DESCRIPTION
The QA-1000HC is a configurable analog supply
current monitor, designed for loadboard applications. Its
low internal resistance ensures its transparency (causing
only a negligible voltage drop when inserted into the supply
or ground path of the device under test). The module is
designed to be inserted between the DUT supply provided
by the ATE and the supply pin of the DUT or between
ground and DUT ground. The VDUT supply can be positive
or negative (VDD/VCC or VSS/VEE).
The QA-1000HC is designed to accurately measure analog (supply) currents up to 2A (upon demand
the range can be adapted to 100mA, 200mA, 500mA, 1A or 5A), thereby providing a high
measurement repeatability. The monitor has a bandwidth of 5MHz, offers a resolution of 300µA @2A,
and is capable to drive high capacitive loads up to 100uF. The resolution and performance of the
monitor is a function of the selected bandwidth and the value of the loading capacitance CL (the DUT
local on-pin supply decoupling capacitance).
The QA-1000HC has no digital control pins. It measures continuously and relies for further signal
processing and decision making on the capabilities of the mixed-signal ATE. The QA-1000HC
provides an analog output voltage, corresponding to the measured current. The figure shows a block
diagram of the QA-1000HC as well as a typical application diagram. The output has a 50Ω impedance
for optimum RF performance. The low resistive output can be customised when AF performance is
preferred.
The QA-1000HC consists of 2 active units, a
SUPPLY
measurement unit (MU) and a processing unit (PU). The
measurement unit is a fast and sensitive current
measurement device that converts the measured analog

current in a corresponding voltage. The processing unit is
configurable and provides amplification and filtering
functionality. The QA-1000HC has a low internal resistance
between its VDUT and DUT terminals, therefore the
voltage at the DUT terminal closely follows the supply
CL voltage applied at its VDUT terminal within a -7V to +7V
ATE
range. The QA-1000HC has a broad application range.
TEST VECTORS
Examples are the application to high-power ICs and during
voltage stress test applications. By using two QA-1000-HC
monitors, supply currents of analog DUTs with
(symmetrical) +/- supply can also be measured
simultaneously.
