Hi, my name is Kah Meng Chew . I'm an engineer at Agilent Technologies,
and today, I'm going to introduce the new multipulse analysis software for the 8990B peak power analyzer.
The multi-pulse software is used to analyze the stability of a radar transmitter or other generic high power amplifier.
The new 8990B multipulse software is designed to,
first, capture and analyze continuously 512 RF pulses for both RF channels,
second, compare any two pulses from the pulse trains,
and third, display histogram distribution presentation for pulse parameters.
These features are especially important for output stability tests.
Now I'm going to demonstrate how the multi-pulse software captures pulse trains and analyze each pulse continuously.
My set up today is very simple and includes only the 8990B peak power analyzer and an Agilent ESG signal source generator.
The N1923A power sensor is connected to the ESG output.
and the ESG has been programmed to continuously transmit pulse bursts, each consisting of 20 individual pulses.
Here, we have captured the burst pulse train on the 8990B screen.
By changing the timescale, we can now zoom into a burst pulse cluster, where you can see the 20 pulses.
Now, we want to analyze each individual pulse in this cluster, so we'll zoom in further to look at the first pulse.
To go into multipulse mode, go to "acquisition", select "multipulse", and the multipulse setup window will appear.
Because we've selected 20 pulses for this demo, enter "20" into for the Frame, then click Acquire.
Once the Frame Acquisition is completed, you can now do a playback to view all the individual pulses.
At the same time, we can also perform multipulse measurements on each pulse, such as Peak, Peak to Average, or Pulse Width.

which will display the numeric measurement of a specific pulse, which in this case, pulse 20.
You can also view the histogram distribution of the respective pulse parameters.
The 8990B can also make pulse-to-pulse comparisons.
For example, for Peak measurement, I am comparing the last pulse to the first pulse.
The results will be shown here.
For peak measurements, this will also represent the droop of the pulse train or cluster.
As I've just demonstrated, the 8990B peak power analyzer is able to capture and continuously analyze pulses
as well as compare any two pulses from a pulse train.
The 8990B is the only peak power analyzer that allows users to easily analyze the stability of high power amplifiers using the multi-pulse feature.
