DISCONNECTED
Configures and performs an Crosstalk Response calibration
using the opposite test port on the same PVA-3102 test
blade connected via the dedicated test cable (see Section
2.2.6). Calibration data for each LAN pair on each Test Port
will be stored for use by future 1000BaseT Crosstalk
Response measurements involving that same Test Port.
cal Initiate (in concert with stat query) a Crosstalk Response
calibration.
trig off Configures calibration to start immediately upon stat
query. (Test Port wake-up default) NOTE: Event trigger
“ext” not supported for PSD calibrations.
pair pairGrp Specifies 1000BaseT LAN PAIR GROUP to
calibrate. Range is 12, 13, 14, 23, 24, and 34 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 = 23.)
avg nAvgs Specifies the number of raw measurements to
average into each crosstalk finished measurement.
Range is 1 to 64. (Test Port wakeup default is 10).

4.9. DUT Transmitter Measurement Configurations and Queries
The PVA-3000 offers measurement capabilities useful to both transmitter and receiver testing. The following
commands and queries are specific to transmitter and interface measurements described earlier in Sections 1.3 and
2.2.2.
All measurement queries require link to the port-under-test. Certain measurements such as PSD, Echo, and Xtalk will
attempt to force re-links to specific link configurations required by those measurements. If a channel is unlinked upon
starting any measurement or if the channel fails to link after configuring the required link, the measurement will return
with the UNLINKED state. If the channel drops link during a measurement, the measurement will return the
LINK_DROP state.
These commands accept the broadcast configuration where port= 99,99 when configuring meters, but not when
performing measurements with the stat query argument.

Rx_Power
(dB_Nominal)
Measures the PVA test port incoming wideband power level
given a 100BaseT or 1000BaseT link. Measurement is only
immediate triggered and does not retain configuration.
For 1000BaseT, meter will report power on each of four pairs
and average power on all 4 pairs. For 100BaseT, will
automatically discover Rx pair and report power on that
single pair.
Power units are dB(Nominal), that is, power in dB relative to
a nominally ideal 100BaseTx or 1000BaseT signal.
pairNo: Report measured power on a specific pair (1,2, 3, or
4). If linked 100BaseT, pairNo is restricted to 2 or 3.

Measures 1000BaseT (gigabit) timing skew on all 4 LAN
pairs. Measurement is only immediate triggered and does
not require or retain configurations.
