides the high-voltage common mode pulse (which is tied
to GND1), and VCC2 / GND2 (the non-floating output-side power supply). The user is
responsible for configuring the daughterboards to implement the correct input side
power (VCC1), biasing, filtering, loading, socketing, and glitch measurement. The
included sample boards implement these requirements for common DIP8 devices,
using configurable jumpers/resistors/capacitors. A probe point is provided on the main
circuit board for observation of the device logic output with a user-provided probe and
oscilloscope.
The ground-referenced output-side power (VCC2) is generated by the mainframe, and
is adjustable (+3V to +43V, 150 mA maximum). The floating input-side power is not
provided by the mainframe. Instead, an A23-type 12V battery should be installed on the
DUT daughterboard to provide a floating power source, along with a basic regulator
circuit to provide the necessary reg5V power (VCC1). A isolated battery
arrangement is used to ensure that the VCC1 power supply is not the source of any
glitches observed in the operation of the DUT.
The AVRQ-5-B provides a zero-insertion force (ZIF) socket into which the
daughterboard may be plugged. The simplified circuit diagram of the ZIF socket on the
mainframe is shown below:
