在TEXTOR托卡马克上，128通道电子回旋发射成像仪已被常规用于研究磁流体力学物理，如m=1和m=2模。按照目前的配置，16个混频器阵列元件中的每一个都以8个同时的频率测量等离子体发射，以形成16 cm（垂直）x 6 cm（水平）面积上的电子温度分布和波动的16×8图像。重新设计的混频器阵列，加上今年晚些时候安装的新宽带电子设备，将使等离子体覆盖范围增加到17 cm（v）× 9 cm（h）。新的配置提供了更高的温度分辨率，以及高度模块化配置中的新增益和视频带宽控制，以便于维护和促进未来在频率覆盖范围和通道数量方面的升级。
A 128 channel electron cyclotron emission imaging instrument has been routinely used to study magnetohydrodynamics physics such as m=1 and m=2 modes on the TEXTOR tokamak. As currently configured, each of the 16 mixer array elements measures plasma emission at 8 simultaneous frequencies to form a 16×8 image of electron temperature profiles and fluctuations over an area of 16cm (vertical) by 6cm (horizontal). A redesigned mixer array, coupled with new wideband electronics to be installed later this year, will increase the plasma coverage to 17cm(v)×9cm(h). The new arrangement offers increased temperature resolution together with new gain and video bandwidth controls in a highly modular configuration for ease of maintenance and facilitation of future upgrades both in frequency coverage as well as number of channels.
