READ?
The MEASure:SCALar queries set up the Digital Input for a single measure-
ment, reads a value, and returns the requested data.
The MEASure:ARRay queries set up the Digital Input for multiple reads, reads
the values, and returns the requested data.
The voltage threshold can be specified or set to default. For ARRay: queries, the
sample rate is set to default. When a NORMal query is used, data is returned as a
1 of the input is higher than the input threshold and a 0 if the input is lower than
the threshold. For an INVerted query, the opposite is true. The data mode will be
formatted, i.e. all disabled bits will be returned as 0.
If a port list is used, selected ports will be enabled or disabled. Only bits enabled
as input ports can be queried for input. The port list can be comma separated or
listed as (x:y) for ports x through y.
Data is returned in the following format:
<data>{,<data>}
