9-32 Remote Operation
DOUT? Query Digital Output Parameters
Input: DOUT?
Returned: <mode>, <bit weighting>. Format: n,nnn[term]
Remarks: Returns the digital output parameters. See the DOUT command for parameter descriptions.
FILTER Configure Input Filter Parameters
Input: FILTER <input>, [<off/on >], [<points>], [<window>]
Returned: Nothing
Remarks: Configures input filtering function.
<input> Specifies input to configure.
<off/on> Specifies whether the filter function is off or on.
<points> Specifies how many data points the filtering function uses.
<window> Specifies what percent of full scale reading limits the filtering function. Reading
changes greater than this percentage reset the filter.
Example: FILTER B, 10, 2[term] - Filter input B data through 10 readings with 2% of full scale window.
FILTER? Query Input Filter Parameters
Input: FILTER? <input>
Returned: <off/on >, <points>, <window>. Format: a,nn,nn[term]
Remarks: Returns input filter configuration. See the FILTER command for parameter descriptions.
<input> specifies which input to query.
HTR? Query Heater Output
Input: HTR?
Returned: <heater value>. Format: nnn.n[term]
Remarks: Returns the heater output in percent.
HTRST? Query Heater Status
Input: HTRST?
Returned: <error code>. Format: nn[term]
Remarks: Returns the heater error code (Paragraph 11.8).
IEEE Configure IEEE-488 Interface Parameters
Input: IEEE [<terminator>], [<EOI enable>], [<address>]
Returned: Nothing
Remarks: Configures parameters of the IEEE interface.
<terminator> Specifies the terminator. Valid entries: 0 = no terminator, 1 = <CR><LF>,
2 = <LF><CR>, 3 = <CR>, 4 = <LF>.
<EOI enable> Disables/enables the EOI mode.
<address> Specifies the IEEE address.
Example: IEEE 1, 1, 4[term] - After receipt of the current terminator, the instrument responds to
address 4, uses <CR><LF> as the new terminator and uses EOI mode.
IEEE? Query IEEE-488 Interface Parameters
Input: IEEE?
Returned: <terminator>, <EOI enable>, <address>. Format: n,n,nn[term]
Remarks: Returns the IEEE interface parameters. See the IEEE command for parameter descriptions.
