Module Parameter Panel -
The module parameter panel is accessed by the third tab below the tool bar and menu bar, near the top of the application window. From this panel you can set the MUXDAC sampling select window, set whether to stop or start the DAC and memory, and see the actual memory data.
DAC Control
DAC Running/Reset
Stops or resets the DAC. While the DAC is stopped, the waveform is no longer output.
SEL
Selects which of four possible times to sample the data. The optimal SEL setting changes for different clock frequencies, and at least one SEL setting allows data to be sampled near the most open part of the eye between signal switching. The SEL setting for the currently set frequency can be saved in the signature panel.
Memory RUN/STOP
Stops the waveform at the current memory address. When memory is stopped, you can go through each memory address manually and see the waveform data stored in each address using the Address Reset and Address Clock buttons.
Memory RUN/STOP is also useful if you wanted to change the input clock frequency in the middle of a waveform. You click the Memory STOP button to temporarily stop the waveform, change the input clock frequency, and then click on Memory RUN button (same button) and the waveform will start again at the new frequency. Be sure also to adjust the value in the Clock Frequency bar in the Signature panel to ensure that the output will match the values desired.
Memory Address
Address Reset
When memory is stopped, you can click this button to view the waveform data for each of four memory banks at the first memory address.
Address Clock
Increments memory location by 1 so you can view output data values of sequential memory addresses. Only enabled when memory is stopped.
Address
Displays the current memory address. Not available unless memory is stopped by clicking on Memory STOP. You may type in a memory address in this box to view the data at that address.
Data
Displays the waveform data word in hexadecimal of the current memory address for each of four memory banks.
