Fluke OC4USB Serial Interface Adapter/Cable (USB)

Here's a small but essential addition to your toolbox. It's a highly-specialized USB data cable designed to work with Fluke's industry-standard scopemeters and power quality analyzers.

To understand why the Fluke OC4USB Serial Interface Adapter/Cable is so useful, you need to understand optical isolation.

Many measuring devices boast optically-isolated ports. These ensure that the ground loops which can arise when connecting up devices attached to two different ground planes do not cause interference and disturb the functioning of delicate data or test equipment. They can protect against dirty or noisy signals, and in some cases prevent damage to circuitry.

Measuring devices like Fluke's scopemeters and power quality analyzers are often installed with optically-isolated serial ports to support safe data exchange with other devices. It is impossible to read from these specialized ports unless you have the appropriate cable. Fluke's OC4USB links a robust proprietary-design serial connector to an industry-standard USB, enabling you to connect your scopemeter or power analyzer to most modern PCs. The device is compatible with Windows Vista, XP, 2000, ME and 98SE, and appropriate USB-serial converters are automatically downloaded from the Internet when you first connect the cable to your PC.

The cable is shielded and robust, and the 1.5m run gives you plenty of flexibility in setting up your PC-scopemeter linkage. Maximum Baud rate is 57.6k, and the cable meets the requirements of MIL-PRF-28800F Type III, Class 3.
