IQ-3100/3300 allow you to create automatic programs such as an
automatic attenuation scan of up to 100 steps with a dwell time up to 1000
hours per step by clicking on

The IQ-3100 and IQ-3300 program principle is illustrated by two sample
programs in the table below. The sample programs contain three steps.
Referring to the sample programs shown above, in the case of the IQ-3100,
the incoming signal is first attenuated by 2.500 dB for 10 seconds, then by
5.000 dB for 1 minute, and finally by 4.000.dB for 1 hour.
In the case of the IQ-3300, 20.000 dB is first reflected off the original signal
for 10 seconds, then 30.000 dB off the original signal for 1 minute, and
finally 40.000 dB off the original signal for 1 hour.
