MM = minutes [00 to 59], and SS = seconds [00 to 59]).

Set Date (dd/mm/yy) – Enter a date using the European time format DD/MM/YY (where

DD = day [01 to 31], MM = month [01 to 12], and YY = year [00 to 99]).

Test Mode – Use the drop-down menu to select test mode as follows:

• Normal Mode – This mode clears any test modes or loopbacks, and places the unit back

into an operational state.

• Tx CW – This test mode forces the modulator to transmit a pure carrier (unmodulated).

• 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. This

mode is used to check the carrier suppression of the modulator.

Click [Submit] once the desired Test Mode has been selected.
