agb1500_forceCmuDcBias

agb1500_forceCmuDcBias
This function forces DC voltage from the MFCMU or the SMU connected to the
Force1/Sense1 terminals of the SCUU (SMU CMU unify unit).
If you want to apply DC voltage over ±25 V, the SCUU must be connected correctly.
The SCUU can be used with the MFCMU and two SMUs (MPSMU or HRSMU).
The SCUU cannot be used if the HPSMU is connected to the SCUU or if the
number of SMUs connected to the SCUU is only one.
ViStatus _VI_FUNC agb1500_forceCmuDcBias(ViSession vi, ViInt32 channel,
ViReal64 value);
vi Instrument handle returned from agb1500_init( ).
channel Slot number of the slot that installs the MFCMU to be used. See
Table 2-2. channel=-1 detects the slot automatically.
value DC voltage (in V). Numeric expression.
0 (initial setting) to ±100 V
With the SCUU, the source module is automatically selected by
the setting value. The MFCMU is used if voltage is below
±25 V (setting resolution: 0.001 V), or the SMU is used if
voltage is greater than ±25 V (setting resolution: 0.005 V).
The SMU will operate with the 100 V limited auto ranging and
20 mA compliance settings.
If the output voltage is greater than ±42 V, the interlock circuit
must be shorted.

agb1500_init

This function initializes the software connection to the instrument and optionally
verifies that instrument is in the system. In addition, it may perform any necessary
actions to place the instrument in its reset state.
If the agb1500_init function encounters an error, then the value of the vi output
parameter will be VI_NULL.
ViStatus _VI_FUNC agb1500_init(ViRsrc InstrDesc, ViBoolean id_query,
ViBoolean do_reset, ViPSession vi);
