Ports of the Module
When you get a new DG3000 Logic Signal Output Module, first be familiar with the
ports and markings on it. There are three main ports: port connected to DG3000, a
digital logic output and an analog logic output, as shown in Figure 1-1.

As shown in Figure 1-2, to use the module, please connect this port to the
“DIGITAL OUTPUT” connector at the rear panel of DG3000 with the provided cable
as described in “Appendix A”.
Figure 1-2 Port used for connecting to DG3000
The analog logic output port and the pin definitions are shown in Figure 1-3. To
use it, please connect the provided logic analyzer testing wires to this port;
connecte the other ends of the testing wires to the input of a logic analyzer which
will verify the output signal of the module. The logic analyzer testing wires can also
be used to transform the analog logic output.

To Connect the Module
The Logic Signal Output Module is an optional accessory of the DG3000 Series
Function/Arbitrary Waveform Generator. Connect the module to a DG3000 as
shown in Figure 1-5. Make sure that the power is off before and during the
connection. Power up the instrument, the DG3000 will confirm if the module has
been successfully installed by displaying the message: “Digital module is installed”.
Otherwise, repeat the above setup process until the screen shows the success
message.
Figure 1-5 Connect the module to DG3000
WARNING When connecting the module to a DG3000, the power must
be turned off.

DG3000 provides a switch function to control the power modes of the module.
Press Utility Output Setup Digit-Modu, as shown in Figure 1-6, there are
two power states: “Power-On”and “Power-Off”.
The module supports two work modes: “Depend”and “Independ”.
At the “Depend” mode, all the analog waveforms output are disabled, the output
rate and phase of digital output will have not limit.
At the “Independ” mode, both the module and DG3000 can works normally.
However, the output rate and phase of module will have “some limit”(See the
following prompt message).
Figure 1-6 Choose “Independ” mode
Examples in this manual use the “Independ” mode to introduce the functions and
operation methods of the module, as shown in Figure 1-6 Choose “Independ”
mode, the Arb button will blink indicating that the modified settings have not
been activated, Press Arb again to execute.

Limit of the output rate
In “Independ” work mode, the output rate has the following limit:
RS232: (100MBps/120MBps) / (2× N), (N=1, 2, 3, …)
SPI: (100Mbps/120Mbps) / (2× N), (N=1, 2, 3, …)
IIC: (100Mbps/120Mbps) / (8× N), (N=1, 2, 3, …)
PO: (100Mbps/60Mbps) / N, (N=1, 2, 3, …)

easy-to-use graphical displays for: Communication Protocol Interface, and Data
Editing Interface.
Communication protocol interface allows users to configure the system:
Select digital communication protocols
Select multifarious code patterns or user-defined patterns
Set the data output length
Select data transmission rate or user-defined rate output
Set trigger mode and trigger level
Configure output channels with various signal line.
Data Editing Interface allows users to:
Edit data in hexadecimal or binary form
Store the waveform data in non-volatile memory,
Recall and edit stored data.
