Measurement time
The measurement time can be set to Gen Track or a fixed
duration ranging from 0.0078125 s (equivalent to a
measurement rate of 128 readings/s) to 1 s. When the
measurement time is set to Gen Track, the analyzer will vary
the measurement time according to the generator frequency
for the same channel. This is useful when making sweep
measurements as the measurement time will be optimized
for fast sweeps. However, Gen Track works only if the signal
is looped back from the U8903A output to its input.
