Boonton 4540 Series RF Power Meter
Operation 4-27
4.5.15 Channel > Extensions Pg 1 > Define Pulse Menu (Pulse Mode)
The define pulse menu contains items for adjusting how automatic pulse measurements are calculated. Measurements such
as rise time, fall time, and pulse width are affected by these adjustments. For more information on pulse calculation
definitions, see section 6.2 Pulse Definitions. This menu is only valid for peak power sensors in pulse mode.
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Define Pulse > Distal
Description: Set 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.
Menu Type: Numeric value.
Range: 50.00 % to 99.00 %
SCPI Command: SENSe[1|2]:PULSe:DISTal
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Define Pulse > Mesial
Description: Set the pulse amplitude percentage, which is used to
define the midpoint of a rising or falling edge transition.
Typically, this is 50% voltage or 25% power relative to
the ―top level‖ of the pulse. This setting is used when
making automatic pulse width and duty cycle
calculations.
Menu Type: Numeric value.
Range: 10.00 % to 90.00 %
SCPI Command: SENSe[1|2]:PULSe:MESIal
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Define Pulse > Proximal
Description: Set or return the pulse amplitude percentage, which is used to define the beginning of a
rising edge or end of a falling edge transition. Typically, this is 10% voltage or 1%
power relative to the ―top level‖ of the pulse. This setting is used when making
automatic pulse rise time and fall time.
Menu Type: Numeric value
Range: 0.00 % to 50.00 %
SCPI Command: SENSe[1|2]:PULSe:PROXimal
