FREQUENCY SPAN
RBW (resolution band width) : 1 kHz
VBW (video band width)
ATT
2. Set the carrier frequency level (the center frequency lev-
el of the spectrum analyzer) to the REFERENCE LEV-
EL when no signals are input.
3. Input 1 kHz, _36 dBV (_33.8 dBm) signal to the AF
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.
