Waveform parameter changes and data entry can be made using the front panel rotary knob. The unit generates superb quality waveforms with high signal precision and stability. It provides sine & square wave outputs over the frequency range from 0.1 Hz to 20 MHz in one extended range (triangle/ramped wave outputs to 2 MHz). A full range of triggering capabilities is available, including internal-external trigger source and gated modes of operation. ■ 20MHz Frequency Range (sine & square only) ■ Sine, Square & Triangle ■ Modulation in both AM & FM ■ Lin or Log Sweep Function ■ Adjustable Duty Cycle ■ Adjustable DC Offset ■ Bright Informative LCD ± 4.5V into 50Ω, depending on the Amplitude setting 10 mV with 3 digits resolution ± 2% ± 10mV into 50Ω 50Ω The instrument output is protected against short circuit or accidental voltage practically available in electronic laboratories, applied to the main output connector WAVEFORM CHA RACTERISTICS Harmonic Distortion (for sine 0-20KHz, -50 dBc, 20KHz-100KHz, -45dBc wave at 5 Vp-p into 50 Ω) 100KHz-1MHz, -40 dBc, 1MHz-20MHz, -30 dBc Spurious DC-1MHz,
