Basic Functions
The Model 725 provides eight functional channels, or internal signal paths.
At any time, each channel can be assigned one of eight timing modes. Timing modes include
clocks, counters, delayed pulses after triggers, etc. You can set various properties for each timing
mode—for example, the delay length on a Delayed Pulse After Trigger. All modes are aligned to a
precise, 100 MHz internal clock or an external clock, allowing resolution down to 10 ns.
Each channel also includes logic settings which specify the conditions that will trigger the
channel. A channel can be triggered by any logical combination of signals from the eight inputs
and/or the outputs of other channels.
The timing properties and logic that you set up in timerPRO can be transferred and stored in the
memory of the Model 725. You can store up to 64 variations of these properties in settings
profiles in the Model 725. You can then switch between settings profiles to switch experiments,
compare different timing scenarios, or simulate different real world conditions.
All settings and setting profiles for a particular experiment can be stored as an experiment file on
your computer. Experiment files bear a .trg extension.
How You Will Use the Model 725
In most cases, you’ll use the Model 725 as follows:
1. Using the timerPRO software, open an existing experiment file, or create a new file.
2. In timerPRO (or LabView), program the properties and logic for each channel and for the
experiment as a whole.
3. Send the properties and logic to the Model 725’s memory.
4. Test your program by simulating triggers and examining the outputs using the Model 725’s
channel LEDs and/or an oscilloscope or other diagnostic tool.
5. Store variations of channel properties in one of the Model 725’s 64 settings profiles.
6. Plug your experimental equipment to the Model 725.
7. Run the experiment, using the Model 725 by itself or leaving it tethered to the PC. Switch
between settings profiles to explore various timing conditions.
Installing timerPRO Software
Insert the timerPRO software disk in your computer drive and execute the setup.exe file.
