an external frequency with high resolution of 6 digits LED for 8102/8103(7digits
LED for 8105/8110). The most benefit and satisfaction can be gained from the
instrument by fully understanding its capabilities and versatility and becoming
familiar with operation procedure. One of the best ways to initially gain this
familiarization is to connect the generator to an oscilloscope. Observe the
waveforms and notice the effects of the various controls on the waveforms. Use
this manual as a reference until becoming accustomed to operating procedures.
3-3. Use As Function Generator.
1) Procedure
A. Connect AC power cord into receptacle on rear panel and plug into AC inlet.
B. To turn on equipment, push power on-off switch on.
C. To make sure that the output is symmetrical and unaffected by the sweep
generator, set the following controls as below.
CONTROLS POSITION
Sweep width OFF(push)
Symmetry OFF(push)
DC offset OFF(push)
Attenuator RELEASE(button out)
Counter INTERNAL(button out)
D. To select the desired frequency, set the Range Switch and FREQ. dial as
follows; The output frequency equals the FREQ. dial setting multiplied by the
Range Switch setting.
For example, a FREQ. dial setting of 0.6 and a Range switch setting of 10K
produces a 6 KHz output(.6x10 = 6K). A FREQ. dial setting of 2.0 and a
Range switch setting of 1M produces 2 MHz output(2.0x1M = 2M).
E. And also it can display the desired frequency by 6 digit LED display
FG-8102/FG-8103 – 7digit LED display for FG-8105/FG-8110.
F. Select sine, square, or triangle wave output by pressing the corresponding
FUNCTION button. FIG 3. illustrates the output waveforms and their phase
relationships.
G. Connect a cable from the 50
Ω
BNC to the point where it is desired to inject
the signal.
