3-2. Operating Instructions
This instrument is capable of generating a wide variety of waveforms, as well as the ability of counting
an external frequency with high resolution of 6 digits. All of its benefits and features can be mastered
by thoroughy understanding the operating procedures outlined in this manual. 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 a Function Generator
1) Procedure
A. Connect AC power cord into the receptacle on the rear panel and plug into an 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 0.5 and a Range switch setting of 50K produces a 2.5 KHz output. A
FREQ. dial setting of 5.0 and a Range switch setting of 5M produces 5 MHz output. It also can
display the desired frequency of 6 digits.
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 BNC to the point where it is desired to inject the signal.
H. Adjust the 50 output to the desired amplitude with the AMPLITUDE control.
