电子管6J1的主要特性
01 灯丝温度
一、前言
前面对真空电子管增加了底座排针， 这样便可以在面包板上对其进行测量。 下面测量几个 6J1 真空管的一些主要特性曲线。
二、阳极电压
这是测量电路。 电子管 6J1 连接成三极管的模式， 灯丝施加6.1V 直流电压。 测量阳极电压 VDD 与 阳极电流之间的关系。 利用电流采样电阻 R1两端的电压， 计算出演技电流。 此时栅极电压设为 0V。
使用两个数字万用表， 同时测量 真空管的阳极电压以及电流采样电阻R1 的电压。 这样可以获得阳极电压与电流之间的关系。 阳极电压从 0V 一直增加到 120V。 每次改变电压， 停留2秒钟再测量电流采样电阻电压。 计算出阳极电流之后， 绘制出对应的阳极电压与电流之间的关系。 这是测量的结果。 可以看到阳极电流随着阳极电压线性上升。 这是串联另外一个 64V电压源， 测量更大范围内阳极电压与电流之间的关系。 不知道为什么， 在电压超过120V之后， 阳极电流出现了非常不稳定的变化。 具体原因不详。

三、灯丝电压
测量灯丝电压与阳极电流之间的关系。 通过直流电压源给灯丝提供不同的电压， 使用同样的电流采样电阻测量阳极电流。 工作电源使用 120V 电源。 这里给出了 灯丝电压与阳极电流之间的关系。 可以看到阳极电流随着灯丝电流的增加而飞速增加。 这是 灯丝电压变化到 9V 的过程中， 阳极电流的大小。 当阳灯丝电压超过6.3V之后， 阳极电流增加放缓。 这也说明了为什么灯丝电压被定为 6.3V的原因了。

测量电子管栅极电压与阳极之间的关系。 利用可编程电压源给真空电子管栅极提供负的偏置电压。 利用电流采样电阻R1 测量阳极电流。 这是测量的结果。 可以看到在栅极电压降低到 负6V 左右时， 电子管基本上截止。
