NOTICE BEFORE OPERATION 1. Unpack the instrument: Hints for operating the instrument: Observe the following suggestions for successful instrument operation. After receiving the instrument, immediately unpack and inspect it for any damage which might have occured during transportation or shortage of accessories. If any signs of damage and/or shortage of accessories are found, notify the dealer immediately. 1. Never place heavy objects on the instrument. 2.
GENERAL DESCRIPTION 3. As a Sweep Generator: The GF-8056 provides linear sweep or log sweep. Use the selection switch to select the sweep mode. Maximum sweep width 1:100 and sweep speed 5sec to 10ms. Also, the GF-8056 provides VCF input and synchronous output function. Easy-to-operate. The GF-8056 is a deluxe function generator combined with a 5-digit, high-resolution 60MHz counter. The GF-8056 is a rugged, easy-tooperate, excellent heat dissipating and high stability instrument.

FRONT PANEL DESCRIPTION 14 13 12 11 10 9 8 7 6 15 5 1 2 16 17 18 1. Power Switch: Pushing the switch “ON” will light the LED digits (14) to indicate power “ON”. 19 4 3 12. Hz: The lit LED indicates the display units are “Hz”. 13. kHz: The lit LED indicates the display units are “kHz”. 2. Frequency: Turn the switch to set the desired frequency generated. This knob is for micro-adjust. 14. LED Digits: 5 digits indicates the frequency generated or the EXT input.
OPERATING INSTRUCTIONS WARNING: Before applying power to your GF-8056, make sure that the input voltage setting is correct for your power source. CAUTION: All the knobs are set to “PUSH” position on operation if not special marked to be set at “PULL”. (A) Function Generator and Inspection 4 5 7 6 1 3 2 6. Turn the AMPLITUDE knob to adjust the amplitude of the signal output to CH1.
(B) Sweep Generator 7 6 5 4 6 1 8 3 2 1. Turn on the power switch and make sure the LED’s of the 5-digit display light. 6. The AMPLITUDE and FUNCTION knobs will operate as a generator. 2. Connect the main OUTPUT BNC to the CH1 input BNC of your oscilloscope. 7. The frequency shown on the 5-digit LED display is the generator’s before “PULL SWEEP ON”. This frequency will be the start frequency. After “PULL SWEEP ON”, the sweep condition, including frequency, waveform, sweep mode, etc.
(C) Pulse Wave Generator 5 4 9 8 1 6 3 1. Turn on the power switch and make sure the LED’s of the 5-digit display light. 2 6. Set the pulse width by adjusting the knob (6). 7. Pull the knob (6) to display the negative pulse position. 2. Connect the MAIN OUTPUT BNC to CH1. 3. Connect the SYNC OUTPUT BNC to CH2 and set the trigger source of the oscilloscope on CH2. 8. Turn the AMPLITUDE knob to adjust the amplitude of the signal output from the main output BNC (2).
(D) Frequency Counter 2 3 1 4 3 1. Turn on the power switch and make sure the LED’s of the 5-digit display light. 3. Connect the EXT INPUT BNC to the external signal source, the EXT LED lights. 2. DISPLAY: The coupling provides 4 steps. 4. Display unit: The display unit of the GF-8056 will be on Hz or kHz automatically controlled by CPU. (a). INT/Hz: To use the internal counter from 0.05Hz to 5kHz. (b). INT/kHz: To use the internal counter from 0.5kHz to 5MHz. (c).
