• Unit Name – The product (e.g., CTOG-250) is identified here.
• System Contact / System Location – E-mail and telephone contact information for Comtech
EF Data Customer Support are provided here.
Enter the desired information. Click [Submit] to save.
• Set Time (hh:mm:ss) – Use the HH:MM:SS time format to set the time, where HH=hour [00
to 23]; MM=minutes [00 to 59]; and SS=seconds [00 to 59]).
• Set Date (dd/mm/yy) – Use the DD/MM/YY European time format to set the date, where
DD=day [01 to 31]; MM=month [01 to 12]; and YY=year [00 to 99].
Set the Time and Date, and then click [Submit] to save.
• Circuit ID – Enter a Circuit ID string consisting of 4 to 24 characters, and then click [Submit]
to save.
• G.703 Clock Extended Mode – Use the drop-down menu to select this operating mode as Off
or TxLock, and then click [Submit] to save.
• 10 MHz Internal Adjustment – Enter a value from (-)999 to (+)999 to set the adjustment for
the Internal 10 MHz High Stability Reference.
• External Reference Frequency – Use the drop-down menu to select this operating mode as
Internal, External 1/2/5/10 MHz, or Internal 10 MHz plus External.
Set the 10 MHz Internal Adjustment and External Reference Frequency parameters, and
then click [Submit] to save.
• Test Mode – Use the drop-down menu to select this operating mode as follows:
o Normal Mode – This mode clears any test modes or loopbacks, and returns the unit to its
operational state.
o Tx CW – This test mode forces the modulator to transmit a pure carrier (unmodulated).
o Tx Alt 1/0 – This test mode forces the modulator to transmit a carrier modulated with an
alternating 1,0,1,0 pattern, at the currently selected symbol rate. This causes two discrete
spectral lines to appear, spaced at +/- half the symbol rate, about the carrier frequency.
Use this mode to check the carrier suppression of the modulator.
Select the desired mode, and then click [Submit] to execute.
