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.

command for parameter descriptions.
<input>
specifies which input to query.
HTR?
Query
Heater
Output
Input: HTR?

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.
