美国Pragmatic设计公司研制成纯模拟集成电路或数字与模拟混合集成的电路测试仪。这个叫做Inspector的仪器有28个模拟测试脚、22个数字测试唧、11个继电器驱动器和4个可编程电源,可测各种A/D、D/A转换器、专用的模拟-数字芯片等。系统核心是4MHz的Z-80 CPU、32K RAM、CP/M、两个8英时软盘和一个CRT。程序是用TBASIC-7编写的,它是BASIC的扩充,适用于测试模拟电路。仪器的测试可更换。在同样的Z80机控制下,用不同程序和测试头,可测TTL电路、24或48引线的MOS电路。
US Pragmatic design company developed pure analog integrated circuits or digital and analog hybrid integrated circuit tester. Called the Inspector, the instrument has 28 analog test feet, 22 digital test jacks, 11 relay drivers and 4 programmable power supplies for various A / D, D / A converters, dedicated analog-digital chips, etc. . The core of the system is a 4MHz Z-80 CPU, 32K RAM, CP / M, two 8-inch floppy disks and a CRT. The program is written in TBASIC-7 and is an extension of BASIC for testing analog circuits. Instrument testing can be replaced. In the same Z80 machine control, with different programs and test head, TTL circuit can be measured, 24 or 48 lead MOS circuit.
