Insert Row Below

Inserts a row below the current row. The new row is a copy of the current row and

becomes the current row. The new row is not yet entered into the underlying table,

and the data in the row is displayed in light gray. To enter the row into the table,

press the Enter key, or tap either value then edit it.

Scale X Axis

Matches the X Axis to the selected Limit, as closely as possible.

For frequency limits and a frequency-domain X-axis, sets Start Freq and Stop Freq

to contain the minimum and maximum Frequency of the selected Limit.

–

For linear Frequency Scale, the range between Start Freq and Stop Freq is

12.5% above the range between the minimum and maximum frequency, so that

span exceeds this range by one graticule division on either side (but never set

Start Freq below 0 Hz nor Stop Freq above the maximum instrument frequency)

–

For log Frequency Scale, Start Freq is set to the bottom of the decade in which

the minimum frequency of the Limit appears, and Stop Freq is set to the top of

the decade in which the maximum frequency of the Limit appears. In either case,

if the frequency is at a decade boundary, we take that boundary as being the

bottom/top of the decade in which the frequency appears. Example: Limit goes

from 150kHz to 1GHz, set Start Freq to 100kHz, Stop Freq to 1GHz

For time limits and a time-domain X-axis, sets the sweep time to match the

maximum Time of the selected Limit.

If the domain of the selected limit does not match the domain of the X Axis, no

action is taken. Standard clipping rules apply, if the value in the table is outside the

allowable range for the X axis.

Dependencies If either the first or last point in the array is outside the frequency range of the current input, an error

message is generated:

“-221. Settings conflict; Start or Stop Freq out of range for current input settings”

X Offset

Offsets the limit trace by some specified frequency (for frequency-based limit lines)

or a time (for time-based limit lines).
