4014B - 

Models 4014B and 4040B are 12 MHz and 20 MHz DDS (direct digital synthesis) function generators that generate stable and precise sine, square, and triangle waveforms. Both models provide variable output voltages from 0 to 10 Vpp into 50 O (up to 20 Vpp into open circuit), linear and logarithmic sweep, AM/FM modulation, built-in counter, and a continuously variable DC offset that allows the output to be injected directly into circuits at the correct bias level.

Features:

Sine and square waveforms up to 12 MHz (4014B) or 20 MHz (4040B)

Triangle/ramp waveforms up to 1 MHz (4014B) or 2 MHz (4040B)

Bright color display with waveform preview

Linear and logarithmic sweep

AM/FM modulation

Independent output and DC offset amplifiers allow for small amplitude output signals with large DC offsets

Low-jitter square wave generation

Adjustable duty cycle

Output ON/OFF button

Internal/external triggering

Gate and burst mode (4040B only)

Built-in counter

USB interface

SCPI-compliant command set

Short circuit and overvoltage protection on all inputs and outputs
