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
