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:

Œ Output function : sine.

Œ Stop frequency : 10kHz.

Œ Sweep waveform : ramp.

Œ Speed 1 second.

Œ 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:

Œ Output function : sine.

Œ Stop frequency : 10kHz.

Œ Sweep waveform : ramp.

Œ Speed 0.1 second.

Œ 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.
