Chapter 10 Utility and System Settings RIGOL Overview Press Utility at the front panel to open the operation interface as shown in the figure below. This interface displays the current channel output configuration, channel coupling configuration and system parameters. Figure 10-1 Utility Interface 1. 2. 3. 4. 5. 6. 7. 8. 9. 10-2 CH1Set: set the output parameters of CH1. CH2Set: set the output parameters of CH2. I/O Setup: set the I/O interface parameters. System: set the system parameters.
Chapter 10 Utility and System Settings RIGOL Channel Setting This section takes CH1 for example to illustrate how to set the channel. The setting method for CH2 is quite the same. Sync DG4000 could output the sync signals of basic waveforms (except Noise), arbitrary waveforms (except DC), Harmonics, Sweep signal, Burst signal and modulated signal from a single channel or two channels at the same time. The sync signal is output from the [Sync] connector at the front panel.
Chapter 10 Utility and System Settings RIGOL z z z z z a Square with 50% duty cycle and takes modulating frequency as reference. It is TTL high level in the first half period of the modulation waveform. In external modulation mode, there is no sync signal output. For ASK, FSK, PSK, BPSK, QPSK, 3FSK and 4FSK, the sync signal takes ASK/FSK/PSK/BPSK/QPSK/3FSK/4FSK Rate as reference and is a Square with 50% duty cycle. For ASK, FSK and PSK, in external modulation mode, there is no sync signal output.
Chapter 10 Utility and System Settings RIGOL Output Polarity Set the signal on the [Output1] connector as normal or inverted. Waveform inverts relatively to the offset voltage. Press Utility Æ CH1Set Æ Output to select “Normal” or “Invert”. The default is “Normal”. The waveform of the first half period of the cycle is positive in “Normal” mode and negative in “Invert” mode.
Chapter 10 Utility and System Settings RIGOL Resistance Setting Figure 10-3 Resistance Setting The generator will adjust the output amplitude and offset voltage automatically once the resistance setting is changed. For example, the current amplitude is 5Vpp. At this point, change the output resistance from 50Ω to HighZ and the amplitude displayed on the screen will double to 10Vpp. If the output resistance is changed from HighZ to 50Ω, the amplitude will reduce to half of the previous value (2.5Vpp).
