Instrument Specific Commands - TTI QL Serie Manual De Instrucciones

Each query produces a specific
remote commands list.
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
<WHITE SPACE>
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>
<nrf>
<nr1>
<nr2>
The commands which begin with a
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 is completed when the parameter being
adjusted reaches the required value to within ±5% or ±10 counts, whichever is the greater. If the
value fails to settle within these limits within 5 seconds then the Verify Timeout bit (bit 3) is set in the
Standard Event Status Register and the operation is completed at the end of the timeout period.
The Operation Complete bit (bit 0) in the Standard Event Status Register is only ever set by the
*OPC command. The *OPC (or the *OPC?) command can be used for device synchronisation due
to the sequential nature of remote operations.

<RESPONSE MESSAGE>
<RESPONSE MESSAGE TERMINATOR>
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.
A number with no fractional part, i.e. an integer.
A number in fixed point format e.g. 11·52, 0·78 etc.

are those specified by IEEE Std. 488.2 as Common commands.
set the output to <nrf> Volts
set the output to <nrf> Volts with verify
set the output over voltage protection trip point to <nrf> Volts
set the output current limit to <nrf> Amps
set the output over current protection trip point to <nrf> Amps
return the set voltage – response is V1 <nr2><rmt> where <nr2> is in Volts
return the set current limit – response is I1 <nr2><rmt> where <nr2> is in Amps
return the voltage trip setting – response is VP1 <nr2><rmt> where <nr2> is in Volts
return the current trip setting – response is IP1 <nr2><rmt> where <nr2> is in Amps
return the output readback voltage – response is <nr2>V<rmt> where <nr2> is in Volts
