frequency of channel B”. The setting method of frequency, period, amplitude, Vpp,
Vrms, waveform, duty cycle of channel B is the same as those of channel A.
Setting of harmonic waveform of channel B:Set the frequency of channel B is the
once harmonic waveform of channel A.
【Harmo】【1】【n】
Phase shift of channel B: Set the phase difference between the two channels is 90°
【Phase】【9】【0】【°】
1.5.3 Frequency sweeping of channel A: Press the key of 【Sweep】. Sweeping
signal is output from channel A. Use default parameters.
Setting of sweeping mode:Set the sweeping mode to be to-and-fro.
Press the key of【Menu】to light the indicator light of “Sweep” and then press
【2】【n】
Setting of other parameters is described in 3.4.
1.5.4 Frequency modulation of channel A
Pressing the key of【 FM】,the signal of frequency modulation( FM) is
output from channel A. The default parameters are used.
Setting of frequency deviation modulation : Set the frequency deviation
modulation to be 5%
Press the key of 【Menu】 to light the indicator light of “Devia”. Press the keys
of 【5】【%】.
The setting of other frequency deviation modulation parameters will be described
in 3.5.
1.5.5 Initialization or reset state
The initial working state after start-up or resetting by pressing the key of
【reset】 is as follows:
Waveform of channel A and channel B:sine
