Keyboard and Display Conventions
Keyboard and Display Conventions
The conventions used in this manual to illustrate instrument keys and display
information are as follows:
This is an example of a hardkey. Hardkeys (located to the right of the display) are
used to give access to different sets of instrument settings, or select dedicated
instrument functions. The key shown here displays the transmit settings.
This is an example of a softkey. Softkeys (located below the display) are used to
select instrument settings. The values associated with softkeys change as you move
the display cursor from one instrument setting to another.
These are the cursor control keys. They are used to move the display cursor from
one instrument setting to another.
This is an example of a pop-up menu. Pop-up menus are an alternative way of
selecting instrument settings (instead of using softkeys). To access a pop-up menu,
highlight an instrument setting, then use the key to complete the selection.
This symbol (when it appears next to settings on the display) indicates that there is a
pop-up menu associated with the instrument setting. To access a pop-up menu,
highlight the instrument setting which has this symbol, then use the key.
This symbol appears at the bottom right of the display when an optical transmit
module is fitted to the instrument. The symbol’s background changes from black to
yellow when the optical output is switched on.

Monitoring Status Alarms
The LED indicators provide information about the current status of the instrument’s
receiver. If an alarm has occurred during the current test period, the HISTORY
indicator lights up. The figure below shows the status indicators for the dual
standard SDH/SONET option (Option 002).
These three indicators change
from green to red when an alarm
conditions occurs.
Press and hold this key to view the alarm history. When this key is
released the status indicators return to displaying the current status.
The HISTORY indicator lights when an alarm has occurred during
the current test period.
SHOW
Press this key to reset the HISTORY store (all lit indicators
extinguish). If an alarm condition is present during the reset, then
the indicators associated with that alarm will remain lit after the
reset. The resetting of the HISTORY store also occurs when you
start a new test period.

Introducing Smart Test
Introducing Smart Test
The Smart Test feature simplifies instrument operation by:
• Allowing the instrument to auto-configure on the incoming signal (Smart Setup).
It will attempt to identify the signal structure.
• Allowing you to quickly access the most commonly used instrument features
(Smart Tests):
• Signal quality.
• Functional tests.
• Jitter tests (Available with J1409A).
• Settings (stored, logging, Tx/Rx coupling and trigger output enable).
To run Smart Setup:
1Ensure a valid signal is connected to one of the instrument’s Receive ports.
2Press .
3With Smartsetup highlighted, press to auto-discover information
about the receive signal. Or press to exit Smart Tests.
