Saving patterns
If you open an existing saved pattern from disk and make changes to it, you will
be reminded to save the changes before you can close the file or exit the program.
If you receive a pattern from a gigaBERT to the Tektronix Pattern Editor you
must remember to save the file to disk before closing the file or exiting the
program. The program will not remind you to do so.
Depending on the format selected, if you attempt to save a file with any cells not
completely filled, the Editor will automatically insert zeros to complete the cell.
For example, if the HEX format is chosen and the last cell has an entry of "5", the
editor will save the cell with an entry of "05".
If a pattern of more or less than whole bytes is saved, the partial byte will be
saved with a whole byte entry whose needed bits are correct and the excess being
set to zero(s).
The BACKSPACE key works only within a cell.
Sending Patterns to or from a gigaBERT
Although you can save a pattern with a bit order of either LSB or MSB, you must
set the gigaBERT separately to reflect the correct order. The program does not
automatically set, or read, the gigaBERT to match the order of the file being sent.
If you should have a problem sending a pattern to a gigaBERT or receiving a
pattern from a gigaBERT, there may be a problem with the identification string
that is stored in the gigaBERT. Please consult the remote commands section of
the respective manual for the instrument. Normally, unless you change the
identification strings and prompt, they will remain at the default setting.
Another method for restoring the correct gigaBERT identification string and
prompt is to revert the gigaBERT to its default factory configuration. Reverting
the instrument to its default condition will destroy any saved patterns and clock
frequencies (Tx). To do this, turn the instrument off and then do the following:
For the gB1400 Transmitter: Simultaneously hold in the OUTPUT Clock and
PATTERN Clear buttons and turn the instrument on.
For the gB1400 Receiver: Simultaneously hold in the ERROR DETECTION
Clear and PATTERN Clear buttons and turn the instrument on.
For the gB700 Transmitter or Receiver: Simultaneously hold in the PATTERN
MSB, PATTERN Clear, and VIEW ANGLE buttons and turn the instrument on.
Hold the buttons in until RAM CORRUPTION or DEFAULT SETTING shows
in the display. Retry sending or receiving a pattern.
