Command List

This section lists all commands and queries implemented in this instrument.
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 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.
<n> The number of the output (1, 2, etc) or associated status register to which the
command relates. For this single output instrument <n> is always '1', so the
commands are, for example, V1 <nrf>, I10?, etc. This is to keep the command
format entirely compatible with that used on multi-output TTi programmable power
supplies; a dual output supply, for example, would have a duplicate set of
commands V2<nrf>, I20?, etc.
The commands which begin with a
commands. All will function when used on the other interfaces but some may be 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.
