4530 Series RF Power Meter
Remote Operation
FETCh:ARRay:MARKer:POWer
Description:
Returns the current power readings at both markers on the specified channel.
Syntax:
FETCh[1
|
2]:ARRay:MARKer:POWer?
Returns:
Pwr@Marker1, Pwr@Marker2 in active units
Valid Modes:
Pulse and Statistical modes
Restrictions:
MARKer:MODe
must be set to
VERT
FETCh:ARRay:MARKer:PERcent
Description:
Returns the current statistical percent readings at both markers on the specified channel.
Syntax:
FETCh[1|2]:ARRay:MARKer:PERcent?
Returns:
Percent@Marker1, Percent@Marker2
Valid Modes:
Statistical mode only
Restrictions:
MARKer:MODe
must be set to
HORZ
FETCh:ARRay:CW:POWer
Description:
Returns the current average, maximum, minimum powers and peak-to-average ratio in dB
(peak sensor) or pulse power (CW sensor) of the specified channel. Note that the values for
maximum and minimum power will depend on the peak hold mode; see the description of the
CALCulate:PKHLD
command for details. If a CW sensor is used, the pulse power returned
is computed from the measured average power and the preset duty cycle (see
CALCulate:DCYC
command). Channel’s units setting is forced to power units.
Syntax:
FETCh[1|2]:ARRay:CW:POWer?
Returns:
Pavg, Pmax, Pmin, PkToAvgRatio (Modulated mode) or Ppulse (CW mode)
Valid Modes:
CW and Modulated modes
FETCh:ARRay:CW:VOLTage
Description:
Returns the current average, maximum, minimum voltage and peak-to-average ratio in dB
(peak sensor) or pulse voltage (CW sensor) for the specified channel. Note that the values
for maximum and minimum voltage will depend on the peak hold mode; see the description
of the
CALCulate:PKHLD
command for details. If a CW sensor is used, min and max
powers returned are always the highest and lowest filtered average readings that have
occurred since the start of the measurement, and the pulse voltage returned is computed
from the measured average power and the preset duty cycle (see
CALCulate:DCYC
com-
mand). Note the peak-to-average ratio is returned in dB for log units, and percent for linear
units. Channel’s units setting is forced to voltage units.
Syntax:
FETCh[1|2]:ARRay:CW:VOLTage?
Returns:
Vavg, Vmax, Vmin, PkToAvgRatio (Modulated mode) or Vpulse (CW mode)
Valid Modes:
CW and Modulated modes
