Step Procedure
1 Press the [Preset] key.
2 Operate All Cal.
3 Set the LPF cut-off frequency to approx. 12.8 MHz.
4 Set the SG output frequency to 10 MHz and the output level to –30 dBm.
5 Set the spectrum analyzer as shown below:
Center Freq..............................................10 MHz
Span.......................................................... 10 kHz
Reference Level ................................... –30 dBm
Attenuator..................................................... 0 dB
6 Adjust the SG output level so that peak of the spectrum waveform is at the REF LEVEL (the
top horizontal line of the screen).
