Page 18: Usage Description
FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 5. USAGE DESCRIPTION These function generators can provide versatile waveforms of high efficiency and convenient operation. Familiarize yourselves with these functions thoroughly through Operation Manual and practice with all accurate operation procedures can lead you to easily master the performance of these Function Generators. - Page 19 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 5-2.Triangle, square and sine wave (1) First select Function , and select Range , rotate FREQ , to set the required frequency.(read out from display window). (2) At this moment, connect Output , to oscilloscope for observing output signal, or connect to other experiment circuit.
- Page 20 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 5-3.Pulse wave generation (1) First press the key ( ) of Function ; then select Range and rotate FREQ , to set required frequency range. (2) Connect output-terminal to oscilloscope for observing output signal. (3) Pull out and rotate Duty to adjust the width of pulse waveform.
- Page 21 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 5-6.Variation of external voltage-controlled frequency This mode of operation allows the user to adjust the frequency of the function generator with an external DC control Voltage. It also provides an easy way for your adjustment. (1) Select Function first, then select Range , rotate FREQ set required frequency range.
- Page 22 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 5-8.AM/FM operation (1) Select function first; then select Range , rotate FREQ to set required frequency range. (2) Connect output terminal to oscilloscope for observing output signal. (3) Press MOD and pull out (press) MOD to obtain FM/AM modulation mode.

Page 24: Application Note
FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 6. APPLICATION NOTE This section describes the application of the Function Generators in details as well as a brief description relating to the block diagram. Only for the essential application method. (A) Trouble-shooting using signal-tracing method. This method is similar to signal replacing way. - Page 25 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL (D) Using the Square wave test the characteristics of amplifier circuit. It can’t actually explain the transient response of amplifier by using Sine wave for the frequency response curve observation, but using the high order poly-wave, Square wave, instead to display its waveform from the oscilloscope can show up many characteristics of amplifier.
- Page 26 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL (a) Connect the lines as Figure 7. (b) According to the operation guide in this manual, set Square wave or Pulse wave output. (c) Use the label TTL, CMOS output terminal testing TTL logic circuit. (d) To test CMOS circuit by pulling up the switch of TTL/CMOS, and adjust CMOS level by rotating the switch to set the proper level (e) Use dual-trace scope to show the input-output timing relation judged by the two waves shown in Figure 4.
- Page 27 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL (1) Series connect a R1 to the network under test as in Figure 9. (2) Get voltage read out in E1, E2, adjust R1 until E2 is equal to one half of E1. (3) Under this frequency, the impedance network is the same as the (G)Act as automatic test of speaker Because there provide the auto feature in this equipment, the output can drive to amplifier for testing the frequency response of speaker.

- Page 36 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 2).Pull apart the handle from the Function Generator. Please turn the handle left and right side slightly, that will make easier to pull off the handle. 3).There are two washers inside of two holes (the joints of handle and case) respectively.
- Page 37 FUNCTION GENERATOR-SERIES INSTRUCTION MANUAL 4).Please use a screwdriver to open the screw located at upper side of rear panel. Therefore, the upper cover can pull toward the backside. In the meantime, the upper cover is moved. Note: If you want to install the upper cover, please reverse above steps. 7-3.
