Figure 5-24: BPSK user interface
How to set the parameters of BPSK
(1) Press the Mode function key,press the NextPage softkey three more
times,then press the BPSK softkey to enter BPSK user interface.
(2) Select carrier wave shape:
The carrier wave can be Sine, Square, Ramp, or Arbitrary wave (except
DC). Press , , , or to select a desired carrier wave
shap.
(3) Set carrier wave parameters:
Press the wave shap key of the selected carrier wave to display the
waveform and parameters of the carrier wave. You can change the
parameters of the carrier wave. Press Mode to return to the modulation
mode interface.
(4) Select modulating wave source:
BPSK uses internal modulation source. Press the DataSource softkey to
select PN15, PN21, 01 Patt, or 10 Patt as the modulating wave source.
(5) Set BPSK rate:
Press the Bit rate softkey to set the BPSK rate. The rate at which the
output phase shifts between the carrier phase and the modulating phase
is determined by BPSK rate (for internal source). The range is 2 mHz –
1 MHz.
(6) Set BPSK phase deviation:
Press the Deviation softkey to set the modulating phase deviation.
