Fluke 6105A - Interharmonics Phenomenon; Dip Phenomenon

6100B/6105A
Users Manual
5-38
This command selects the specified phase’s voltage channel fluctuating harmonics
modulation shape:
• RECT will set the modulation waveform to be rectangular.
• SIN will set the modulation waveform to be sinusoidal.
• SQU will set the modulation waveform to be square.
The query command will return SIN if the modulation shape is sinusoidal etc.
SOURce:PHASe<x>:VOLTage:FHARmonics:DUTY(?) <dnpd>
This command sets the specified phase’s voltage channel fluctuating harmonics duty cycle
value for rectangular modulation.
The query command will return the present duty cycle value. The returned number will be
in standard scientific format (10.55 would be returned as 1.055E1).
5-57. Interharmonics Phenomenon
SOURce:PHASe<x>:VOLTage:IHARmonics:STATe(?) <bool>{OFF|ON|0|1}
This command turns the specified phase’s voltage channel interharmonics phenomena on
and off.
• ON or 1 will enable interharmonics on this phase’s voltage channel.
• OFF or 0 will disable interharmonics on this phase’s voltage channel.
The query command will return 1 if the interharmonics are enabled, or 0 if the inter-
harmonics are disabled.
SOURce:PHASe<x>:VOLTage:IHARmonics:SIGNal<y> <bool>
{OFF|ON|0|1}[,<dnpd>,<dnpd>]
This command sets the specified inter-harmonics parameters. The <bool> parameter
controls whether the inter-harmonic is active or not. The two optional <dnpd> parameters
are numbers, which set the required amplitude (expressed in volts), and the required
frequency (expressed in Hertz). <y> specifies the inter-harmonic to be set since the
instrument is capable of producing 2 inter-harmonics simultaneously.
SOURce:PHASe<x>:VOLTage:IHARmonics:SIGNal<y>? [<cpd>{STATe |
AMPLitude | FREQuency}]
The default version of this query returns all of the settings of the specified Inter Harmonic,
comma separated. Add the appropriate optional parameter to query just one of these values.
5-58. Dip Phenomenon
SOURce:PHASe<x>:VOLTage:DIP:STATe(?) <bool>{OFF|ON|0|1}
This command turns the specified Phase’s Voltage channel Dip phenomena on and off.
• ON or 1 will set the specified Dip to be applied.
• OFF or 0 will set the specified Dip to be removed.
The query command will return 1 if Dip is applied, or 0 if Dip is inactive.
SOURce:PHASe<x>:VOLTage:DIP:ENVelope <dnpd>,<dnpd>,<dnpd>,<dnpd>,<dnpd>
This command sets the specified phase’s voltage channel dip parameters:
• 1
st
dnpd - Change To value (expressed as a percentage of total RMS voltage).
• 2
nd
dnpd - Ramp In period (expressed in Seconds or Cycles).
• 3
rd
dnpd - Duration (expressed in Seconds or Cycles).
• 4
th
dnpd - Ramp Out period (expressed in Seconds or Cycles).
• 5
th
dnpd - End Delay period (expressed in Seconds or Cycles).
