See “Using EasyEXPERT” on page 4-1 for the functions available for Agilent
EasyEXPERT software. See Programming
Guide for the functions available for the
GPIB remote mode. See Agilent B1530A User’s Guide for using the WGFMU.
GNDU - Ground Unit
Agilent B1500A is equipped with the ground unit (GNDU). The GNDU is a 0 V
constant voltage source, and used for the reference of measurement ground. Also the
GNDU can sink up to ± 4.2 A, so it is effective for using the HPSMU (high power
SMU). Figure 2-1 is a simplified circuit diagram of GNDU.
