5.5 QUERY FUNCTIONS
The following are 'query only' functions sent to the UPC through the communication bus.
5.5.1 CONFIGURATION QUERIES
These query parameters cannot be set via the remote communication port. The values of each are
specific to the hardware configuration of the individual power source.
:[SOURce]:XFMRRATIO? Query: Output XFMR ratio.
Returns <0.05> to <5.00>. See 3.7.1 and 4.6.3.3
:[SOURce]:AVR? Query: Current transformer AMPS:VOLTS ratio.
Returns <1> to <500>. See 3.7.2 and 4.6.3.3
:[SOURce]:CTLOC? Query: Current transformer location.
Returns <1> (PRIMARY) or <0> (SECONDARY). See 4.6.3.7
:[SOURce]:AMPLIFIERS? Query: Number of installed power amplifiers in Power Source.
See 4.6.3.3
:SENSe:CURRent:RANGe? Query: AMPS meter range.
Returns <0> to <AMPS meter range> RMS Amps
5.5.2 METERED DATA QUERIES
Measurement occurs once per :MEASure: command. AC measurements are assumed.
•
The SCPI :AC keyword following :MEASure is optional and is not shown here.
•
The “ ? ” is optional, :MEASure: implies a query. Values following a command are ignored
•
'Multiple keyword' queries may be performed to obtain values of simultaneous measurements.
e.g., :MEASure:VOLTage1;VOLTage2;VOLTage3?
:MEASure:VOLTage1? Query: metered voltage
Φ
A.
Returns <0> to <354> VAC RMS
:MEASure:VOLTage2? Query: metered voltage Φ B.
Returns <0> to <354> VAC RMS
:MEASure:VOLTage3? Query: metered voltage Φ C.
Returns <0> to <354> VAC RMS
:MEASure:VLL1? Query: metered Line to Line voltage Φ A - Φ B.
Returns <0> to <354> VAC RMS
:MEASure:VLL2? Query: metered Line to Line voltage
Φ
B -
Φ
C.
Returns <0> to <354> VAC RMS
:MEASure:VLL3? Query: metered Line to Line voltage Φ C - Φ A.
Returns <0> to <354> VAC RMS
