2. Set the carrier frequency level (the center frequency
level of the spectrum analyzer) to the REFERENCE
LEVEL when no signals are input.
3. Input 1 kHz, _30 dBV (_27.8 dBm) signal to the MIC
INPUT connector (with Mic input cable) from the audio
analyzer (oscillator).
4. At this time, confirm that the bandwidth at the level
_23 dB lower than REFERENCE LEVEL is in
specification.
