5.5.2 METERED DATA QUERIES (cont)
:MEASure:PF1?
Query: metered power factor (KW/KVA)
Φ
A.
Returns <0> to <1.0>
:MEASure:PF2?
Query: metered power factor (KW/KVA)
Φ
B.
Returns <0> to <1.0>
:MEASure:PF3?
Query: metered power factor (KW/KVA)
Φ
C
.
Returns <0> to <1.0>
:FETCh[:WAVEform]:VOLT1?
:FETCh[:WAVEform]:CURRent1?
Query: metered waveform data (line-to-neutral voltage only).
Use
:VOLT1
for
Φ
A,
:VOLT2
for
Φ
B, and
:VOLT3
for
Φ
C
volts
Use
:CURR1
for
Φ
A,
:CURR2
for
Φ
B, and
:CURR3
for
Φ
C
current
Returns a string of NR2 type numbers, comma delimited. Only a
single waveform may be queried in a command.
:MEASure:SPECTrum:VOLT1[:MAGnitude]?
(option: Harmonic Analysis and Synthesis)
[:ABSolute]?
:MEASure:SPECTrum:CURRent1[:MAGnitude]?
[ABSolute]?
Query: waveform harmonic magnitudes
Use
:VOLT1
for
Φ
A,
:VOLT2
for
Φ
B, and
:VOLT3
for
Φ
C
volts
Use
:CURR1
for
Φ
A,
:CURR2
for
Φ
B, and
:CURR3
for
Φ
C
current
Returns a data set of 51, NR2 type numbers, comma delimited. The
1
st
element is the magnitude of the fundamental, for reference. The 2
nd
element is the 2
nd
harmonic, etc. The accuracy of harmonics may be
limited by the FREQUENCY SPAN setting.
See para. 4.3.1.1 and 5.4.1.
:MAG
returns each magnitude as a percent of the fundamental.
:
ABS
returns absolute magnitude
:MEASure:SPECTrum:PHASe?
(option: Harmonic Analysis and Synthesis)
Query: phase angles in degrees for the most recent harmonics data
Returns a data set of 51, NR2 type numbers, comma delimited. The
1
st
element is the angle of the fundamental, for reference. The 2
nd
element is the angle of the 2
nd
harmonic, etc. The previous
:MEASure:SPECTrum:parameter
command defines which phase
angles are sent. If parameter was VOLT1 then the phase angles will
be for VOLT1.
:MEASure:SPECTrum:THD?
(option: Harmonic Analysis and Synthesis)
Query: Returns Total Harmonic Distortion of the most recent
:MEASure:SPECTrum:parameter
command, as above.
:MEASure:SPECTrum:OHD?
(option: Harmonic Analysis and Synthesis)
Query: Returns Odd Harmonic Distortion of the most recent
:MEASure:SPECTrum:parameter
command, as above.
:MEASure:SPECTrum:EHD?
(option: Harmonic Analysis and Synthesis)
Query: Returns Even Harmonic Distortion of the most recent
:MEASure:SPECTrum:parameter
command, as above.
