GP-241xx devices are set of a high-speed programmable bidirectional interfaces that allows the stimulation and the analysis of digital electronic systems. Connected to a PC through a USB 2.0 interface and using a fully programmable hardware accelerator, GP-241xx devices enable a flexible and powerful access to electronic system boards and electronic devices under test.

The GP-241xx can be turned into an arbitrary digital pattern generator, logic analyser or serial protocol master / anlyser, that fits in 16 address/data lines and 6 control lines, up to 100 MHz (200 MByte/s burst performance). According to the device model, a total internal memory of 8 MByte, 16 MByte or 32 MByte is available.

Data / Pattern Width
Maximum Frequency
Embedded Memory
GP-24100 16 bits 100 MHz 8 MByte
GP-24116 16 bits 100 MHz 16 MByte
GP-24132 16 bits 100 MHz 32 MByte

GP-241xx devices are able to sustain a theorical continuous throughput of 48 MByte/s. The actual throughput for continuous transfer depends on the host PC performances and can be expected between 11 MByte/s and 30 MByte/s. For most usages – and only for 3.3V I/O standards –GP-241xx device is powered directly through the host PC USB connection, enabling a very quick device setup. Additionally, an external power supply can be connected to the GP-241xx devices when higher current must be sinked through the system or when another I/O voltage is required.
