Shorter product life and increased technology drive the need for configurable test systems that maximize manufacturers’ investments. The introduction of the Series 2600A System SourceMeter instruments updates the existing Series 2600 instruments to address the parallel test requirements and timecritical applications of today’s test engineers.
Just what improvements were made? Table 1 provides an overview of the significant differences between the Series 2600A and the Series 2600.
表1
2600系列和2600A[3]系统数字源表特性/能力比较 | | | | | | 内置ICL，可以配置线性、日志和清单扫描。直接与触发模型连接，实现精密定时控制。 | | | | | 最小脉宽= 200μs。脉冲同步只限于两个通道。SMUA脉宽必须比SMUB脉宽宽40μs。 | 最小脉宽 =100μs。能够从多个节点输出同步脉冲，与脉宽无关。 | | | | | 仅使用多个TSP-Link网络。只有通过数字I/O端口之间的外部线缆，才有可能实现同步。 | 在单个TSP-Link网络中，可以实现异步和同步并行测试。同步操作不需要额外线缆。 | | | | | | | | 源噪声因型号而异。2601/02/11/12 型噪声比2635/36型噪声高。 | 2601A/02A/11A/12A型源噪声较低，满足2635/36规范。所有型号的源噪声都低于20mVp-p (典型值)。 | | | | | | |
Current users of the Series 2600 SourceMeter instruments will find migrating their applications to Series 2600A instruments easy. Nearly all the commands for the Series 2600A are backward compatible， so existing programs should run with little or no modification. Better still， with some code modification to support the new trigger model， the Series 2600A offers users the potential to achieve throughput improvements， as well as synchronization of source and measure operations across multiple units.
To highlight the advantages the Series 2600A offers， thisapplication note considers new features in light of common semiconductor test applications.
