Channel Set
For DG1000Z, the function and setting method of CH1 are the same to those of CH2.
This section takes CH1 for example to illustrate how to set the channel. To set the
output parameters of CH2, please press CH1|CH2 to select CH2 and refer to this
section to set the parameters.
Sync Set
DG1000Z 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 from two channels at the same time. The instrument
outputs the sync signal from the [CH1/Sync/Ext Mod/Trig/FSK] connector at
the rear panel.
1. Sync On/Off
Enable or disable sync signal at the [CH1/Sync/Ext Mod/Trig/FSK]
connector. Press Utility  Channel Set  Sync Set  Switch to select “On”
or “Off” the output of the sync signal. The default is “On”, namely transmitting
the sync signal to the [CH1/Sync/Ext Mod/Trig/FSK] connector. When sync
signal is disabled, the output level at the [CH1/Sync/Ext Mod/Trig/FSK]
connector is logic low level.
2. Sync Polarity
Set the sync signal on the [CH1/Sync/Ext Mod/Trig/FSK] connector at the
rear panel as normal or inverted. Press Utility  Channel Set  Sync Set 
Polarity to select “Normal” or “Invert”.
 Normal: outputs normal sync signal.
 Invert: outputs inverted sync signal.
3. Delay Time of Sync Signal Output
Set the delay time of the sync signal output of the [CH1/Sync/Ext
Mod/Trig/FSK] connector at the rear panel relative to the signal output of the
[CH1] connector at the front panel. Press Utility  Channel Set  Sync Set
 Delay, input the desired value using the numeric keyboard and select the
desired unit from the pop-up menu. The range is from 0.0ns to the currently
selected period of the carrier waveform and the default is 0.0ns.
Note: when modulation, sweep or burst is enabled, the delay setting is invalid.
