Agilent B1500A/B1505A Programming Guide, Edition 11 4-149
Command Reference
PCH
1 to 16: Port 1 to 16 of the digital I/O terminal.
To use a digital I/O port, send the TGP command. The port value must
be same as the port value set to the TGP command.
wait time : -99.9999 to 99.9999 seconds, with 100 μsec resolution. Numeric
expression.
If wait time is not specified or negative wait time is set, the paused
status is kept until receiving an event specified by the TM command.
Remarks The TM3 command enables an external trigger from a trigger input terminal
specified by the port parameter as an event used to break the pause state set by the
PA command.
The B1500 counts the wait time independent of the source wait time and the
measurement wait time set by the WAT command. So the wait time can cover them
as shown in the following program example:
OUTPUT @B1500;"CN";1
OUTPUT @B1500;"WAT";1,0,1E-3 !Source Wait Time =1ms
OUTPUT @B1500;"WAT";2,0,1E-3 !Meas Wait Time =1ms
OUTPUT @B1500;"DV";1,0,5,1E-2
OUTPUT @B1500;"PAX";-1,1E-3 !Wait Time =1ms
OUTPUT @B1500;"TI";1
ENTER @B1500 USING "#,3X,13D,X";Idata
Example
Statements
OUTPUT @B1500;"PAX 1,10"

PCH
This command specifies two HCSMU modules and enables the dual HCSMU
operation. The HCSMU modules of channel numbers master and slave operate as
the dual HCSMU (DHCSMU) of channel number master, and do not perform the
single HCSMU operation.
This setting is cleared by the PCH 0,0, PCH master,0, *RST, or a device clear (HP
BASIC CLEAR) command.
Execution
Conditions
Two HCSMU modules are installed in the B1505A and connected to the
16493S-020 Dual HCSMU Kelvin combination adapter or the 16493S-021 Dual
HCSMU combination adapter.
The CN/CNX command has not been executed for the specified channels.
