GSM-20H10提供±210V / ±1.0*** / 22W的四象限操作。在***象限和第三象限，它们作为电源运行，为负载供电。在第二和第四象限，它们作为负载使用，在内部耗散功率。而电压值、电流值和电阻值可以在电源或负载操作期间进行量测，其准确度高达0.012%并且分辨率可达1μV/10pA/10μΩ。
采样的速度上，GSM-20H10支持***高50k点/每秒的采样速度，可更精准地针对待测物的特性进行分析。透过4.3寸的大尺寸屏幕，更可以将所有的量测设定、参数与结果都完整的显示在屏幕上。支持SDM (Source Delay Measure)功能，可设定信号产生变化时，延后进行采样，避免稳定前的信号被撷取进去造成误判。内建四种程序输出模式(Linear, Log, SRC-MEM, Custom)，***多可支持2500个点的程序变化输出。
在设备保护上，GSM-20H10提供了OVP/OTP保护模式；在OVP的设计上，使用者可自定义OVP的范围，而OTP的保护则可有效防止在测试过程中因温度偏移造成的错误。在接口部分，本产品支持标准的SCPI指令，提供RS-232 , USBTMC , LAN, GPIB (选配)等接口，满足用户不同的接口需求。
