Boonton 4540 Series RF Power Meter
Remote Operation
5-55
SENSe:FILTer:STATe
Description:
Set or return the current setting of the integration filter on the selected channel. OFF provides no
filtering, and can be used at high signal levels when absolute minimum settling time is required.
ON allows a user-specified integration time, from 2 milliseconds to 15 seconds (see
SENSe:FILTer:TIMe
command). Note that setting the filter time will force the state to ON.
AUTO uses a variable amount of filtering, which is set automatically by the power meter based on
the current signal level to a value that gives a good compromise between measurement noise and
settling time at most levels.
Syntax:
SENSe[1|2]:FILTer:STATe <character data>
Argument:
<character data> = {OFF, ON, AUTO}
Valid Modes:
Modulated
SENSe:FILTer:TIMe
Description:
Set or return the current length of the integration filter on the selected channel. If the filter state is
set to AUTO, querying the time will return -0.01, and if set to OFF, a time query will return 0.00.
Note that setting the filter time will force the state to ON.
Syntax:
SENSe[1|2]:FILTer:TIMe <numeric_value>
Argument:
<numeric_value> = 0.002 to 16.000 seconds in 2 millisecond increments
Valid Modes:
Modulated
SENSe:IMPedance
Description:
Set or return the current impedance reference in ohms for voltage to power conversions when
using a voltage probe sensor.
Syntax:
SENSe[1|2]:IMPedance <numeric_value>
Argument:
<numeric_value> = 10.0 to 2500.0 ohms
Valid Modes:
Voltage Probe (Modulated)
SENSe:PULSe:DISTal
Description:
Set or return the pulse amplitude percentage, which is used to define the end of a rising edge or
beginning of a falling edge transition. Typically, this is 90% voltage or 81% power relative to the
―top lev
el‖
of the pulse. This setting is used when making automatic pulse risetime and falltime
calculations returned by READ
:ARRay:AMEASure:POWer.
Syntax:
SENSe[1|2]:PULSe:DISTal <numeric_value>
Argument:
<numeric_value> = 50.00 to 100.00 percent
Valid Modes:
Pulse Mode only
