Above all else, function generators must be very accurate.
The WF1973 and WF1974 are high-specification instruments that deliver exceptional precision,
stability and reliability in support of a wide variety of applications.
• Output Waveforms: Sine, square, pulse, ramp, noise, DC, arbitrary and parameter-variable
Arbitrary waveforms up to 512 K words can be output.
Up to 128 waveforms can be stored in the large 4 M words memory.
Highly precise waveforms are generated using high-resolution (14-bit),
high-speed (120M samples/sec) sampling.
Waveforms can be generated easily either via the control panel
(linear interpolation of control points) or in software using the Arbitrary Waveform Editor,
which also allows external data to be imported and mathematical expressions to be applied.
Preprogrammed parameter-variable waveforms can be retrieved and edited as required.
• Oscillation Modes: Continous, burst/trigger/gate, internal/external modulation,
• sweep and sequence Sweep and modulation functions
Frequency, phase, amplitude, DC offset and duty sweeps can be performed in one-way or shuttle,
linear or logarithmic slope*, and continuous, single-shot or gated single-shot modes.
Marker and X-drive outputs are available. DC offset modulation and PWM modes are supported as well as
FM, FSK, PM, PSK, and AM—both internal and external modulation.
These function generators can address a wide range of applications, including baseband functional testing
for digital communications.
* Logarithmic mode is supported only for frequency sweeping.
In the burst oscillation mode, oscillation can be started or stopped at any wave count.
WF1973 and WF1974 support four modes;
• Auto burst: No trigger is needed
• Trigger burst: Oscillation in sync with the trigger
• Gate: Oscillation in sync with the gate signal
• Triggered gate: Gate oscillation switched on/off by gate upon trigge
The phase where oscillation starts/stops and the level at which oscillation starts/stops
can be set.
• As pulse generator
With great speed and operability, the WF1973 and WF1974 show excellent performance when used as
a pulse generator or signal source for digital circuits.
The duty/time, rising time, and falling time of pulse waves can be individually set, so these generators
are best suited to operation testing of a wide variety of digital equipment and devices, data transmission
equipment, and more.
• External 10 MHz frequency reference input, synchronous operation of multiple
A high-accuracy frequency can be output when an external 10 MHz standard signal is input into the
external 10 MHz frequency reference input (REF IN) Synchronous operation of up to six units is possible
in the form of master/slave connections*, using the frequency reference output (REF OUT) and frequency
reference input (REF IN). A multi-channel (multi-phase) oscillator can be configured.
* A BNC cable is used for connection.
• User-defined unit function
AThe frequency, period, phase, amplitude, DC offset and duty can be set and displayed in desired unit
(up to four characters), using a specified conversion expression.
