GW Instek rolls out the MFG-2000 series multi-channel function generator, which has up to 5 simultaneous output channels, including CH1 and
CH2 equivalent performance dual channel arbitrary function generator with the maximum 60MHz for both channels; RF signal generator, a
standard AFG, which produces the maximum 320MHz sine wave and various modulation RF signals; pulse generator, whose frequency reaches
25MHz; power amplifier, which is ideal for audio range. The above-mentioned five different functionality channels are separately or totally
allocated on 10 models, which extend from the basic single-channel AFG with pulse generator models to five-channel models so as to satisfy
various educational and industrial applications.
The AFG channel of the MFG-2000 series outputs sine, square, and triangle, etc. The series features true point by point output arbitrary waveform
characteristics of 200 MHz sample rate, 100MHz waveform repetition rate, 14-bit resolution, and 16k points memory depth. Some models provide
various modulation methods such as AM/FM/PM/FSK/PWM, Sweep, Burst, Trigger, 150MHz Frequency Counter. Synchronized dual channel
models provide correlated functions, including synchronization, delay, sum, and coupling. RF signal generator, a complete AFG signal source
(including ARB), features various modulations, Sweep, and digital modulations such as ASK and PSK and its sine wave frequency is up to
320MHz. A full-function pulse generator with 25 MHz is equipped to all models and its pulse width, rise edge time, fall edge time are adjustable
that can be applied as trigger signals. Independent input/output power amplifier with 20W, 10dB, DC-100KHz bandwidth, and distortion less
than 0.1% can be applied to the audio application.
The overall design of the MFG-2000 series is earth ground isolation among output/input terminals and instrument chassis that can only be found
in high-level signal sources. The output channels can sustain maximum isolation voltage up to ±42Vpk (DC+ AC peak value) to earth ground that
is ideal for floating circuit tests. Multi-unit outputs can be executed without factoring in grounding reference issue. There is no additional isolation
requirement for experiments such as “full-wave rectification” and “voltage doubler” which are easy and safe. An external power supply can bring
up the DC bias voltage to ±42Vpk to meet the requirements of higher DC bias voltage such as automotive and educational applications.
The AFG of the MFG-2000 series collocating with AWES (Arbitrary
Waveform Editing Software) allows users to easily and quickly edit
arbitrary waveforms. DWR (Direct Waveform Reconstruction)
allows users to collocate with GDS series digital oscilloscopes to
retrieve waveforms and upload them to arbitrary generator to
achieve direct waveform reconstruction. 66 built-in waveforms
allow users to edit arbitrary waveforms and to output the whole
segment or divided segments.
With the multi-functionality channels, the MFG-2000 series provides
different industrial sectors with special dual channel waveforms, IQ
modulation signals, low-frequency vibration simulation, automotive
sensors, AM/FM broadcast signals, PWM motor or fan control
signals, pulse synchronized signals, pulse noise, audio circuit or
devices such as speaker tests. The series is ideal for various fields,
including scientific research, education, research and development,
production and quality control.

CIRCUIT DESIGN FOR GROUND ISOLATION AMONG OUTPUT/INPUT TERMINALS AND INSTRUMENT CHASSIS
Connection diagram for MFG connecting with a power supply
to increase D.C. bias voltage to ±42Vpk (DC+ AC peak value).
Output channels, synchronization and modulation input/output
connector grounding are isolated from instrument chassis.
These connectors can sustain maximum isolation voltage up to
±42Vpk (DC+ AC peak value) to earth ground that is ideal for
floating circuit tests. Multi-unit outputs can be executed without
factoring in grounding reference issue.
The built-in DC bias voltage of the MFG-2000 series can be
applied on various waveforms. The DC bias voltage is ±5V under
50 ohm load. An external power supply can be used to bring up
the DC bias voltage to ±42Vpk (DC+ AC peak value) for higher
DC bias applications.
