SNMP Configuration
A SNMP configuration page is available as shown in the picture below:
Figure 10. SNMP Configuration Menu
The SNMP configuration menu allows to input the IP address of trap receiver and to change, enable and disable the trap community strings.
Host IP used to set the IP address of the computer with running management system, which receives the SNMP TRAP.
Parameters Read Community, Write Community, Trap Community are used for the SNMP exchange authenticity.
After modifying the values press the button “Save Config” to reboot the server and update the entered parameters.
Transmitter control
When the device completes start-up, operation will begin and the Control screen will appear as in Figure 11.
Parameters of the transmitter can be selected by selecting different menu items in the control page.

•
Attenuator parameter enables to decrease or to increase RF attenuator values (0…15 dB, 1 dB step).
Note
:
Attenuator
value may be changed step by step using Up/Down buttons at right side of parameter window or entered directly from keyboard. Take
in mind that some browsers (e.g. IE) don’t support Up/Down control element. In this case the appropriate value should be entered from keyboard.
•
Gain control allows to switch “On” or “Off” the AGC of the transmitter. It is used to set automatic RF level control for constant load to the laser. The
operating AGC level is set by the user when the button “Apply settings” is pressed. After that, RF level instability is compensated automatically by the
internal attenuator. If attenuator can’t compensate RF level drift, diagnostic error message “AGC out of range” is displayed.
•
“RF in” DC voltage enables to switch DC voltage on RF input socket to OFF (0 V) or ON: (+12 V). This voltage is used for powering external active
devices (for example antenna preamplifier) via coaxial cable.
After any control values are changed, press the button “Apply settings”.
Note
: DC on “RF input” socket (+12 V) can be dangerous for some devices.
To avoid mistakes when installing or operating the transmitter without external preamplifiers, it is recommended to use the DC voltage blocking coupler
(VBC). VBC protects test equipment, splitters, couplers, in-line attenuators and other equipment from damage.
Transmitter Status
Status page (Figure 12) shows actual status of the transmitter using error/warning descriptions.
Make sure that the transmitter is not indicating any error or warning.
