6.10 Setup of LIN or LOG Sweep
SFG-830 can adopt frequency to sweep its function output for triangle and ramp
waves. The type of sweep can be set as linear or log sweep.
n Select a main waveform by [ ] or [ ] button in FUNCTION column.
o Set triangle or ramp sweep mode by [ ] or [ ] button in SWEEP /
MODULATION column.
p Press [ LIN S ] or [ LOG S ] button.
q Press [ RATE ] to set up sweep RATE/TIME (range 0.001Hz ~ 1kHz).
r Press [ STAR ] and [ STOP ] buttons to set up the starting and ending sweep
frequency. This can also be done by pressing [ SWP CF ] and [ SPAN ].
sPress [ MOD ON/OFF ] to initiate sweeping.
Note: Please refer to the example in next page for the setup of LIN Sweep.
Example of the Setup of LIN Sweep
To set the following conditions:
Output function : sine.
Stop frequency : 10kHz.
Sweep waveform : ramp.
Speed 1 second.
Start frequency : 1kHz.
Procedure:
n Use[ ] or [ ] button in FUNCTION column to select SINE waveform.
o Then use [ ] or [ ] button in SWEEP/MODULATION column to select
RAMP waveform.
p Press [ LIN S ] button.
q Press [ RATE ], [ 1 ], [ Hz ].
r Press [ STAR ], [ 1 ], [ kHz ] first; then press [ STOP ], [ 1 ], [ 0 ], [ kHz ].
s Press [ MOD ON/OFF ] to start sweeping.
Example of the Setup of LOG Sweep
To set the following conditions:
Output function : sine.
Stop frequency : 10kHz.
Sweep waveform : ramp.
Speed 0.1 second.
Start frequency : 1kHz.
Procedure:
n Use [ ] or [ ] button in FUNCTION column to select SINE waveform.
o Then use [ ] or [ ] button in SWEEP/MODULATION column to select
RAMP waveform.
p Press [ LOG S ] button.
q Press [ RATE ], [ 1 ], [ 0 ], [ Hz ].
r Press [ STAR ], [ 1 ], [ kHz ] first; then press [ STOP ], [ 1 ], [ 0 ], [ kHz ].
s Press [ MOD ON/OFF ] to start sweeping.
