Abstract

It is an object to provide a device making it possible to simplify displays of data of the Code Domain Power and data pertinent thereto.

A physical quantity display device 1 for displaying physical quantity of multiple signals, which displays physical quantity in every predetermined channel while demodulating signals onto which channels with different spreading code length are multiplexed, which device is provided with a channel storage section 20 for storing display object channels to be displayed and spreading code length of the display object channels, a power calculation section 30 for calculating power of the display object channels, and a power display section 40 for displaying the power of the display object channels, which is capable of displaying the power about the display object channel stored in the channel storage section 20, and which is capable of displaying the display object channels with different spreading code length simultaneously because coexistence of different spreading code length of the display object channels is allowed.

Claims

1. A physical quantity display device for displaying physical quantity of multiple signals in every predetermined channel while demodulating signals onto which channels with different spreading code lengths are multiplexed, comprising:

a channel storage means for storing therein both display object channels to be displayed and said spreading code length of said display object channels;
