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.
 
Frequency accuracy :
± (3 ppm of setting + 2 pHz)
(External frequency reference of 10 MHz usable.)
Frequency resolution :
0.01 µHz
Amplitude accuracy :
± (1% of amplitude setting [Vp-p] + 2 mVp-p)/open
Phase setting resolution :
0.001° (setting range: –1800.000° to +1800.000°)
Duty setting range :
0.0000% to 100.0000%; resolution: 0.0001%
Pulse wave rising/falling time:
15.0 ns to 58.8 Ms; 3-digit resolution/0.1 ns
Resolution of arbitrary waveform data amplitude:
16 bits
 
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.
