UTG9000T Series Function Abitrary Waveform Generator
BPSK bitrate range cam set to 1μbps~2Mbps, the default range is 100bps. Rotate multifunction knob, push direction
key or tap Bitrate tab to pop-out visual numeric keyboard to enter values and select unit in modulation setting
interface.
Phase settings
1) Phase1 is the carrier wave phase, the default value is 0°. Rotate multifunction knob, push direction key or tap
Phase1 tab to pop-out visual numeric keyboard to enter values and select unit in modulation setting interface.
2) Phase1 is the modulating phase, it means the phase changes between the BPSK-modulated wave and the carrier wave
phase. The BPSK modulating phase range can set to 0º~360º, the settings steps is the same as Phase1.
Comperhensive example
In BPSK modulation mode, set an internal 2kHz,2Vpp sine wave as a carrier wave, set the initial phase to 90°,
1kbps shift frequence between in the carrier wave phase and the modulating wave phase, set PN Code to PN15.
The settings steps as following,
1)
Turn on BPSK modulation mode: tap CH1→Modulate→BPSK accordingly.
2)
Set the parameter of the carrier wave signal
Tap Base to select sine as the carrier wave (the default option is sine), so this step has no change.
