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. Click [Submit] to save.
