7.1.3. DC1000 Tests
Test Description Main Application Winding Tested Reason for Test
LSBX*
Inductance with
External Bias
(Series Circuit) Wound components
that usually carry a
significant DC Bias
current in normal
operation. Selected Windings Checks number of
turns, right grade of
correctly assembled
core material, where
bias current is
greater than LSB test
can handle.
LPBX*
Inductance with
External Bias
(Parallel Circuit) Wound components
that usually carry a
significant DC Bias
current in normal
operation. Select Windings Checks number of
turns, right grade of
correctly assembled
core material, where
bias current is
greater than LPB test
can handle.
ZBX*
Impedance with
External Bias Audio & Telecom Selected Windings Checks impedance at
a given frequency,
while applying a
greater bias current
than is possible with
ZB test.
These tests require the use of one or more Voltech
DC1000 Precision DC Bias Current Sources.
