Boonton 4500B RF Peak Power Analyzer
Remote Operation 5-72
SENSe:IMPedance
Description: Set or return trigger channel impedance for the selected channel. In addition to changing the
trigger channel input impedance, this can be used to calculate and display power from a voltage
measurement..
Syntax: SENSe[3|4]:IMPedance
Argument: = {1, 50} ( 1 Megohm or 50 ohms )
Valid Modes: External trigger inputs only
SENSe:NORMalize
Description: Set or return the state of distribution function normalization. When OFF, measured power (or
voltage) is absolute; when ON, marker power (or voltage) is relative to CDF average power (or
voltage). Marker units are dBr or percent. Affects CH1, CH2, MEM1 and MEM2.
Syntax: SENSe:NORMalize
Argument: = {ON, OFF}
Valid Modes: Statistical
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 level‖ 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|3|4|6|7]:PULSe:DISTal
Argument: = 20.00 to 99.00 percent
Valid Modes: Pulse mode only
SENSe:PULSe:ENDGT
Description: Set or return the point on a pulse, which is used to define the end of the pulse‘s ―active‖ interval.
This point is defined in percent of the total pulse duration, with 0% corresponding to the midpoint
of the rising edge, and 100% corresponding to the midpoint of the falling edge, as defined by the
mesial setting. For most pulse ―on‖ average power measurements, it is desirable to exclude the
rising and falling intervals, and only measure power over the active portion of the pulse. This is
often known as time gating, and is used for the automatic pulse measurements returned by
READ:ARRay:AMEASure:POWer.
Syntax: SENSe[1|2|3|4|6|7]:PULSe:ENDGT
Argument: = 60.00 to 100.00 percent
Valid Modes: Pulse mode only
