By putting the whole of  measuring instruments in the anechoic boxes, the mutual interference through connectors is prevented at the time of USB or LAN communication. <\/p>\n<p>Moreover, since our handheld spectrum analyzer is capable of battery operation, extra cables are unnecessary.  The initial cost can also be minimized.<\/p>\n\n\n\n<h2>Solution<\/h2>\n<p>\u2780 A measuring antenna suitable for target frequency is installed in a small anechoic box.  And then MSA438 is adjusted to a frequency band to be measured.  The following photo shows a screen  measured by spectrum analyzer being adjusted to 2.4-2.5GHz band. <\/p>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/eng\/image\/application\/nfc-00.jpg\"
