4-80 Agilent B1500A/B1505A Programming Guide, Edition 11
Command Reference
ERHPA
value : Decimal value of the output status bit pattern. Integer expression. 0 to
65535. The bit pattern must comply with the following rule:
Bit value 0: TTL high level (approx. 2.4 V)
Bit value 1: TTL low level (approx. 0.8 V)
rule : Place holder to keep the same syntax as the ERC command of the
Agilent 4142B. Input value is ignored.
Example
Statements
If you want to set TTL low level for the output ports of the digital I/O port bit 0 to 7,
enter the following command.
OUTPUT @B1500;"ERC 2,255"
where the decimal value 255 means binary bit pattern 0000000011111111. This
command does not change the status of the trigger ports and the input ports.

ERMOD 2 command.
Syntax ERHPA hvsmu,hcsmu,hpsmu
Parameters hvsmu : Channel number of HVSMU connected to the HVSMU port directly or
via the N1266A expander.
hcsmu : Channel number of HCSMU or DHCSMU connected to the HCSMU
port
smu : Channel number of MPSMU or HPSMU connected to the HPSMU port
Effective channel numbers are 1 to 10, or 101 to 1001. Integer expression. See Table
4-1 on page 4-16.
Enter 0 if the associated module is not installed.
