PLSDIV TIS Commands
PlsdivInit
Auto Adjustment
This function is set by the PlsdivSetAdjustStat command, and is used to adjust the
gate voltage automatically so that the
vg_mon value is close to the vg_high value
specified by the PlsdivSetVgLevel command.
Response Status code. Numeric value. To read the error message, use PlsdivErrorMessage. If
no error is detected by this command execution, 0 is returned.
PlsdivInit
This command initializes the pulsed IV test system. This command must be
executed before any other Plsdiv command.
Filename PlsdivInit.exe
Write Type
String
Read Type
String. However, this command does not return any output parameter.
Write String This command needs the following input parameters in this sequence.
connect_check Connection check status. Numeric value, 0 (does not perform)
or 1 (performs connection check in the PlsdivInit process).
gate_zero Gate zero status. Numeric value, 0 (does not perform) or
1 (performs gate monitor channel offset measurement in the
PlsdivInit process).
Gate Zero This function is used to measure the offset data of the gate voltage monitor path and
update the offset value in a system file. The offset value is used until the next
execution. Before performing the offset measurement, set up the test system
measurement path properly and open the measurement terminals.
Connection Check
This function is used to confirm if the divider, terminator, and bias-T are connected
properly. For the proper connections, see Figure 6-2 and Figure 6-3. The connection
check can detect the following improper connections.
• divider is not connected
• terminator is not connected
• T-adapter is connected instead of divider
• bias-T’s DC+RF connector is connected to the gate monitor channel
