Multi Channel Spot Measurement
Multi Channel Spot Measurement
Table 3-3 explains example subprograms that enable/disable measurement channels
(perform_meas), perform the multi channel spot measurement (mspot_meas), and
display measurement result data (display_data). This example measures bipolar
transistor collector current and base current.
Table 3-3 Multi Channel Spot Measurement Example
Sub perform_meas(vi As Long, ret As Long) ’1
Dim pins(3) As Long ’SMU port numbers ’3
pins(0) = 1 ’SMU1: emitter
pins(1) = 2 ’SMU2: base
pins(2) = 4 ’SMU4: collector
ret = agb1500_setSwitch(vi, pins(2), 1) ’8
ret = agb1500_setSwitch(vi, pins(1), 1)
ret = agb1500_setSwitch(vi, pins(0), 1)
check_err vi, ret ’11
mspot_meas vi, ret, pins() ’13
ret = agb1500_setSwitch(vi, agb1500_CH_ALL, 0) ’15
check_err vi, ret
End Sub ’18
Line Description
1 Beginning of the perform_meas subprogram.
3 to 6 Declares variables, and defines the value.
8 to 10 Enables measurement channels.
13 Calls the mspot_meas subprogram (next page) to perform multi
channel spot measurement.
15 Disables measurement channels.
11 and 16 Calls the check_err subprogram (shown in Table 3-1) to check if
an error status is returned for the previous line.
18 End of the perform_meas subprogram.
