[SENSe]
[SENSe:]FUNCtion:HVOLtage
[SENSe:]FUNCtion:HVOLtage [<range>,](@<ch_list>) links the specified
VT1529B channels to return dc voltage on the high-level input (Excitation Sense +
and -) pins on the RJ-45 connector for the channel.
This command is valid only on the VT1529B and is available with VXIplug&play
driver revision A.01.09 or later (revision A.01.06 or later of hpe1422_32.dll).
Parameters
Comments •
The VT1422A has five ranges: 0.0625 V dc, 0.25 V dc, 1 V dc, 4 V dc, and
16 V dc. To select a range, simply specify the range value (for example, 4 selects
the 4 V dc range). If a value is specified that is larger than one of the first four
ranges, the VT1422A selects the next higher range (for example, 4.1 selects the
16 V dc range). Specifying a value larger than 16 causes an error. Specifying 0
selects the lowest range (0.0625 V dc). Specifying AUTO selects auto range.
The default range (no range parameter specified) is auto range.
•
The VT1529A/B has a fixed gain of 32. Keep this in mind when <range> is set.
