Setting the Pass/Fail Limits

Setting the Pass/Fail Limits
The measurement limits setting allows you to alter the value of the upper and lower test limits. Center segment limits are set in dBm and are absolute limit values. The first and second segment limit values are set in dB and are limit values relative to the center segment. The settings you choose define the location of the limit lines displayed on the screen. These settings will result in a pass/fail flag being displayed on the screen above the limit line: a red triangle with a "F" is a fail, a green circle with a "P" is a pass.
You can set a variety of limit configurations to suit your needs: a single upper or lower limit, an upper and lower limit pair , a segmented upper or lower limit, or an upper and lower segmented limit mask . You can specify a maximum of one center segment, two lower segments, and two upper segments.

To Set the Measurement Upper and Lower Limits:

Step
Notes

1
[Setup]

2
[Limits]

3
Set the upper limit.

On [Limits] select Upper

4
Set the center segment limit.

On [Segments] select Center

5
On [Center Segment] select On or Off.
Enables you to toggle the measurement limit line segment function On (active) and Off (inactive).

If set to On, an upper limit line with a pass or fail icon above the line is displayed on the screen. This enables you to set the center segment limit value and the width of the center segment. (Center segment width (Center Span) is unavailable unless the first segment is turned on.) Any measured value that exceeds the upper limit will result in a failure indication.
If set to Off, neither limit lines nor pass fail indicators are displayed.

6
Set the center segment limit value.

[Center Level]
Enter the number on the numeric keypad.
[dBm]
Maximum Upper limit: 50 dBm to -150 dBm (if a lower limit is set, the upper limit should be set higher than the lower limit)

7

If you only need an upper limit line, stop here.
If you need a lower limit line:

On [Limits] select Lower
Repeat steps 4, 5, and 6.

For a segmented limit line, proceed with step 8.

8
Set the first segment limit.

On [Segments] select 1st

9
On [1^st Segment] select On or Off.
Enables you to toggle the measurement limit line segment function On (active) and Off (inactive).

If set to On, a left and right upper limit line segment with a pass or fail icon above each segment is displayed on the screen. This enables you to set the first segment left and right limit values and the width of the left and right first segment. (The first segment width (Span) is unavailable unless the second segment is turned on.) Any measured value that exceeds the upper limit will result in a failure indication.
If set to Off, neither limit lines nor pass fail indicators are displayed. Nor are second segment functions available.

10
Set the first segment left and right limit values.

On [1^st Segment] select Left.
[Level]
Enter the number on the numeric keypad.
[dB]
On [1^st Segment] select Right.
Repeat steps b, c, and d.
Maximum Upper limit: 50 dBm to -150 dBm (if a lower limit is set, the upper limit should be set higher than the lower limit)

11
Set the center segment width value.

On [Segments] select Center
[Center Span]
Enter the number on the numeric keypad.
[GHz], [MHz], [kHz], or [Hz]

12

If you only need a two segment limit line, stop here.
For a three segment limit line, proceed with step 13.

13
On [Segments] select 2nd

14
On [2^nd Segment] select On or Off.
Enables you to toggle the measurement limit line segment function On (active) and Off (inactive).

If set to On, a left and right upper limit line segment with a pass or fail icon above each segment is displayed on the screen. This enables you to set the second segment left and right limit values. Any measured value that exceeds the upper limit will result in a failure indication.
If set to Off, neither limit lines nor pass fail indicators are displayed.

15
Set the second segment left and right limit values.

On [2^nd Segment] select Left.
[Level]
Enter the number on the numeric keypad.
[dB]
On [2^nd Segment] select Right.
Repeat steps b, c, and d.
Maximum Upper limit: 50 dBm to -150 dBm. If a Lower Limit is set, the Upper Limit should be set higher than the Lower Limit)

16
Set the first segment width value.

On [Segments] select 1st
[Span]
Enter the number on the numeric keypad.
[GHz], [MHz], [kHz], or [Hz]

17
Set the lower limit.

On [Limits] select Lower
Repeat steps 4 through 16 as appropriate for the number of segments you need.
Maximum Lower Limit: dBm to -150 dBm. If an Upper Limit is set, the Lower Limit should be set lower than the Upper Limit)
