Wide Array of Output Waveforms |
OUTPUT WAVEFORMS:
Sine, Square, Pulse, Ramp, Arbitrary waveforms, Noise, DC
|
In addition to generating standard waveforms such as sine
and square waveforms, it is possible to generate arbitrary waveforms
of up to 512k words. Up to 128 waveforms can be stored in the
4M-word memory. All the generated waveforms have 16-bit high
resolution. High-quality waveforms are indispensable for improvement
in the repeatability (OR reproductivity) of tests.
Arbitrary waveforms can be set on the main unit, and the provided
arbitrary waveform creation software “Arbitrary Wave
Editor” makes waveform editing smooth. |

Various Oscillation Modes |
 |
Sweep and Modulation Functions
|
It’s possible to perform sweeps not only of
frequencies, but also of amplitudes, phases, offsets and duties (0%
to 100%). In sweeping, it is possible to combine one-way or shuttle,
linear or logarithmic slope*, and continuous, single-shot or gated
single-shot modes.
FM, FSK, PM, PSK, AM and DC offset modulations and PWM mode are
supported. Internal and external modulations are possible.
*Logarithmic mode is supported only for frequency sweeping. |

Burst / Trigger / Gate |
In the burst oscillation mode, oscillation can be started
or stopped at any wave count.WF1947 and WF1948 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
trigger
The phase where oscillation starts/stops and the level at which
oscillation starts/stops can be set. |

As Pulse Generator |
| You can use this waveform generator as a signal source
for digital circuits or a pulse generator. The duty/time and the
rising time/falling time of pulse waves can be individually set. The
generator is suited to the operation testing of a wide variety of
digital equipment and devices, data transmission equipment and more.

2-channel Ganged Operation |
The dual-channel WF1948 offers channel modes of two
phases, constant frequency difference, constant frequency ratio and
differential outputs. Various types of sweeps are possible withthe
two channels in ganged operation mode.
Each channel has a floating output terminal. |
|
Independent output (Indep)
Two channels programmed separately. |
|
Two phase (2-Phase)
Same frequency. |
|
Constant frequency difference
(2-Tone)
Difference in frequencies is constant. |
|
Constant frequency ratio
(Ratio)
Ratio of frequencies is constant. |
|
Differential output (Diff)
Reverse phase waveform with identical frequency,amplitude, and DC
offset.
|
Two Channels Independent
|
Differential Output

|
Other Functions |
|
External 10MHz frequency
reference input, frequency
reference output, synchronous operation of multiple ge6nerators
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). |
|
External addition
input
This adds external signals to the waveform output signal. |
|
User-defined
unit
The value in any unit can be set using a specified conversion
expression.(Frequency, period, amplitude, DC offset, phase, and
duty) |
