Custom Engineering
Design was established in 1994 specializing in development of PC based oscilloscopes
and custom data
acquisition solutions.
Our 4 and 8 channel Oscilloscope modules are powerful, have flexible trigger options, deep acquisition memory and are easy to use. Today, we have a large customer base around the world in a variety of industries, large and small companies as well as universities and governmental institutions using our PC based oscilloscope modules in a variety of applications. |

The Oscilloscope controls have been organized in functional groups.
The Vertical Settings panel shows a summary of the configuration of all channels. It also allow the user to change settings for any channel parameter on this panel.
The Vertical Settings control the following;
| Vertical Gain : | Controls the amplification/attenuation (ie 25 mv/div, 100 mv/div) |
| Vertical Offset : | Controls the positioning of the trace (in Y direction) |
| Coupling | Select AC, DC, OFF or GND |
| Trace - Color | Select the Trace color |
| Trace - Label | Enter a 3 character label for each channel |
| Trace - Width | Set the trace width for easier identification or visual reference |
| Probe Attenuation | Select probe attenuation (1x, 10x, 100x) |
| Math | Setup additional Math channel (ie Ch1 + Ch2 or Ch3 - Ch4) |
The Oscilloscope uses the trigger functions to control when to start data acquisition.
The Simple Trigger Settings control the following;
| Signal Source : | Select the Trigger Source Channel (ch1, ch2, ch3, ch4 or external input) |
| Active Edge : | Select the Active Edge/Level of selected Trigger Source |
| Threshold | Set the threshold for the selected Edge/Level of the Trigger Source |
The simple trigger option can be used to capture many signal conditions. However, more demanding applications require more sophisticated complex trigger options. With complex trigger, it is possible to capture narrow pulses, wide pulses, runt pulses on a single or multiple channels.
The Complex Trigger Settings control the following;
| Signal Source : | Select the Trigger Source (ch1, ch2, ch3, ch4 or ext input) or a combination of input sources. |
| Logic : | Select AND or OR combinatorial logic if you have multiple trigger sources. |
| Function | Trigger on Narrow Pulse, Wide Pulse, Pulse count, Runt-Pulse or voltage level on single or combination of multiple trigger inputs. |
The Horizontal Settings control the following;
| TimeBase : | Select the horizontal acquisition rate |
| Pre-Trig Buffer : | Specify how much data should be acquired before the trigger |
| Post-Trig Buffer : | Specify how much data should be acquired after the trigger |
| Horizontal Position | View data acquired before, during or after trigger |
Two sets of Calipers are provided and can be used to perform measurements and provide visual reference.
The Caliper Settings control the following;
| Source : | Select Source (Ch1 - Ch8) |
| Auto - Tracking : | Let vertical (voltage) caliper automatically track horizontal (time) caliper movements |
The Statistics panel shows statistical parameters for each acquisition cycle.
The Statistics Settings control the following;
| Source : | Select Source (Ch1 - Ch8) |
Save and Recall Waveforms from Disk
Waveforms can be saved to disk and can be recalled from disk at any time.
Save and Recall System Configuration Files from Disk
System configuration can be saved to disk and can be recalled from disk at any time. An example usage of this is when the Scope4pc is used in Automotive testing. Create System Configuration files for your common tests, using descriptive naming of the files. This makes for easy and quick system setup.
Disk Logging is used when you want to automatically save the waveforms acquired to disk every acquisition cycle. The data files saved to the hard-disk are date and time-stamped and can be recalled and viewed on the screen later. The Disk Logging feature is especially useful when debugging spurious or infrequent signal instances. You may leave the Scope4pc on for days and see how many files were logged to disk (how many times did the problem show).
The Disk Logging Settings control the following;
| Max Files | Maximum number of files to be saved (1 - 199) |
| Delimited format : | Save data in delimited format (so that it can be imported into Excel) |
Large Oscilloscope Screen Option
The control panels described above can be hidden, giving room for a extra large oscilloscope screen area.
The Pass/Fail testing screen allows the user to define 8 separate tests. Each test is individually configured with the following settings;
| Test Type | Pass or Fail |
| Test Source | Ch1 - 4 (or Ch 1 -8 for 8 channel system) |
| Criteria | Greater Than, Less Than |
| Threshold | Select voltage level |
| Save Option | None, Save Fail data, Save Pass data, Save all Data |
