The following sections show how to set up the logic analyzer and to do timing analysis using data from a simple D-type ip-op. Flip-ops serve as building blocks in digital systems. Although most ip-ops are buried inside complex ASICS and other devices, they are useful for showing hardware debugging techniques using a logic analyzer. T he examples in this document use only a few channels to acquire data. However, you can use the same concepts with hundreds of channels.

Create New Channel Groups
Channel groups are a collection of probe channels used to accomplish specic tasks. Probe channels are typically organized from the most signicant bit (bit 7) to the least signicant bit (bit 0) as shown in the probe channel table. Each probe channel can have a unique name that appears in the data windows.

Analyzing Data
Your instrument has several tools for analyzing data, such as zooming data, measuring data, and viewing data with MagniVu high-resolution timing. This section provides concepts and procedures for analyzing data in the Waveform window. Some of these features also apply to the Listing window; refer to the online help for more details.
Zooming Data
To zoom data in the Waveform window:
1. Click and drag from left to right over the area you want to zoom.
2. Click the Zoom In button a few times to zoom the timing data samples.
Quick Tips
Click and drag from the right to the left to zoom to the previous selection.
Use the Zoom In and the Zoom Out buttons in the toolbar as an alternative m ethod of zooming data.

Measure Waveform Data using Cursors
Use the Snap to Edge feature with cursors in the Waveform window to measure the time between waveforms.
1. Point the mouse at Cursor 1 over the
waveform that you want to measure.
2. Click and drag Cursor 1 toward a leading
or trailing edge of the waveform.
3. Release the mouse to snap the cursor to
the next waveform edge.

You can use the Delta-Time toolbar to measure time between any two marks. Select the marks from the drop-down lists in the toolbar.
Using the Data Measurement Window
Use the Data Measurement window to quickly take measurements in the Waveform or Listing window.
1. Click Measurements.
2. Click and drag the Period icon to the
Clock waveform, and release.
The selected measurement will be added to the Data Measurement window at the bottom of the display.
3. Repeat for any other measurements.
4. Click the Statistics tabintheData

iView Integrated Measurements
You can use the iView feature to connect an external Tektronix oscilloscope to the logic analyzer, acquire data from both instruments, and display the results on the logic analyzer. This is useful for displaying the analog components of a signal in the same data window as the digital components.
In the following examples the logic analyzer and the oscilloscope will acquire the same data. The logic analyzer captures the digital components and the oscilloscope captures the analog components.
Use the following steps to set up the oscilloscope for these examples. Refer to the documentation that came with your oscilloscope for operating instructions.
1. Connect the oscilloscope probe to the same signal source as the logic analyzer (for this example, connect to the Q output of the ipop).
2. Power on the oscilloscope.
3. Press the Default Setu p button on the oscilloscope, and then press the Autoset button. You should have a signal on
the oscilloscope screen.
