Test Description Transformer Application Reason for Test
ILOS Insertion Loss Audio & telecom
Checks power lost within
the transformer
RESP Frequency Response Audio & telecom
Checks losses over a
range of frequencies
RLOS Return Loss Audio & telecom
Checks power returned
by a transformer
Z Impedance Audio & telecom
Checks impedance at a
given frequency
ZB Impedance with Bias Audio & telecom
Checks impedance at a
given frequency
ANGL Impedance Phase Angle Audio & telecom
Checks phase angle of
complex impedance
PHAS Interwinding Phase Angle Measuring & signal
Checks phase of voltage
between windings
X Reactance Audio & telecom
Checks imaginary part of
the complex impedance
at a given frequency
TRIM Trimming Adjustment
Transformers with variable
/ trimmable components
Adjusts transformer
parameter to desired
value during test
OUT Output to User Port
Performs external
switching as part of the
test program
LSBX*
Inductance with External
Bias (Series Circuit)
Wound components that
usually carry a significant
DC Bias current in normal
operation.
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.
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
Checks impedance at a
given frequency, while
applying a greater bias
current than is possible
with ZB test.
