[SENSe[1]]|SENSe2:CORRection:DCYCle|GAIN3[:INPut]
[:MAGNitude] <numeric_value>
This command is used to set the duty cycle for the pulse power measurement
feature of the power meter. Pulse power measurements average out any
deviations in the pulse, such as, overshoot or ringing. The result returned for a
pulse power measurement is a mathematical representation of the pulse power
rather than an actual measurement. The power meter measures the average
power in the pulsed input signal and then divides the result by the duty cycle
value to obtain a pulse power reading.
Entering a value using this command automatically turns the
[SENSe[1]]|SENSe2:CORRection:DCYCle|GAIN3:STATe command to ON.
Pulse measurements are not recommended using E-Series power sensors at
NOTE
power levels above –20 dBm.
Pulse power averages out any deviations in the pulse such as overshoot or
ringing. Hence, it is called pulse power and not peak power or peak pulse power.
In order to ensure accurate pulse power readings, the input signal must be
pulsed with a rectangular pulse. Other pulse shapes (such as triangle, chirp or
Gaussian) cause incorrect results.
The pulse power on/off ratio must be much greater than the duty cycle ratio.
