Choose the menu buttons on the left-hand side of the screen to modify any of the following
attributes:
•
PSK Data
. A table used to program a sequence of phase changes, as shown in step 10.
•
CW Control
. Used to turn the carrier waveform
CW OFF
or
CW ON
.
•
CW Frequency
. The frequency of the sinusoid carrier waveform.
•
Symbol Rate.
The rate at which the symbols step through. The rate can be programmed
within the range of 1 S/s to 1 MS/s (when the length of the symbol is a single bit).
•
Marker
. Defines an index point in the PSK sequence at which the Sync Output generates a
marker pulse.
•
Amplitude
. The amplitude of the carrier wave (in Volts peak-to-peak).
•
Offset
. The amplitude (in VDC) offset with reference to zero-level amplitude.
