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 mode is used to check the carrier suppression of the modulator. Selecting
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.
Click [Submit] once the desired Test Mode has been selected.
