The LA-4000 series of parallel port and USB logic analyzers offer all of the features and performance you have come to expect: high speed clock rates, deep data buffers, sophisticated triggering, easy data management and large color displays.
The PC Based instruments are controlled with easy to use Windows software. This allows for more organized data display (with color coded data and increased screen size), intuitive user interface, and data management (file saving, loading, sharing and exporting to other software and reports).
Our logic analyzers connect to your PC's parallel port or USB port and take advantage of your large color screen, disk drives and printers. They are compact and don't have screens, drives, knobs or buttons - saving you money and space.
The LA-4000 PC Based logic analyzer series can be configured to be a pattern generator with the purchase of optional pattern generator pods. |
| Features |

Logic Analyzer FrontPanelTM Software
The software has the familiar feel of a windows program while giving you a rich set of Logic Analyzer commands. Parameters can be changed on the fly while acquisitions are repeating and the results seen on the updated display. All functions are accessed through pull down menus and dialog boxes. Toolbar icons offer quick access to more frequently used operations.
| Timing Window |
| The data is displayed as a timing waveform. Each channel is displayed with a user-specified color and label. Channels can also be displayed in any sequence and can also be grouped into busses and viewed in ASCII, HEX, decimal, binary, or user defined mnemonics. The display can be zoomed in/out and scrolled to show just a few samples or the entire buffer. This window also has 4 data cursors that can be used to measure time between events or as markers for places of particular interest. |

| Statelist Window |
 |
Data in the Statelist window is organized into groups and displayed in a numeric format (ASCII, binary, HEX, decimal or user defined mnemonics). These groups are user defined and can have from 1 to 32 channels in them. This window has 4 data cursors that can be used to measure time between events or as markers for places of particular interest. These are the same cursors as the ones in the Timing window and can be used as a reference point when viewing data in both windows. |
| Search Function |
 |
Sorting through all your data is easier with our search feature. You can specify a search pattern, including Don't Care bits, in any of the shown numeric bases. Then just click on the forward or backwards search to find what you are looking for. |
| I2C Monitor Software (optional) |
 |
- View I2C codes from a separate window within our Windows based control software.
- Displays I2C commands. Start, Stop, Read, Write, Slave address, Address, Data, ACK and NACK.
- Displays Timing of all activity on the Clock and Data lines showing you everything that happened, including valid I2C codes, glitches, timing errors and other non-I2C data.
- Since this is a logic analyzer, you have plenty of other channels to monitor the rest of your circuit while still viewing the I2C bus.
- Compare I2C codes with actual circuit behavior. Are your commands actually doing what you expected? You have all of the logic analyzer's resources to verify and debug your circuit response.
- What makes this product so superior to other I2C Monitors is that you are also be able to see all activity on the Clock and Data lines in Timing and Statelist display.
|
| Cursor Controls & Settings |
 |
The current position of the cursors is shown here. Selecting a specific cursor or display window and then clicking the arrows allow precise changes of position. The cursors can also be quickly repositioned by clicking on the cursor and dragging it.
The position, both absolute and relative to the trigger, can be shown in time units or data sample numbers. |

File Save/Export
The logic analyzer data can be stored on your PC in a number of ways:
- Files can be saved to disk for future viewing
- Data can be exported in "CSV" format to programs like Mathcad, Excel, Word, etc...
- You can paste screen images into your reports using programs like Word, Excel, image editors, etc...
- Data can even be shared with other computers. You don't need to have our logic analyzer connected to a computer to view the data files. You can capture data in the lab and view it in your office or you can email it to other engineers at remote locations for analysis
|
|
|
|
|
|
Deep Data Buffers (up to 512K samples per channel)
Simply put, the deeper the buffer the better. Our data buffer gives you the flexibility to store a great number of events surrounding the trigger. Sometimes it is difficult to pinpoint the exact event that you want to trigger on. With our system you don't need to know exactly where to trigger since our large buffer will capture so many events. And of course you can capture long events that other analyzers may cut off. Also, you can maintain higher sampling rates to get more detail without running out of buffer space.
|
|
|
|
|
|
Continuously Variable Pre/Post Trigger Position
The continuously variable pre/post trigger positioning enables the user to control the amount of data recorded before and after the trigger event. The trigger cursor can be positioned anywhere in the buffer (up to 512K) so that can see a long train of events that led up to the trigger condition, a long series that followed the trigger or many events surrounding it.
|
|
|
|
|
|
Advanced Triggering
Our logic analyzer captures the data that is important to you. Its sophisticated 16 level triggering (up to 160 bits each) lets you fine tune the exact point to start capturing. Multilevel triggering is used to make the logic analyzer look for a sequence of events to happen (i.e. address xxxx1110xx111x0x followed by address 11xx1110xx111x0x).
| Number of Levels |

Over Voltage Protection
Unlike other analyzers, our LA-4000 series logic analyzers are designed to protect itself from over voltage damage. If you accidentally touch the wrong pin, you are unlikely to damage anything. The analyzer's logic inuts can handle +/- 120V continuously.
|
|
|
|
|
|
Pattern Generator Output (optional)
With the optional 100 Mpoints/s pattern generator pods the LA-4000 series logic analyzers can be configured to work as a pattern generator. As few as 16 or as many as 160 channels (max # of channels depends on logic analyzer model) can be configured to output. The remaining channels will continue to function as logic analyzer inputs. The output data can be generated using our software, from your files or acquired through the logic analyzer channels. Output voltage: High: Minimum 2V at 32mA. Low: Maximum 0.55V at 64mA.

Standard Accessories
| The standard logic analyzer kit includes software, logic pods, clips and wires. |
| Clips |
 |
The logic analyzer ships with a full set of color coded clips and wires. The double gripper is designed for hard-to-make test connections of varying sizes and shapes. The narrow configuration allows stacking of the test connectors side-by-side for high-density IC packages and surface-mount components. Two 0.025" square pins permit connection to 0.025" square or .030" round push-on adapters or jumpers.
Other options include:
Connecting the wires directly to 0.025" posts on your board and connecting your wires/cables to the posts on the logic pod. |
| Wires |
| Wires are used to connect the logic analyzer to either the clips, or directly to the circuit under test. One wire is provided for each channel and two for grounding each data pod. The wires are 10 inches long and have female connectors at each end. These plug onto standard 0.025" posts on your circuit or to the pins on the clips. The other end plugs onto the pins of the data pod. |
| Data Pods |
 |
A complete set of logic analyzer data pods is included. Each pod uses a 13.5" cable (8 data input pins and 3 ground pins) to connect to the analyzer. This is a fully active buffered pod with more than 100MHz digital bandwidth. A full set of clips and wires is included with the logic analyzer. In addition, you can make your own custom wire assembly with a standard header connector. |
