Min – ( the maximum frequency of the instrument). (that is, a 27 GHz max freq instrument has a CF step
range of +/– 27 GHz)
Max The maximum frequency of the instrument. (that is, a 27 GHz max freq instrument has a CF step
range of +/– 27 GHz)

Initial S/W Revision A.07.00
Freq à Signal (Replace)
Replaces the frequency of the selected signal with the set Frequency. Trace, Disturbance level (E meas),
Probability of Time (ρ meas) and Delta To Limit values will be shown as “--“ to indicate that those values
are undefined. TimeStamp will be updated. Signal list will be re-sorted based on the auto sort setting.

Notes If the signal list contains no data, an error is generated and this function cannot be performed.
If the selected signal is not in the list, an error is generated and this function cannot be performed.
Initial S/W Revision A.13.00
Freq à List (Append)
Append the set Frequency to the signal list. Trace, Disturbance level (E meas), Probability of Time (ρ meas)
and Delta To Limit values will be shown as “--“to indicate that those values are undefined.
