Figure 13. Wideband pulse profile data acquisition using widest IF bandwidth
In wideband pulse profile measurements, all the data is acquired with a single
pulse, thus the pulse width needs to be relatively wide (Figure 13). For each
data point with 1 MHz and wider IF bandwidth on DSP version 4 or 10 kHz
and wider IF bandwidth on DSP version 5, the latter half of samples from the
previous data point are used for the first half of samples of the next data point.
This means that the data acquisition timing resolution is one-half of the data
acquisition time. With DSP version 4 widest IF bandwidth of 5 MHz, the last
8 samples of previous data points and 8 new samples are used to calculate a
new data point, which makes 133 ns minimum time resolution measurements.
It becomes 50 ns minimum time resolution with DSP version 5 widest IF
bandwidth of 15 MHz.
