Table 36.Error Code descriptions (cont.)
Error in acquiring waveform from oscilloscope
E111 Timeout occurred while
acquiring a waveform This is the GPIB timeout information
that appears when the application is
acquiring the waveform
Make sure the probe and compliance test
fixture connections are proper. Reacquire
the new waveform
E112 Error in turning on a channel The application failed to turn on the
live channel selected as source(s) Make sure the probe and compliance test
fixture connections are proper. Reacquire
the new waveform
E113 Error in importing waveform
from instrument
The operation of importing the
waveform from the acquisition memory
failed. This will fail whenever there is
no valid waveform in the acquisition
memory
Make sure the probe and compliance test
fixture connections are proper. Reacquire
the new waveform
Packet Detection Warning
Try acquiring the signals again by pressing
Run button E201 No EOP region found Testing will be performed on an full
USB2.0 packet, which includes an
EOP region. If no EOP region is
found, the results might be incorrect
since testing will be performed on a
incomplete packet. For Upstream
signal quality testing, EOP must be
present
E202 Number of record points (data
points) are too few to process At least 500 record points are required
to perform an operation. The
application automatically sets the
required record length. The user
should not change the record length
Try acquiring the signals again the
pressing Run button
E203 Idle region is not found after
EOP As part of the USB2.0 packet
description, an EOP region follows an
idle region. If no idle region is found, it
may lead to incorrect results
Try acquiring the signals again by pressing
the Run button
E204 Reconfirm acquired data before
computing the results
As part of the USB2.0 packet
description, a minimum of three J-K or
K-J state transitions are expected. An
absence of these transitions may lead
to incorrect results
Try acquiring the signals again by pressing
the Run button
Signal rate measurement errors or warning
E301 There should be at least two
Cross-Over time values to
calculate the signal rate
For signal rate calculations, the
application expects a minimum of two
Cross-Over points
Try acquiring the signals again by pressing
the Run button
E306 Device/ File doesn't match with
the selected speed The signal rate should be within 30%
of the specified signal rate of the Low,
Full and High Speed signals
Please check the speed of the connected
device. Ensure that the selection in the
application is the same. For example, if a
Low Speed unit is under test, make sure
Low Speed is selected in the application
