Picture of calibration in progress.

Instruments Currently Supported

Additional instruments can be added. Please contact me for more help.

If you cannot find a procedures document for a particular model then a similar instrument will often work equally well. This is because as instruments evolve their underlying hardware and software often do not change very much.

IMC

IMC (external link) produce a variety of measurement hardware. They also have their own software.

Spartan

The Spartan is a medium-speed data acquisition system manufactured by IMC. A PC is used to communicate to the Spartan. Data is saved in a specialised file format but can be easily converted using options within the IMC software or batches can be done using the FAMOS sequences linked to below as part of Tcal.

Optional FAMOS sequences for converting IMC files to text. (click, right-click or similar to view or download)

AMO

AMO (external link) sell the Saturn transient recorder. They also offer software and other services.

Saturn

The Saturn is a data acquisition system available in a variety of case sizes and with a variety of maximum collection speeds.

Graphtec

Graphtec (external link) sell a number of hardware products including data acquisition systems. The timebase is relatively slow but obviously adequate for many applications. Their data acquisition systems can usually be run from the machine or via a PC. Running via a PC can make calibration easier as their is more control over the data filenames.

GL220/GL240/GL820/GL840/GL900

These are compact data recorders with relatively slow collection speeds that are often used for environmental monitoring or other slower, longer-duration applications.

HBM

HBM (external link) offer a wide range of instruments including many data acquisition systems. They sell some models that are designed for rugged use.

Gen7tA

Able to take a number of cards this is a flexible system capable of high collection speeds.

Gen3i

An evolution of the Gen2i. The procedures document for the Gen2i will work fairly well for this instrument.

Gen2i

An evolution of the Vision.

Vision

The procedures document for the Gen2i will work fairly well for this instrument.

Hi-Techniques

Hi-Techniques (external link) produce high speed data acquisition systems. They build on the work Nicolet and Bakker Electronics (see below). I have heard reports of problems with these instruments when initially shipped. I have also heard reports of warranty returns solving these problems.

Synergy

High speed data acquisition systems that come with an on-board PC. They can be run with a screen, keyboard and mouse attached or by using a remote desktop application.

Pico Technology

Pico Technology (external link) offer a wide range of oscilloscopes and data recorders. In many cases their instruments can act in both modes.

4224/4424

These are entry-level instruments sold as PC oscilloscopes. They also offer data acquisition capabilities.

National Instruments

National Instruments (external link) offer a wide range of data recorders, other instruments and software.

TEAC

TEAC (external link) do not have a wide variety of products in this field but do sell the LX-100 and used to sell the GX-1.

GX-1

The GX-1 needs to be run from a laptop. The software suite for the instrument comes with a conversion application that will convert the data format into text files for analysis using the Tcal spreadsheets. Booster boxes with additional channels can be added.

Nicolet

Nicolet no longer exists as an independent company so do not have a website any more. It was created from Bakker Electronics. The rights to their instruments were then transferred to HBM and then to Hi-Techniques (if I am getting this wrong please tell me but this is approximately true).

Multipro

No longer sold. This is a legacy instrument that some are still using. I have found the analogue to digital conversions on old instruments to still out-perform modern machines as they were so well made.

Bakker Electronics

Bakker Electronics no longer exists as an independent company so do not have a website any more. The rights to their instruments were then transferred to Nicolet (if I am getting this wrong please tell me but this is approximately true).

BE256

No longer sold. A high speed data acquisition system. I have seen them fitted out with up to 48 channels. I have found the analogue to digital conversions on old instruments to still out-perform modern machines as they were so well made.

BE2570

No longer sold. A high speed data acquisition system. I have typically seen these with 8 channels. They can be operated from menus on the instrument but I have always seen them being used via a PC. The more complicated operation options might explain why I have seen them fail more than the similar BE256 systems. I have found the analogue to digital conversions on old instruments to still out-perform modern machines as they were so well made.

BE490

No longer sold. A data acquisition system in the form of a card that is added to a PC. I have most often seen these fail due to the computer not working any more while the card itself still works fine. I have seen two voltage range options. Where lower ranges are available these are often noisy possibly due to interference from the computer they are fitted into.
