CIRCUIT DESIGN FOR GROUND ISOLATION AMONG OUTPUT/INPUT TERMINAL, INSTRUMENT CHASSIS, AND DUAL CHANNELS
Channel 1, channel 2, reference 10 MHz input, synchronization and modulation input/output
connector grounding are isolated from instrument chassis. The output channels of dual channel
models are independently isolated. 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 units
output can be achieved without factoring in grounding reference issue. Applications include
ignition controller or transmission devices of automotive electronics. The built-in DC bias voltage
of the AFG-3000 Series can be applied on various waveforms. The DC bias voltage is ±5V
under 50 load. For automotive electronic applications require higher DC bias voltage such asW
ignition controller or transmission devices, the external power supplies can be used to bring up
the DC bias voltage to ±42Vpk (DC+ AC peak value).
GW Instek AFG-3000 Series arbitrary function generators include 20MHz/30MHz single isolated channel and 20MHz/30MHz dual
isolated channel models, designed to meet industry, scientific research, and education applications. Not only output channel is earth
ground isolation, dual channel models are also independently earth ground isolation, which is suitable for floating circuits (up to ±42V).
Without taking grounding reference into consideration, each channel of dual channel models can be operated independently and multi
ARB units can output simultaneously. Applications are, for instance, the ignition control or transmission device of automotive electronics.
The series features sample rate of 250MSa/s, 16-bit resolution, and 8M point memory depth arbitrary waveform characteristics. Users
can rebuild maximum 8M memory depth waveforms through using a GW Instek digital storage oscilloscope with the built-in DSOLink
function of the AFG-3000 Series.
MULTI CHANNEL SYNCHRONIZED PHASE OPERATION
Users can implement multi channel synchronized phase operation up
to 6 units and 12 channels (AFG-3032/3022). There are two methods
to execute synchronized phase applications. Under different frequency,
master unit can synchronize each channel and modulate individual phase.
Method one uses reference frequency output (REF OUT) and reference
frequency input (REF IN), 50 ohm BNC cable (RG-58A/U) and T type BNC
connector to connect up to 6 units to conduct synchronized phase operation.
Method two uses reference frequency output (REF OUT) and reference
frequency input (REF IN) ), 50 ohm BNC cable (RG-58A/U) to connect
up to 4 units to conduct synchronized phase operation.
At 10 MHz reference frequency input (REF IN) connector,
users can input 10 MHz atomic clock frequency standard via
external signal source to enhance precision for frequency output.
The main features of the AFG-3000 Series include output amplitude from 1mVpp to 10Vpp (connected with a 50 ohm load);
frequency range from 1uHz to 20MHz or 30MHz; 1uHz frequency resolution; and built-in sine, square, pulse, triangle, ramp, DC voltage,
harmonic and noise. The waveform width, rise edge time and fall edge time of pulse waveform can be adjusted flexibly. Pulse waveform,
with duty cycle from 0.017% to 99.983%, can be applied as trigger signals. Users can conduct arbitrary editing via 65 built-in function
waveforms. The series supports AM/FM/PM/FSK/PWM modulation, frequency sweep, amplitude sweep and burst to satisfy industrial
application requirements. Dual channel models provide SUM modulation, coupling, tracking, and phase to meet the test requirements of
differential signal, phase control and amplifier distortion. Built-in 8th harmonic signal generator simulates harmonic signal of switching
power supplies and it also tests EMI power filter characteristics. The AFG-3000 Series provides free arbitrary waveform editing
software (AWES) for users to quickly edit waveforms from the built-in diagrams so as to execute measurements.
The series supports synchronized phase for multi channel operation and the maximum phase synchronization operation is up to 6 units
and 12 channels. 10 MHz atomic clock frequency standard can be input via external signal source to elevate precision for frequency
output. The series supports frequency sweep and amplitude sweep that can also integrate functions, including linear/logarithm, one-way
(saw tooth)/two-way (triangle) waveforms, continuous/single trigger/gated trigger to meet various application requirements by applying
different sweep methods. Frequency sweep tests the frequency response of electronic components such as filter and low frequency
amplifier. Amplitude sweep simulates vibration tests (requires a vibration tester), and it also conducts aging tests of various materials
and linearity tests of low frequency amplifier.
