In this case, you have to open and close it with exactly the same frequency as the rotation of the neutron star.

在这个例子里，你必须以和中子星，旋转相同的频率，对其进行开关。

Every 90 seconds, the array switches to looking at a different star, or a different frequency range, and a new image is generated.

因为每隔90秒望远镜阵列就会切换观测另外一个星体或者一个不同的频段，一幅新的信息转换成的图像就会显示出来。

So in fact, you already know that the argument that you want to have with Mr. McKibben and the Star-Ledger, the one about hurricane frequency, the one they did not make, is in fact wrong.

FORBES: Yes, There's A Link Between Hurricane Irene And Global Warming

Dr Ardavan is confident that, if the machine can be coaxed into doing this, it will radiate in exactly the way he predicts, providing a tuneable and compact source of high-frequency microwaves in effect, a tabletop pulsar, without the neutron star.
