QUERY FUNCTIONS

The following are 'query only' functions sent to the UPC through the communication bus.

5.5.1 CONFIGURATION QUERIES

These query parameters are set via DIP switches within the UPC, not via bus communication. The
values are specific to the hardware configuration of the individual power source.
:[SOURce]:XFMRRATIO?
:[SOURce]:AVR?
:[SOURce]:CTLOC?
:[SOURce]:AMPLIFIERS?
:SENSe:CURRent:RANGe?

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 as :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?
:MEASure:VOLTage2?
:MEASure:VOLTage3?
:MEASure:VLL1?
:MEASure:VLL2?
:MEASure:VLL3?
Query: Output XFMR ratio.
Returns <0.01> to <5.11>. See para. 3.4.1
Query: Current transformer AMPS:VOLTS ratio.
Returns <1> to <511>. See para. 3.4.2
Query: Current transformer location.
Returns <1> (PRIMARY) or <0> (SECONDARY). See para. 3.4.4
Query: Number of installed power amplifiers in Power Source.
See para. 3.4.4
Query: AMPS meter range.
Returns <0> to <AMPS meter range> RMS Amps
Query: metered voltage ΦA.
Returns <0> to <354> VAC RMS
Query: metered voltage ΦB.
Returns <0> to <354> VAC RMS
Query: metered voltage ΦC.
Returns <0> to <354> VAC RMS
Query: metered Line to Line voltage ΦA to ΦB.
Returns <0> to <354> VAC RMS
Query: metered Line to Line voltage ΦB to ΦC.
Returns <0> to <354> VAC RMS
Query: metered Line to Line voltage ΦC to ΦA.
Returns <0> to <354> VAC RMS
