GENERAL
DESCRIPTION
The GF-8056 is a deluxe function generator
combined with a 5-digit, high-resolution 60MHz
counter.
The GF-8056 is a rugged, easy-to-
operate, excellent heat dissipating and high
stability instrument.
The GF-8056 is a 4-in-1 instrument. It can be
used as the following described four kinds of
electronic instruments respectively:
1. As a Function Generator:
Eight waveforms selected by a rotary switch
instead of push-button to prevent accidental
touching or bad connections. Maximum output
20Vp-p (no load) and minimum output 0.1Vp-p
(no load).
2. As a Pulse Generator:
The GF-8056 provides positive pulse and reverse
negative pulse output with the Pull Reverse
Switch, maximum output 20Vp-p (no load).
Frequency display by the LED, pulse width from
0.4sec to 100ns. Can meet most audio, video
and
other
basic
requirements.

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.
4. As a Counter:
The GF-8056 is a 5-digit, micro-controlled
counter. The GF-8056 features auto-range, auto-
gate time and high-resolution - 0.001Hz, input
impedance - 1M , bandwidth - 0.2Hz~60MHz,
voltage resistance - 150Vp-p. Other features the
GF-8056 provides: adjustable trigger +2.5V with
LED indication. Display unit auto-indicate, HF /
LF selector, 100kHz filter.
5. As a DC Voltage:
The GF-8056 provides a DC output function. The
output voltage can be adjusted from +10V to –10.
It can be used as a low-power DC source.
