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 <n>
Argument:
<n> = 0 to 40 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
FETCh:ARRay:AMEASure:POWer.
Syntax:
SENSe[1|2]:PULSe:ENDGT <n>
Argument:
<n> = 60 to 100 percent
Valid Modes:
Pulse mode only
SENSe:TEMPerature
Description:
Return the current internal temperature of the selected peak power sensor. This tempera-
ture may be compared to the autocal temperature (see
SENSe:CALTemp?
) to aid in decid-
ing whether the sensor temperature has drifted enough to warrant a new autocal. The 4530
displays a warning message on the LCD if a non-temperature compensated peak sensor is
in use, and the temperature has drifted more than 4C from the autocal temperature.
Syntax:
SENSe[1|2]:TEMPerature?
Returns:
SensorTemp in degrees C
Valid Modes:
Peak Sensors only
SENSe:CALTemp
Description:
Return the internal peak power sensor temperature at the time of autocalibration. This
temperature may be compared to the current sensor temperature (see SENSe:TEMPerature?)
to aid in deciding whether the sensor temperature has drifted enough to warrant a new
autocal. The 4530 displays a warning message on the LCD if a non-temperature compen-
sated peak sensor is in use, and the temperature has drifted more than 4C from the autocal
temperature.
Syntax:
SENSe[1|2]:CALTemp?
Returns:
AutocalTemp in degrees C
Valid Modes:
Peak Sensors only
