- All three cards have a transmitting frequency range of 2.4 GHz to 2.4835 GHz with a transmitting power measured at the antenna of 100 milliwatts. The radio functions as a "frequency hopper" and by definition will "hop" between a preset range of frequenci

The SNOOP MODE display shows the RF spectrum that the wireless monitor radio uses. If the site
survey is for a new SMI wireless monitor installation, there should not be any activity in this spectrum. If
there is, other wireless products or noise sources are in the area. The activity characteristic of a spread
spectrum, frequency-hopping radio is several peaks per screen update. Once the activity in the RF
spectrum is identified, power the WNI on. You should now see the typical display as above.
A display as shown in the following example indicates the presence of interference in the wireless radio
frequency band. This interference may be due to microwave ovens, or other wireless products. Note any
difficulties encountered on the survey forms. These difficulties should be noted even if the interference
seems to go away during the survey. Flag these problems and refer them to Spacelabs Technical
Support along with the completed survey forms. If interference is severe, contact Technical Support to
obtain a 2.4 GHz Spectrum analyzer for completion of the survey.
