Key Features (4001A & 4003A):
Waveform Generation: Generates sine, triangle, and square waveforms from 0.5 Hz to 4 MHz, and ramp and ±pulse waveforms from 0.5 Hz to 3.5 MHz.
Variable Amplitude Output: Offers a 20 Vpp output into an open circuit or 10 Vpp into 50 ohms, with a 20 dB attenuator for precise control over output signal levels.
Linear or Logarithmic Sweep: Provides linear or logarithmic sweep functions with adjustable sweep rates and widths for effective signal analysis.
DC Offset Control: Features an adjustable ±10 V DC offset, allowing the user to inject signals directly into circuits at the correct bias level.
TTL Output: TTL-compatible output for use in digital systems.
Kensington Security Slot: Provides security in lab environments, preventing unauthorized removal.
Model 4003A Additional Features:
Built-in Frequency Counter: The 4003A model includes a 20 MHz 5-digit external frequency counter, enabling accurate frequency measurements in addition to waveform generation.
CMOS Variable Output: CMOS-level output, expanding the compatibility with digital circuits and systems.
