Command Reference
PCH?
Syntax PCH master,slave
Parameters master : Channel number of HCSMU used as the dual HCSMU master channel
slave : Channel number of HCSMU used as the dual HCSMU slave channel
Integer expression. 1 to 10 or 101 to 1001. See Table 4-1 on page 4-16.

ENTER @B1500;Master,Slave
PCH?
PCH?, PCH? 0, and PCH? master commands return the master HCSMU channel
number and the slave HCSMU channel number used for the dual HCSMU.
This command returns 0 if the dual HCSMU (DHCSMU) is not specified by master.
Syntax PCH? [master]
Parameters master : Master HCSMU channel number. Integer expression. 1 to 10 or 101 to
1001. See Table 4-1 on page 4-16.
Query Response master,slave<CR/LF^EOI>
master: Master HCSMU channel number
slave: Slave HCSMU channel number
PDCV
This command sets the pulsed voltage source used for the pulsed spot C
measurement (MM19). The source will be the MFCMU, or the SMU that can be
connected to the Force1/Sense1 terminals of the SCUU (SMU CMU unify unit).
Execution
Conditions
The CN/CNX command has been executed for the specified channel.
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.
If the output voltage is greater than the allowable voltage for the interlock open
condition, the interlock circuit must be shorted.
