Measurement Item Symptoms of Problem To Guess the Cause of Problem
Auto Configuration “Auto Configuration
Error” occurs or TAA
measurement data
and/or PW
measurement data is
unacceptable.
If a parameter of write and sense
current data is unsuitable, it is
assumed that the head amplifier,
E5035B or E5038B has some
problem.
Read/Write Offset
Measurement
“No Peak” error
message occurs during
the measurement or
track profile data is
unacceptable.
It is assumed that the instrument
except for the Oscilloscope,
E5039B/C, and E5038B gives
problem. Firstly, check and replace
the E5037C/D, Head Amp, E5035B
and E5040A in sequence. Still, if you
can not isolate a defective instrument,
refer to “Troubleshooting” chapter of
spinstand service manual.

Module
TAA is unacceptable in
spite of the PW and
Baseline measurement
data are acceptable.
Check the SMA - SMA cable
connecting ‘Fltrd Out 3’ connector on
the E5036A and ‘Signal In’ connector
on the E5038B. If cable connection is
good, replace the E5038B. (The
E5038B consists of three separated
measurement part as TAA
measurement part, PW measurement
part and Baseline measurement part.)
PW is unacceptable in
spite of the TAA and
Baseline are acceptable.
Baseline is
unacceptable in spite of
the TAA and PW are
acceptable.
Parametric
measurement data is
unacceptable in spite of
the Narrow band TAA
measurement data
measured by the
E5040A is acceptable.
Narrow Band TAA
Measurement
Narrow Band TAA is
unacceptable which is
measured by the
E5040A, but TAA is
acceptable which is
measured by the
E5038B.
Check the SMA - SMA cable
connecting ‘Thru Out 1’ on the
E5036A and ‘Signal In’ on the
E5040A. In addition, check the
SMA-BNC cable connecting ‘Ref
Out’ connector on the E5037C/D and
‘Ext Ref In’ connector on the
E5040A. If the cable connections are
good, replace the E5040A.
