*OPT? - Optional Identification Query
This command does an optional identification query, which means it displays the software version.
Example:
*OPT?
Query of version number
08.06.2012 V42
Unit answers: Version 42 vom 08.06.2012
OVP[,<U
ovp
>] - Over Voltage Protection
This command adjusts the over voltage protection. Entering the command without parameter displays the present set
point. If the set point is higher than a maximum of 1.2 x voltage of the unit, the range error bit within the ESR register
of the interface is set. The present set point remains unchanged.
Example:
GTR
Remote operation mode
OVP,200
Over voltage protection 200 V
UA,100
Output voltage 100 V
IA,10
Output current 10 A
SB,R
Output open
PCx[,<baud>,<parity>,<data bits>,<stop bits>,<handshake>,<echo>,<timeout>] - Program Communication
This command adjusts the interfaces. The LAB/HP/E has a maximum of 3 digital interfaces (x = 1, 2 or 3). The
corresponding commands are
PC1
,
PC2
or
PC3
. Type and number of parameters depend on the type of interface.
Currently there are no settings available for GPIB and LAN. Entering the command without parameter displays present
interface parameters.
Parameter
Function
