Remote Operation 5-57
SENSe:PULSe:STARTGT
Description:
Set or return the point on a pulse, which is used to define the beginning 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 FETCh:ARRay:AMEASure:POWer.
Syntax: SENSe[1|2]:PULSe:STARTGT <numeric_value>
Argument: <numeric_value> = 0.00 to 40.00 percent
Valid Modes: Pulse Mode only
SENSe:PULSe:UNIT
Description: Set or return the units for entering the pulse distal, mesial and proximal levels. If the function is
set to VOLTS, the pulse transition levels will be defined as the specified percentage in voltage. If
set to WATTS, the levels are defined in percent power. Many pulse measurements call for 10% to
90% voltage (which equates to 1% to 81% power) for risetime and falltime measurements, and
measure pulse widths from the half-power (–3dB, 50% power, or 71% voltage) points.
Syntax: SENSe[1|2]:PULSe:UNIT <character data>
Argument: <character data> = {WATTS, VOLTS}
Valid Modes: Pulse Mode only
SENSe:SENSOR:TYPE?
Description: Returns the sensor type for the selected channel.
Syntax: SENSe[1|2]:SENSOR:TYPE?
Returns: <character data> = { NONE, CW, VOLT, PEAK }
Valid Modes: All
