****************************
Please read this manual when you obtain the programme.
---Based on Labview platform of VI Inc.---
Programme entry for each measurement module/function is following.
1) Wideband magnetoelectric(ME) measurement system,
3D mapping of ME coupling amplitudes and phases
versus frequency and bias magnetic field:
./general/ME main panel.vi
2) Precision impedance spectrum and magnetoimpedance
spectrum sweeping system. 3D mapping is also available:
./general/impedance/ME main panel.vi
3) Precision ac I-V measurement with frequency sweeping:
./general/I-V characterization/precision I-V f scanning.vi

Description for sub folders:
1) ./BC_AD-DA card, basic communication interface
of AD/DA converter. Here the instances was
implemented for AC6632 and AC6682 cards produced by
Baotron Inc. P.R. China (www.baotron.com).
2) ./General, main control for application programmes
without interface for any hardware.
3) ./lock-in, totally virtual high-performance lock-in
amplifers, which is essential innovation of
our precision-guaranteed measurement system,
implying you don't need to prepare any commercial
lock-ins as soon as you have a digital oscilloscope.
