嗨 - 标记沿着迹线移动，通常设置为1001个迹线点。
因此，每个跟踪点由span /（跟踪点-1）间隔开。
例如，如果您的中心频率为50 MHz且跨度为10 MHz，则每个跟踪点间隔10E6 /（1001-1）= 10 kHz。
要打开增量标记并将标记移动到-2.5 MHz（这是-250个跟踪点），您将执行以下操作：calc：mark1：mode delta calc：mark1：x：pos -250要关闭delta标记和
然后将其重新打开并移动标记5 MHz执行以下操作：计算：标记1：模式位置计算：标记1：模式增量计算：标记1：x：位置500最终结果是您有标记+/- 2.5 MHz
并且分析仪显示它们之间的幅度差。

Hi -
The markers move along the trace, which is typically set to 1001 trace points. So, each trace point is spaced apart by the span / (trace points – 1). If for instance your center frequency is 50 MHz and your span is 10 MHz, then each trace point is spaced 10E6/(1001-1) = 10 kHz apart.
To turn on the delta marker and move the marker to -2.5 MHz (which is -250 trace points) you would do the following:
calc:mark1:mode delta
calc:mark1:x:pos -250
To turn off the delta marker and then turn it back on and move the marker 5 MHz do the following:
Calc:mark1:mode pos
Calc:mark1:mode delta
Calc:mark1:x:pos 500
The end result is that the you have the markers +/- 2.5 MHz and the analyzer is showing the delta in amplitude between them.
