Specifications	Model 4013DDS
Waveforms
Sine, square and triangle waveforms
Operating Modes
Continuous	Output continuous at selected frequency.
Symmetry	Square symmetry is continuously adjustable from 15% to 85%.
Sweep	The output waveform can be linear or logarithmic internally swept, up or down, over the full unit range. The sweep start and stop frequencies can be independently adjusted and the sweep rate can be set from 100ms to 30s.
Frequency Characteristics
Range	0.1 Hz to 12 MHz for Sine and Square waveforms. To 1 MHz for Triangle waveforms.
Control	The frequency is selected with front panel up or down keys and modified with a rotary digital control.
Display	Up to 4 digits with large, bright LCD, ranging units (MHz, kHz, Hz and mHz) and decimal point. Waveform accuracy is 0.01% (100 ppm).
Output Characteristics
Amplitude Range	Up to 10 Vp-p into 50Ω (20 Vp-p into open circuit)
Amplitude Control	> 20 dB continuously variable.
Amplitude Attenuator	20 dB.
Amplitude Flatness	±1 dB to 12 MHz.
Offset Range	Variable up to ±10V (±5V into 50Ω). Absolute peak amplitude plus offset limited to ±10V (±5V into 50Ω).
Output Impedance	50Ω
Output Protection	The generator main output is non-destructively protected against short circuit to ground or to any voltage practically available in electronic laboratories.
Waveform Characteristics
Harmonic Distortion	< -55 dBc, 0 - 20 kHz (< 0.25%) < -50 dBc, 20 kHz - 100 kHz < -45 dBc, 100 kHz - 1 MHz < -35 dBc, 1 MHz - 12 MHz
Spurious	< -55 dBc, 0 - 1 MHz
Triangle Linearity	> 99% to 100 kHz.
Square Transition Times	< 20 ns (10% to 90%) at full output amplitude terminated into 50Ω.
Inputs and Outputs
Sync Out	TTL level square wave at generator frequency, in phase with main output and 50Ω impedance. Can drive > 20 TTL loads.
