Powering the Analyzer on for the First Time
Insert the battery into the analyzer or connect the 
analyzer to an external power supply via the 
AC- DC adapter, then press the power switch on 
the front panel of your N934xC to power on the 
analyzer.
Allow the analyzer to warm- up for 30 minutes 
before making a calibrated measurement. To meet 
its specifications, the analyzer must meet operating 
temperature conditions.
CAU-CAUTION
Use only the original AC-DC adapter or originally supplied 
battery for the power source.
The maximum RF input level of an average continuous 
power is 30 dBm (or +
50 VDC signal input). Avoid 
connecting a signal into the analyzer that exceeds the 
maximum level.
