[802.3_10SPE] Proposed resolution to Lennart's 'shall be tested' comments



Attached is the proposed resolution to comments from Lennart involving “shall be tested” –  we plan to resolve this tomorrow (Tuesday) morning.

General approach – change these to the formula “When texted using the test fixture shown in Figure xxx-yyy and the transmitter in test mode z, the transmitter …”

 

See proposed resolutions to comments 301, 302, 308, 309, 310 attached, and example below using comment 301:

 

Cl 146 SC 146.5.4.1 P 140 L 48 # 301

Comment Type TR

"Transmitter output voltage shall be tested using test mode 1 in combination with the test

fixture shown in Figure 146-17."

We can't put requirements on the tester, only on the device.

SuggestedRemedy

Rewrite the requirement:

"When tested with the test fixture shown in Figure 146-17 in test mode 1, the transmitter

output voltage shall ... <show some property>."

Possibly the very next sentence already covers this. In that case, make the quoted

sentence informative.

 

PROPOSED ACCEPT IN PRINCIPLE.

Change “Transmitter output voltage shall be tested using test mode 1 in combination with the test

fixture shown in Figure 146-17. The transmitter output voltage shall be 2.4 V ± 5% peak-to-peak (for the 2.4 Vpp operating

mode) and 1.0 V ± 5% peak-to-peak (for the 1.0 Vpp operating mode). "

To: “"When tested with the test fixture shown in Figure 146-17 and the transmitter in test mode 1, the transmitter

output voltage shall be 2.4 V ± 5% peak-to-peak (for the 2.4 Vpp operating mode) and 1.0 V ± 5% peak-to-peak (for the 1.0 Vpp operating mode).”
