3. Set Generator Channel 1 as below.
Output Frequency: 5 kHz
Output Level: 3500 mV rms
Output Waveform: Sine
DC Offset: 0 V
Output Type: Unbal
Output Impedance: 50

4. Adjust the output level of Generator Channel 1 so that the
measurement level of Analyzer Channel 1 will be 3500 mV rms.
This value will be the correction value of 3500 mV rms
([Syscal_Unbal_3500] (mV rms)).
5. Change the setting level of Generator Channel 1 so that the
Analyzer Channel 1 will be in the measurement level of the
measurement point No. 2 or of bigger number in Table 4.3.1-1,
and obtain the correction value.
6. Set Generator Channel 1 as below.
Output Frequency: 5 kHz
Output Level: 3500 mV rms
Output Waveform: Sine
DC Offset: 0 V
Output Type: Bal
Output Impedance: 100

7. Adjust the output level of Generator Channel 1 so that the
measurement level of Analyzer Channel 1 will be 3500 mV rms.
This value will be the correction value of 3500 mV rms
([Syscal_Bal_3500] (mV rms)).
8. Change the setting level of Generator Channel 1 so that the
Analyzer Channel 1 will be in the measurement level of the
measurement point No. 2 or of bigger number in Table 4.3.1-1,
and obtain the correction value.
