Checking Signal Status
This section describes how to use the CTS 710 to check signal status.
The CTS 710 continuously monitors the input signal for alarms,
errors, and failures and provides indicators for the current signal
status as well as indicating the history of the signal status.
Viewing Signal Structure
The quickest way to view the structure of a signal is to use
AUTOSCAN. AUTOSCAN analyzes the input signal and once a
signal is found, the CTS 710 synchronizes with the signal and
displays the structure of the signal.
To view signal structure using AUTOSCAN:
1. Connect a signal to the receiver input.
2. If a test is running, stop the test by pressing START/STOP.
3. Press the AUTOSCAN front-panel button.
While AUTOSCAN is running, several messages appear in the
display. While the CTS 710 searches for a signal it displays the
message: Please wait, autosetting to received signal. The CTS 710
scans all line rates and all receiver input connectors until it finds a
framed signal. When the CTS 710 finds a framed signal, the
instrument displays the message: Autosetting to received signal. If a
signal is not found, a message to that effect is displayed.
When the AUTOSCAN finishes, the CTS 710 displays the signal
structure in graphical form (see Figure 3–18). Use the knob to scroll
through the different active channels.
