Each query produces a specific
<RESPONSE MESSAGE>
which is listed along with the command in
the remote commands list.
<WHITE SPACE>
is ignored except in command identifiers. e.g. '*C LS' is not equivalent to '*CLS'.
<WHITE SPACE>
is defined as character codes 00H to 20H inclusive with the exception of the NL
character (0AH).
The high bit of all characters is ignored.
The commands are case insensitive.
Command List
This section lists all commands and queries implemented in this instrument. The commands are
listed in alphabetical order within the function groups.
Note that there are no dependent parameters, coupled parameters, overlapping commands,
expression program data elements or compound command program headers; each command is
completely executed before the next command is started. All commands are sequential and the
operation complete message is generated immediately after execution in all cases.
The following nomenclature is used:
<rmt>
<RESPONSE MESSAGE TERMINATOR>
<nrf>
A number in any format. e.g. 12, 12·00, 1·2 e1 and 120 e-1 are all accepted
as the number 12. Any number, when received, is converted to the required
precision consistent with the use then rounded up to obtain the value of the
command.
<nr1>
A number with no fractional part, i.e. an integer.
<nr2>
A number in fixed point format e.g. 11·52, 0·78 etc.
The commands which begin with a
*
are those specified by IEEE Std. 488.2 as Common
commands. All will function when used on the RS232 interface but some are of little use.
Instrument Specific Commands
For commands specified as 'WITH VERIFY' the Operation Complete message is generated when
the parameter being adjusted reaches the required value to /-5% or +/-10 counts,
whichever is the greater. If the value fails to settle to within these limits within 5 seconds then the
Verify Timeout bit (bit 3) is set in the Standard Event Status register and the Operation Complete
message will not be generated.
V1 <nrf>
set the output to <nrf> Volts
V1V <nrf>
set the output to <nrf> Volts with verify
OVP1 <nrf>
set the output over voltage protection trip point to <nrf> Volts
I1 <nrf>
set the output current limit to <nrf> Amps
OCP1 <nrf>
set the output over current protection trip point to <nrf> Amps
V1?
return the set voltage – response is V1 <nr2><rmt> where <nr2> is in Volts
I1?
return the set current limit – response is I1 <nr2><rmt> where <nr2> is in
Amps
OVP1?
return the voltage trip setting – response is VP1 <nr2><rmt> where <nr2> is
in Volts
OCP1?
return the current trip setting – response is IP1 <nr2><rmt> where <nr2> is
in Amps
V1O?
return the output readback voltage – response is <nr2>V<rmt> where <nr2>
is in Volts
