Configures and/or performs an SNR measurement on the
selected (incoming) pair signal from a 100BaseT or
1000BaseT link. Measurement may be either immediate or
event triggered. Configurations are retained in test port and
in PowerShell PSA software.
trig off Configures measurement to start immediately upon
stat query. (Test Port wake-up default)
trig ext Configures measurement to start upon receipt of the
first Event Trigger following a stat query. (Not supported
in PSL-3000 and PSA-1200-PL chassis configurations.)
pair pairNo Specifies LAN PAIR to measure. Range is 1 to 4
where Pair 1 is TIA blue pair, Pair 2 is TIA orange pair, Pair
3 is TIA green pair, and Pair 4 is the TIA brown pair. If link
is 100BaseT, only Pair 2 or 3 may be specified and
depending on pair number, link will be forced to MDI_X or
MDI respectively. (This configuration not maintained if PVA
software closed. PVA software wake-up default = 3.)
link 100 Specifies SNR measurement to be performed on a
100BaseT (Fast Ethernet) link. (This configuration is not
maintained if PVA Software is closed. PVA Software wake-
up default.)
link 1000 Specifies SNR measurement to be performed on a
1000BaseT (Gigabit Ethernet) link. (This configuration is
not maintained if PVA Software is closed.)
avg nAvgs Specifies the number of raw measurements to
average into each channel response coefficient. Range is
1 to 64. (Test Port wakeup default is 10).
timeout 10 specifies that an Event Triggered measurement
should time out if no trigger is received within 10 seconds
following stat query. (Test Port wakeup default.)
timeout 100 specifies that an Event Triggered measurement
should time out if no trigger is received within 100 seconds
following stat query.

DISCONNECTED
Configures and performs a Bulk Echo Response
measurement on selected pair using the calibration data
previously acquired for specified LAN pair, test port, and PVA
instrument. Measurement may be either immediate or event
triggered. Configurations are retained in test port and in
PowerShell PSA software. The bulk echo response
measurement returns a single Return Loss (dB) figure for the
selected pair.
trig off Configures measurement to start immediately upon
stat query. (Test Port wake-up default)
trig ext Configures calibration to start upon receipt of an
Event Trigger following a stat query.
pair pairNo Specifies LAN PAIR to measure. Range is 1 to 4
where Pair 1 is TIA blue pair, Pair 2 is TIA orange pair, Pair
3 is TIA green pair, and Pair 4 is the TIA brown pair. (This
configuration is not maintained if PSA Software is closed.
PSA Software wake-up default = 3.)
avg nAvgs Specifies the number of raw measurements to
average into each channel response coefficient. Range is
1 to 64. (Test Port wakeup default is 10).
timeout 10 specifies that an Event Triggered measurement
should time out if no trigger is received within 10 seconds
following stat query. (Test Port wake-up default)
timeout 100 specifies that an Event Triggered measurement
should time out if no trigger is received within 100 seconds
following stat query.
